It grows on grassy slopes, at forest margins or along stream sides at altitudes of (2800–) 3400–4100 m above sea level. Munz (1965) stated that the type material of this species was collected from western Sikkim and Grierson &amp; Long (1984) recorded the occurrence of this species in Sikkim, but the type material was actually collected from eastern Nepal, not from Sikkim (Fig. 1). We have not as yet seen any authentic material of D. drepanocentrum from Sikkim. According to Gogoi et al. (2021), this species indeed does not occur in Sikkim.</p> <p>Phenology:—Flowering from late July to September; fruiting from September to early October.</p> <p>Additional specimens examined (barcodes are given when available):— CHINA.

(JE; Fig. 1), from the neighborhood of Wallanchún in Sankhuwasabha District, eastern Nepal (Fig. 6). According to the protologue, this variety was characterized by having sickle-shaped, incurved spur of sepals and hirsute carpels (“calcari falcato-incurvo, carpellis hirsutis”). Based on the same collection, Brühl (1896) published it as a subspecies of D. altissimum, i.e. D. altissimum subsp. drepanocentrum, with an excellent line illustration and a brief description: “a middle-sized herb; the whole stem covered with dirty-yellow more or less deflexed, partly glandular hairs; blade of leaves hairy above, subhirsute beneath; bracteoles close to the flower, linear; sepaline spur longer than the sepals, sickle-shaped; ovaries hirsute”. Munz (1968), in January, without giving any reason, raised D. altissimum subsp. drepanocentrum to specific rank, proposing the combination D. drepanocentrum (Brühl) Munz. Tamura (1968), in November, also raised D. altissimum subsp. drepanocentrum to specific rank. proposing the combination D. drepanocentrum (Brühl) Tamura. In his remarks, Tamura (1968) stressed that this species was distinguished from D. altissimum mainly by the yellowish indumentum on stem, petioles, both sides of leaves, especially on veins of abaxial surface, pedicels, sepals and carpels. He further elaborated on the morphological distinction between the two species. The hairs in D. drepanocentrum were various in length; some of them were spreading, glandulose and swollen near the base, some of them were curled or deflexed and eglandulose. On the lower part of stem, the hairs were sparse and usually curled, on the pedicels and outside of sepals, they were more dense and partly spreading, and on the carpels subvillose and not spreading. Leaf-lobes were ovate- or obovate-rhombic, regularly laciniate-dentate into the laciniae with obtuse or round tips. Bracteoles were approximate to the flower, flowers 30–38 mm long, and the spurs distinctly longer than the sepals, sickle-shaped or nearly straight. While in D. altissimum, the stem was pubescent but usually glabrous downwards, and the hairs white, curled and eglandulose, though sometimes the hairs on petioles, abaxial side of leaves and carpels were somewhat similar to those of D. drepanocentrum. Sepals were covered with white curled and eglandulose hairs and carpels glabrous or hairy. Bracteoles were usually distant from the flowers, flowers smaller than those of D. drepanocentrum, and spurs usually slightly longer than the sepals, straight or slightly curved. Tamura (1968) stated that D. drepanocentrum was distributed in western Sikkim and eastern Nepal. Hara (1979) and Rau (1993) accepted the specific status of D. drepanocentrum proposed independently by Munz (1968) and Tamura (1968). Tamura’s (1968) combination, published several months later, is an illegitimate isonym and has been rejected.</p> <p>However, without giving any reason, Mukerjee (1960) transferred Delphinium altissimum subsp. drepanocentrum to D. umbrosum Handel-Mazzetti (1931: 278) as a subspecies, i.e. D. umbrosum subsp. drepanocentrum. This treatment was accepted by Wang (1979) in his account of the genus Delphinium from China in the Flora Reipublicae Popularis Sinicae vol. 27. He noted that this subspecies was different from subsp. umbrosum by having stems shorter, 50–70 cm tall, ca. 6 mm thick (vs. taller, 60–110 cm tall, 5–12 mm thick at base), and densely spreading hirsute, with the hairs 1–3 mm long (vs. retrosely appressed puberulous, with the hairs 0.1–0.9 mm long) and also by having bracteoles 1.5–1.8 mm (vs. 0.5–0.6 mm) broad, and that it was distributed in China (southern Xizang), India (Sikkim) and Nepal. Wang &amp; Warnock in Wang et al. (1995) treated this taxon as a variety, proposing the combination D. umbrosum var. drepanocentrum (Brühl) Wang &amp; Warnock. They noted that this combination was necessitated by the editorial policy of the Flora of China Project to recognize only one infraspecific rank within a genus and that use of variety as the infrageneric rank for the Chinese Delphinium required fewer new combinations than use of subspecies. This treatment was adopted by Wang &amp; Warnock (2001) in their account of the Chinese Delphinium in the Flora of China vol. 6 and by Wang (2020) in his recently published treatise “A revision of the genus Delphinium (Ranunculaceae) of China (II)”.</p> <p>We agree with Munz (1968) and Tamura (1968) that Delphinium drepanocentrum should be recognized as an independent species of its own. This Himalayan species (Figs. 1–5) is somewhat similar to D. umbrosum (Figs. 7–9) in leaf division and bracteoles distal on the pedicel (close to the flower), but very readily distinguishable by having thicker and papery (vs. thinner and membranous) leaves mostly basal and persistent (vs. mostly cauline, with the basal ones usually having withered) at anthesis, and spreading hirsute (vs. appressed puberulent) stem, petioles, inflorescence axis and pedicels. Geographically, the two species are remarkably disjunctive, with D. drepanocentrum distributed in southern Xizang (Dinggyê, Nyalam), China and Nepal, whereas D. umbrosum endemic to northwestern Yunnan, China (Fig. 6).</p> <p>Wang (2020) described Delphinium umbrosoides on the basis of a single collection, PE Xizang Exped. 3526 (PE; Fig. 4), from Dinggyê (= Dingjie) in southern Xizang, China. In the protologue, the author stated that it was similar to D. umbrosum in having 3-partite leaves, racemose inflorescence, linear bracteoles close to the flower, and sepals shorter than the sepaline spur, but remarkably differed by having shorter plant 11–16 cm (vs. 60–110 cm) tall and 3–4 leaves all basal and persistent (vs. leaves basal and cauline, with the basal leaves having withered at anthesis). Wang (2020) also noted the holotype (Fig. 4A) was an abnormally developed plant, with the pedicel of a flower at the base of the raceme strongly elongated while the other parts strongly abbreviated, but the isotype (Fig. 4B) was a normally developed plant, with the raceme not yet mature and containing only flowering buds. According to the field record, this collection was made on 15 July, 2014, not yet the usual flowering period of the plant in question. Our specimen survey at GXMG resulted in the discovery of a Delphinium specimen, CMTTE 966 (GXMG; Fig. 5), from the exact type locality of D. umbrosoides, i.e. Chengtanggou in Dinggyê, southern Xizang. A comparison of the type specimens of D. umbrosoides with this specimen and those of D. drepanocentrum from Nepal (Fig. 1, 2) and from Nyalam in southern Xizang (Fig. 3) indicates clearly that D. umbrosoides, which is characterized by, among other characters, having spreading hirsute stem, petioles, inflorescence axis and pedicels, should be conspecific with D. drepanocentrum. We therefore place D. umbrosoides in synonymy with D. drepanocentrum herein.</p> <p>Some collections from Cona in southern Xizang, China, including Anonymous 75-1841 (PE), PE Xizang Exped. 6282 (PE), Qinghai-Xizang Supplem. Exped. 75-1642 (KUN, PE), Qinghai-Xizang Supplem. Exped. 75-1720 (KUN, PE), and Qinghai-Xizang Veg. Exped. 2471 (PE), have been identified in 1976 and 2017 respectively as Delphinium umbrosum subsp. drepanocentrum on the determination slips (two sheets of the collection PE Xizang Exped. 6282 shown in Figure 10), and Wang (2020) cited two of them, Xizang Supplem. Exped. 75-1642 (Fig. 11A, B) and Xizang Supplem. Exped. 75-1720 (Fig. 11C, D), under D. umbrosum var. drepanocentrum. These collections are indeed somewhat similar to D. drepanocentrum in the position of bracteoles on pedicels (the bracteoles close to the flower), but they differ remarkably by having somewhat deeply divided leaves, more leafy stems, densely appressed strigose stems, petioles, inflorescence axis and pedicels, and sparsely pubescent or subglabrous follicles. They should belong to a hitherto undescribed species. In addition, Wang (2020) referred another collection from Cona, PE Xizang Exped. 6212 (PE), to D. conaense Wang in Wang &amp; Li (1987: 34). This collection should also belong to the hitherto undescribed species while D. conaense is certainly conspecific with D. bhutanicum Munz (1967: 507), a species hitherto recorded to occur only in Bhutan (Grierson 1984). Geographically Cona is closely adjacent to eastern Bhutan. We will report these two species and place D. conaense in synonymy with D. bhutanicum elsewhere.</p> </div>	https://treatment.plazi.org/id/BB6E6A41FFF47974FF12FDB32452F913	Public Domain	No known copyright restrictions apply.

In the protologue, the author stated that this species was related to D. delavayi Franchet (1886: 379), but the latter species differed by having thicker leaves, lanceolate and sessile bracts, much less reflexed spur, much more obliquely truncate upper petals, densely ciliate lateral petals, and very pilose ovaries (“Affine D. Delavayi Franch. quod differt foliis crassioribus, bracteis lanceolatis sessilibus, calcare multo minus reflexo, petalis superioribus multo obliquius truncates, lateralibus crebre ciliatis, ovaries valde pilosis”). Since its description, D. umbrosum has been recognized as an independent species by Wang (1962, 1979 a, 1993, 1997, 2000, 2020), Munz (1968), and Wang &amp; Warnock (2001).</p> <p>Wang (1962) referred ten collections to Delphinium umbrosum, including C.W. Wang 69050 (PE), C.W. Wang 69052 (PE) from Deqen county in northwestern Yunnan and T.T. Yu 979 (PE), J.Q. Hu et al. 3824 (PE), J.Q. Hu et al. 3859 (PE) all from Yuexi county, J.Q. Hu et al. 1132 (PE), J.Q. Hu et al. 1554 (PE), J.Q. Hu et al. 1607 (PE), J.Q. Hu et al. 4248 (PE) all from Hongxi county (now Meigu county), and T.T. Yu 3417 (PE) from Leibo county all in southwestern Sichuan. Wang (1965) considered that only the two Yunnan collections (Fig. 8) belonged to D. umbrosum. He thus described a new variety, D. umbrosum var. hispidum, to accommodate the Sichuan collections, with J.Q. Hu et al. 1607 (PE; Fig. 12A) designated as holotype. He stated that the new variety differed from the type variety, var. umbrosum, by having stem proximally spreading hispid (vs. retrorsely puberulent) and thinner (vs. thicker) (2‒3.5 mm vs. 5‒10 mm in diameter). This treatment was accepted by Wang (1979a, 2020) and Wang &amp; Warnock (2001).</p> <p>We have examined all the type material of Delphinium umbrosum var. hispidum and determined that this variety is identical with D. omeiense, a species described on the basis of six collections also from southwestern Sichuan and since its description generally recognized by Wang (1979 a, 1984, 2000, 2016, 2020), Wang &amp; Wang (2000), Wang &amp; Warnock (2001), and Xie (2016). In fact, the four sheets of Sichuan Econ. Pl. Exped. 1607 (PE; Fig. 12A–D), which constitute the type collection of D. umbrosum var. hispidum, belong also to a paratype collection of D. omeiense (Wang 1979b; Fig. 12B), because J.Q. Hu et al. 1607 and Sichuan Econ. Pl. Exped. 1607 are actually the same collection, with Hu as the leading participant of the expedition (Fig. 12C). Our critical examination indicates that this collection is not mixed, comprising only one taxon. We will deal with D. omeiense in detail elsewhere; in addition to D. umbrosum var. hispidum, several other names should also be reduced to the synonymy of this species.</p> </div>	https://treatment.plazi.org/id/BB6E6A41FFF2797DFF12F9512448FA73	Public Domain	No known copyright restrictions apply.
