the transverse veins much depressed on the upper, very prominent on

 •6 in. ; stipules large, rounded, bluntly bifid, sparsely hairy, reflexed, 

 •5 in. long. Heads from 4 to 55 in. in diam. to the ends of the style, on 

 thick, axillary, rusty-pubescent spreading peduncles shorter than the 

 leaves, bearing a whorl of bracts about the middle. Calyx pedicellate 

 about '5 to '8 in. long, densely adpressed-sericeous, the tube short, ovoid ; 

 the limb campanulate, cut into 5 narrowly lanceolate, acute lobes. 

 Corolla villous or sericeous externally ; about twice as long as the calyx ; 

 its tube narrow, cylindric below ; the mouth funnel-shaped and deeply 

 cut into 5 oblong or lanceolate sub-acute, erect lobes. Capsules on 

 slender, rusty stalks ; '5 to 1 in. long, oblong, tapering much to each end ;

This is closely allied to U. pedicellata, Roxb., which see. 



4. Uncaria pedicellata, Roxb. Hort. Beng. 86: Fl. Ind. ed. Carey 

 I. 520; idem, ed. Wall. II. J 28. Like U. sclerophylla, Roxb. in all its 

 parts, but somewhat less robust and much less hairy, the leaves smaller, 

 narrower, never subrotuud, paler and much less bairy beneath ; sometimes 

 even sub-glabrous ; the flowers smaller (only about 1 in. long) ; the 

 lobes of the calyx only '25 in. long ; the tube of the corolla only "4 or 

 '5 in. long, more slender, ferrugineous-silky, rather than pilose or villous ; 

 capsule shorter ('5 to '6 in.) but wider in jDroportion. DC. Prod. IV.

 In all the Provinces, very common. 



This closely resembles U. sclerophylla, lloxb., aud should probably be treated 

 BS a variety of that species. lu a few specimens of this the under surfaces of the 

 leaves between the reticulations are pale-grey and pitted.
