5. Uncaria ferrea, DO. Prod. IV. 348. Young branches much 

 thinner than a goose-quill, minutely but deciduously rusty-pubescent, 

 the bark dark-coloured. Leaves membranous, ovate or ovate-lanceolate, 

 shortly and bluntly acuminate, the base rounded or slightly emargin- 

 ate; upper surface dark-coloured when dry, glabrous or with a few 

 scattered deciduous sub-adpressed pale hairs, the midrib and sometimes 

 the main-nerves pubescent ; lower surface pale, minutely reticulate, sub- 

 adpressed rusty-pilose on the midrib and nerves ; main-nerves 7 or 8 

 pairs, curving upwards, depressed on the upper surface like the midrib 

 and prominent on the lower ; length 2*5 to 3*25 in.; breadth 1'35 to 2 

 in. ; petioles '1 to '2 in., tomentose ; stipules broadly semilunar, deeply 

 two-lobed, adpressed rusty-pilose, '25 in. long. Peduncles much longer 

 than the petioles, but shorter than the leaves, lengthening in fruit, com- 

 pressed, densely ferruginous-tomentose'; bracteate above the middle; 

 heads about 1*5 to 2 in. in diam. when in flower, and 2 to 3 in. when in 

 fruit. Calyx shortly stalked, *25 in. long, silky; the tube narrowly 

 oblong-ovoid ; the limb deeply divided into filiform lobes longer than 

 the tube. Corolla about twice as long as the calyx, glabrous ; its tube 

 very narrowly cylindric, angled: the lobes of the mouth broadly oblong 

 or obovoid, very obtuse. Capsules double-fusiform, ridged, pubescent, *5 

 to *75 in. long, crowned by the filiform calyx-lobes, tapered into slender 

 pedicels as long as themselves. Hook. fil. Fl. Br. Ind. III. 33; Havil.
