However, no herbarium was cited in the protologue. Moreover, there are three type collections with the same number and date deposited at NY, US, and UCWI (ex JM). As consequence, according to the Art. 8.1 of ICN, a lectotype is designated here among the syntypes known (Art. 9.6 of ICN), opting for NY specimen, being the most complete with all vegetative and reproductive elements.</p> <p>Taxonomical notes: ―The comparison of the illustrations and descriptions by Britton (1911: 130) and Britton &amp; Rose (1919: 161), as well as by examining herbaria specimens, supported this taxon as a distinct species from Opuntia tuna sensu auct. (see next paragraphs), differing from the other Jamaican taxon (here described as Opuntia kingstoniana), for its cladodes more sphatulate with a narrow base (vs. usually obovate), areoles oval (vs. circular), fewer spines (usually 1–2 per areoles (vs. usually 2–5), up to 2.5 cm long (vs. up to 5.0 cm long), spreading (vs. reflexed), whitish (vs. brownish-yellow), usually arranged only along the apical margins (vs. the entire surface), fruit pyriform with the lower part very narrow and elongated, 3.5–4.0 cm long (vs. short-obovoid, about 3 cm long). Also habitat and distribution areas are different between these two taxa: O. jamaicensis grows on saline soils (vs. rocky or sandy soils for O. kingstoniana), at 0–8 m a.s.l. (vs. 0–120 m), in St. Catherine and Manchester Parishes (vs. St. Andrew and St. Thomas Parishes) [see also Britton &amp; Rose 1919: 113–114, Adams 1972: 74, and Britton &amp; Harris 10887 sub Opuntia jamaicensis (NY, US), Rose 18503 sub O. tuna (US, NY)].</p> <p>Notes on flowering time: ―The plant start to flower at 11 a.m. and begin to close after 4 p. m.

Furthermore, note that the provenance of Cactus tuna reported by Linnaeus (1753: 468), i.e. “ Jamaica &amp; America calidiore ”, refers to O. dillenii for Jamaica, being this species the only one occurring in the island with this cited distribution. According to Schumann (1899: 724), O. tuna is the valid name with priority for the plant known nowadays as O. dillenii and it differs from the Jamaican species here described and collected in Kingston by Rose (O. kingstoniana).

However, his drawings in many cases are not accurate, containing errors or out-of-scale elements (see Areces 2018: 108, 112), probably because they were illustrated from memory (Mottram 2002: 86, Areces 2018: 112). Some examples are Consolea moniliformis (Linnaeus 1753: 468) Berger (1926: 94), based on Plumier’s plate 11, Harrisia divaricata based on plate 23, and Neogriseocereus fimbriatus (Lam. in Lamarck et al. 1785: 539) Guiggi (2013: 1), based on plate 25 (Britton &amp; Rose 1919: 207, Mottram 2002: 88, 2020: 2, 63). Their identification and validity have never been questioned, unlike plate 26 (Fig. 10), used by Haworth (1830: 113) to describe his Cereus serruliflorus. Franck et al. (2017: 5) suspected that C. serruliflorus was a mix with H. divaricata and interpreted their narrowed lectotype in the sense of the latter species.</p> <p>We are not in agreement with this position (Cereus serruliflorus was a mix with Harrisia divaricata) for several reasons. H. divaricata with its different characters is depicted by Plumier (1689 –1697) on plate 24. Oversized elements including the scales on the flower tube and on the fruits included in pl. 26 occur also in the previously cited cases (i.e. plates nos. 11, 23 and 25). The locality (i.e. Plaine Cul-de-Sac, Croix-des-Bouquets) of Ekman’s collection (H-5377), here chosen as an epitype of Cereus serruliflorus (see Franck et al. 2017: 2–3, Areces 2018: 116), is the same of the plant on which Plumier (1689 –1697: pl. 26) based his drawing. The morphology of the stem in Plumier’s pl. 26, with the visible crenate margins and short and weak spines, are also conspecific with those included in Ekman (H-5377), with the exception of the lower number of ribs (8 vs. 11–13; see Franck et al. 2017: 2), here considered not so decisive, in consideration of artistic interpretations or imprecise memories.</p> <p>In addition, the lectotype interpretation as Harrisia divaricata by Franck et al. (2017: 5) is in conflict with the protologue that described a large plant (to 4–5 m high, see Franck et al. 2017: 2, Areces 2018: 113) with a large fruit, subconical (Haworth 1830: 113; see also the Plumier’s plate 26), that for this reason could be rejected (Art. 9.19 of ICN). In contrast, H. divaricata is a shrubby plant (2–3 m high, see Franck 2016: 30, 115 fig. 66, 116 fig. 67) normally with globose fruit at maturity (Franck, 2016: 118, fig. 69). As support of these arguments, the morphology of the flower occurring in Plumier’s plate 26 is not the same apart the scales already discussed, as that of H. divaricata characterised by non-deflexed and triangular perianth segments and non-exserted stamens and stigma (see Franck 2016: 117, fig. 68).</p> <p>Furthermore, in the English translation of the Plumier’s description associated with the pl. 26 (Mottram 2002: 113, 2020: 64), the characters reported (“ […] the trunk is almost as thick as a man’s body […] flowers, opening wide, monopetalous, truly campanulate […], with numerous narrow acuminate fimbriate segments […]. Its pericarpel and receptacle tube with small green scale-like leaves […] having a funnelform, many-branched stigma. […] an oblong or cucumber-shaped fruit”) matches the Areces’s concept of Cereus serruliflorus (see Areces 2018: 109-113, figs. 2, 6, 9, 10).</p> <p>All things analysed, we do not consider the Plumier’s plate 26 to refer to more the one species (Art. 9.17 of ICN). Therefore, the lectotyfication of Lourteig is valid in our opinion (1991: 408), whereas that of Franck et al. (2017: 5) is unnecessary and the new species Cereus haitiensis A.R.Franck &amp; Peguero in Franck et al. (2017: 2) is also suspected to be a later homonym of C. haitiensis (K.Schum.) Schelle (1926: 120). Its replaced name Cereus ayisyen Van der Meer (2019: 14) see Mottram (2020: 64, 68) needs to be interpreted as illegitimate superfluous name.</p> <p>Taxonomic notes: ―The original inclusion of the taxon serruliflorus under the genus Cereus Miller (1754) by Haworth (1830: 113; see also Areces 2018: 113, Wisnev 2018: 223) appears inappropriate according to Guiggi (2018: 1), who highlighted that 1) the genus Cereus is not native from Caribbean region and 2) C. serruliflorus has vegetative and reproductive characters more related to other Caribbean genera, i.e Harrisia Britton (1908: 561) and Leptocereus (Berger 1905: 79) Britton &amp; Rose (1909: 433) (see Guiggi 2018: 1). C. serruliflorus is distinguishable from Harrisia and Leptocereus by the following characteristics: flower strongly reflexed with oblong perianth segments, apical margins finely serrulate, style and stamens strongly exserted from the perianth, fruit long and subconical and pendulous. This led to the description of a new genus, Serrulatocereus Guiggi (2018: 1); it would belong to the tribe Leptocereae Buxbaum (1958: 178) sensu Guiggi (2020: 1–5), but new molecular data need (see Guiggi 2020: 1).</p> <p>Notes on flowering time: ―This species has a specific flowering time during the dry season from December to March (Areces 2018: 118).</p> <p>Chorology: ―Endemic to Haiti (Areces 2018: 113).</p> <p>Illustrations examined: ― Mottram (2002: 113 Plumier plate’s 26 Fig.10), Areces (2018: 108–116, figs 2–16), Franck et al.
