6152D7AA6A6950579C0CEE4FF0B7312E.taxon	diagnosis	Diagnosis. Perrottetia taronensis is similar morphologically to P. alpestris s. s. (see Discussion) from which it differs by having much more compact and shorter inflorescences which are sparsely golden tan-tomentose rather than sparsely reddish brown-tomentose, a shorter stipe, leaf margins that are sharply serrate rather than bluntly serrate, and larger fruit when mature.	en	Bartholomew, Bruce, Armstrong, Kate E., Li, Rong, Fritsch, Peter W.

6152D7AA6A6950579C0CEE4FF0B7312E.taxon	description	Description. Shrubs or small trees 1.5 - 6.0 m tall, often sprawling, likely dioecious, deciduous. Stems reddish brown, pale brown-tomentose when young, glabrescent. Stipules reddish brown-tomentose, triangular, ca. 1.5 x 0.5 mm, often cauducous, apex long-acuminate. Petioles 0.5 - 1.0 cm. Leaves alternate, mostly glabrescent; leaf buds and young leaves dactylose (Figs 1 B, 3), reddish brown-tomentose (Fig. 3), persistent as small naked buds over winter; mature leaf blades chartaceous, mostly glabrescent, sometimes with domatia abaxially in axils of main lateral veins, when fresh abaxially pale pinkish greenish (Fig. 2 A) and adaxially dark green (Fig. 2 B), when dry abaxially pale brownish green and adaxially dark green, narrowly ovate to elliptic, 10 - 15 x 3.0 - 7.5 cm, abaxially aveolate, sometimes sparsely tomentose on veins, midvein prominent, secondary and tertiary veins prominent, adaxially rugose, glabrous, midvein slightly prominent, secondary and tertiary veins slightly depressed, base rounded to broadly cuneate and slightly asymmetric with margin narrowly recurrent onto petiole, margins sharply serrate with 0.5 - 0.8 mm forward-facing sharply pointed corniculate teeth 0.2 - 0.3 mm wide at their base, apex narrowly acuminate and often slightly curved. Inflorescences axillary, paniculate thyrses, 1 - 2 cm, ca. 25 - 40 - flowered but much reduced in number in fruit, sparsely golden tan-tomentose, with ca. 1.2 x 0.5 mm narrowly triangular acuminate bracts, basal portion of inflorescences before the first branch 1 - 2 mm. Flowers and fruit with a basally articulate 0.5 - 0.6 mm stipe (Fig. 1 C), pedicel 1.0 - 1.5 mm. Flowers 5 - merous; sepals and petals only slightly differentiated, persistent in fruit (Fig. 1 C). Calyx tube broadly obconical, ca. 0.5 x 1 mm, lobes narrowly triangular, 1.0 - 1.2 x 0.5 - 0.6 mm, basally overlapping corolla lobes, margins minutely denticulate, apex acuminate and often distally reflexed. Corolla lobes broadly triangular, 1.0 - 1.2 x 0.5 - 0.7 mm, margins minutely denticulate, apices broadly acute. Stamens 5, at the edge of the floral disc and alternating with corolla lobes. (Only one male plant of Perrottetia taronensis has been seen. It has two remnant undeveloped flower buds with all other flowers already fallen. In Perrottetia the filaments elongate after the male flowers open, so the filament characters in the observed unopened flower buds of P. taronensis are likely not typical of what they would be during anthesis.) Anthers globular, ca. 0.3 x 0.4 mm. Ovary superior, turbinate, ca. 1.2 x 1.0 mm. Fruit a berry, young fruit green but starting to turn red by July and turning purple and becoming fleshy when mature by August, ca. 5 mm in diam. when mature, usually 4 - seeded although occasionally with only 2 or 3 seeds developing, apex emarginate; style ca. 0.2 mm, often deciduous, apically 2 - parted. Seeds brown, 1.0 - 1.5 mm in diam., surface with numerous shallow vertical rugose ridges when dry.	en	Bartholomew, Bruce, Armstrong, Kate E., Li, Rong, Fritsch, Peter W.

6152D7AA6A6950579C0CEE4FF0B7312E.taxon	etymology	Etymology. The specific epithet " Perrottetia taronensis " refers to the Taron River valley in Myanmar. In China this river is named the Dulong Jiang (Dulong River) (Fig. 4). The Taron River flows into the N'Mai Hka (N'Mai River) which joins the Mali Hka (Mali River) forming one of the main northern tributaries of the Ayeyarwady River (Irrawaddy River).	en	Bartholomew, Bruce, Armstrong, Kate E., Li, Rong, Fritsch, Peter W.
