Gossia aphthosa subsp. longipedunculata N. Snow & Munzinger , subsp. nov. ( Figs 5 View FIG ; 13E-I View FIG )

Differing from Gossia aphthosa subsp. austro-orientalis N. Snow & K. Gandhi, subsp. nov. by its somewhat longer inflorescences (5-8 cm vs less than 6 cm in G. a. subsp. austro-orientalis N. Snow & K. Gandhi, subsp. nov.), more stiffly coriaceous leaf blades, and different eco-geography. Also resembling Gossia colnettiana , but that species has rounded to cuneate leaf bases (vs cordate-clasping leaf bases in G. a. subsp. austro-orientalis N. Snow & K. Gandhi, subsp. nov.).

REPRESENTATIVE HERBARIUM SPECIMEN. — P00354535.

ETYMOLOGY. — In reference to the relatively long peduncles occurring on many specimens.

DISTRIBUTION, HABITAT AND PHENOLOGY. — Central Grande Terre, near Ponérihouen, Haute Tchamba, and Haute vallée de l’Amoa ( Fig. 5 View FIG ) in humid forests on volcanic-sedimentary soils, 300- 900 m. Flowering confirmed August through April; fruiting October and November.

REMARKS

This subspecies is recognized most easily by its large (8-12 mm) petals. (An unpublished manuscript name of mine for some specimens was Gossia “grandiflora”.) The inflorescences often are densely fasciculate in leaf axils or on branches and stems. It can also resemble G. kuakuensis , but that species has larger flowers and a slightly ribbed to rugose hypanthium.
