 hairs. Leaves exactly cordate, acuminate, over 3 in. long, by barely 

 2^ in. broad, adpressed strigose on both sides, rough and dark green 

 above, a little paler with dark reticulated veins beneath ; petiole 1-2 in.

 spreading yellow hairs. Flowers in dense dark heads on stiff distant 

 peduncles 1-2^ in. long, grey-hirsute, especially at the apex; bracts small. 

 Sepals scarcely larger than and similar to the bracts, lanceolate, acute, 

 hairy, 5 lin. long, 1-1 A lin. broad. Corolla funnel-shaped, glabrous,

52. I. lasiophylla, Hallier f. in Bull. Soc. Bot. Belg. xxxvii. 94, 

 and in Engl. Jahrb. xxviii. 32. A climbing pubescent herb ; branches 

 terete, woody, which like the petioles and peduncles are hoary- or 

 yellowish-puberulous. Leaves subcordate, acuminate, 2 in. long, 1^ in. 

 broad, rather densely covered on the dull green upper surface with an 

 adpressed yellowish somewhat silky pubescence, and with a dense hoary 

 somewhat silky pubescence beneath ; petiole 9 lin. long. Flowers 

 small, sessile, crowded in pecluncled axillary hoary pubescent heads ; 

 peduncles about 1 in. long ; heads about 1 in. in diam. ; bracts ovate- 

 lanceolate, acute, scarcely exceeding the sepals, 6 lin. long, rather densely 

 hoary pubescent on the margin, laxly so on the back. Sepals like the 

 bracts and scarcely smaller. Corolla funnel-shaped, 1 in. long; mid-

" In the character of the indumentum and the form of the flower-heads and their 

 bracts this species seems nearest to /. clirysochadia, but is easily distinguished by 

 its finer, softer, greyer hairs, which are denser on the under side of the leaf, and 

 also by the smaller corolla." — Hallier f ., I.e. 



53. I. galactorrhea, Hallier f. in Engl. Jahrb. xxviii. 33. A 

 climbing tomentose herb. Branches herbaceous, subco in pressed,

 and longer scattered spreading hairs. Leaves long-petioled, cordate, 

 acuminate, 2| in. long, 2i in. broad, dull dark green above, and clothed 

 with a somewhat hoary adpressed pubescence, and with dense white 

 arachnoid hairs beneath ; nerves light yellowish-green ; petiole 1^ in.
