REPRESENTATIVE HERBARIUM SPECIMEN. — P02089875.
DESCRIPTION
Shrubs or trees
3- 8 m.
Branchlets
Terete; internodes> 5 mm.
Leaves
Coriaceous, 2 per node; petioles 2.5-4 mm, terete; blades 2.0- 4.5(-4.8) × 0.8-1.7(-2.4) cm, narrowly elliptic to narrowly obovate, base narrowly cuneate, surface flat, margin flat, apex obtuse, midnerve above sulcate proximally becoming flush apically, secondary veins not visible above, oil glands of lower surface dense but indistinct.
Inflorescence
Of monads or 3-flowered cymes, axillary, pedicels to 4.5 cm; extrafloral bracts absent.
Bracteoles
c. 2 mm, narrowly ovate to ovate, glabrous.
Hypanthium
2.8-3.2 × c. 3 mm, urceolate, surface smooth, glabrous; ovary apex glabrous.
Calyx
Lobes 4 (5 occasionally), 1-2 mm, broadly ovate to rounded, glabrous above and below, green.
Petals
Not seen.
Filaments
3-4.5 mm; anther sacs 0.6-0.8 mm.
Style
4.5-5 mm, hairy to near apex.
Fruits
5-9 × 6-11 mm, subglobular to globular, base rounded, green becoming reddish then bluish-black; seeds 2-3, irregularly hemispherical.
REMARKS
Within Gossia the species is distinguished by leaves that are nearly all 4 cm or less long and distinctly yellowish-green, with dark maroon petioles that dry to nearly black.
The species can resemble Gossia vieillardii , but that species has longer leaf blades on average, longer inflorescences, and fruits that often taper distinctly at the base. Additional data from flowering material are needed.
