Branches slender. Leaves 2-3 by 131-2] in., red-brown and quite opaque when 
dry; nerves about ő pair, very slender; petiole slender, base rounded, rarely sub- 
cordate. Peduncles 1-1 in., slender, pubescent; bracts orbieular, Heads $ in. diam. ; 
calyx villous, lobes very distinct and almost orbicular; corolla j in., very slender, 
Capsules 1-2 in., twice as long as the filitorm pedicels, rusty-puberulous.—A ve 
distinct species, easily recognised by the broad thin quite glabrous wrinkled (when 
dry) leaves with faint nerves, the 2-fid stipules, small flowers, calyx, and very slender 
capsules. It is one of the 6 species included under Wallieh's U. Gambier (n. 6103), 
and under letter B. is called * U. Gambier et U. ovalifolia, Roxb. Hb. 1824. Ido not 
find the peduncles to be ‘ axillary and terminal, compound,’ as described by Roxburgh. 
11. U. dasyoneura, Korth. Verh. Nat. Gesch. Bot. 169; branches 4- 
angled glabrous, leaves elliptie obtusely acuminate narrowed into the rather 
long petiole shining above, nerves 4-5 pair strong with scattered hairs beneath, 
stipules entire, peduncles short all axillary bracteate about the middle, flowers 
subsessile, calyx shortly 5-toothed, corolla puberulous. Mig. FT. Ind. Bat. ii.

Leaves very uniform, 3-31 by 2-23 in., coriaceous, dark brown, veins very faint 
beneath; petiole 3 in. Peduwncles generally shorter than the petioles; bracts ovate- `

shortly toothed cup; corollas slender. Capsules slender, 1 in., on filiform pedicels.—-

No. 6104 B., from Herb. Finlayson (probably from Siam), has rather more obovate

It is impossible to pronounce, from the descriptions of Rumph and Hunter, what 
they intended by their ‘Gambier.’ I have assumed that Roxburgh’s is the right 
plant, both from his accuracy, and becanse J find that Maingay’s specimens marked 
ag ‘the cultivated plant of commerce’ agree both with Roxburgh’s description and 
h the specimen in Wallich’s Herbarium (6103 A.), which bears Roxburgh’s ticket 
Gambier. Its characters are, in addition to those given above, leaves coriaceous, 
4-5 by 2-24 in., always glabrous beneath except small tufts of hairs in the nerve- 
axils, hardly shining above; stipules entire; peduncles rarely more than an inch 
long; heads 1} in. diam.; calyces tomentose; corollas } in. long with the orbicular 
white silky lobes contrasting strongly when dry with the dark tube, the lobes inside 
bearded towards the base with white hairs (rarely absent); and glabrous fusiform 
capsules 2 in. long on short pedicels. The tuft of white hairs on the corolla-lobes is 
uot represented in Roxburgh's Icones, though described by him,
