32 EEPOET ON TWO BOTANICAL COLLECTIONS FROM 



Leaves digitately trifoliolate ; petiole stout, j in. thick, tomentose, broken in the only 

 specimen seen and about 3^ in. long ; leaflets rigidly coriaceous, above glabrous and 

 rugose, with a narrow prominent midrib and impressed veins and veinlets, beneath 

 tomentose on the very stout prominent midrib and the primary veins, arid covered with a 

 dense blanket-like tawny tomenturn between them ; the lateral pair 3J-4 in. long, 2J-2f in. 

 broad, elliptic, obtuse at both ends, mucronulate, with stout petiolules about 2 lin. long ; 

 the terminal leaflet 4f in. long, 2| in. broad, elliptic-oblong, slightly emarginate at the 

 obtuse apex, mucronulate, with a stout petiole 4 lin. long. Umbel very compound, 6-8- 

 rayed, many -flowered, 2f-3A in. diam., with a stout, more or less flattened peduncle 4-7 in. 

 long, 2-3 lin. thick, everywhere, to the outside of the petals, densely covered with a 

 tawny tomenturn, becoming greyish with age. Secondary umbels 6-7-rayed, some of the 

 rays bearing a single flower, others dividing into tertiary umbels, some of which again 

 divide in a similar manner, forming 2- 1-flowered umbels of a fourth order. Bracts and 

 bracteoles suborbicular, about J-l lin. diam. Pedicels li-2 lin. long, stout, not jointed. 

 Calyx-limb shortly cupular, 5-toothed ; teeth J-£ lin. long, deltoid, acute. Bud globose. 

 Petals 5, about f lin. long, and nearly as broad, deltoid-ovate, acute, rather thick, 

 glabrous within. Stamens 5, not longer than the petals. Ovary 2-celled; styles 2, 

 somewhat flattened, divergent in young fruit, which is suborbicular in outline and 

 compressed.

A most distinct species, in general habit more like Didymopcmax Spruceamm, Seem., 

 than any other ; but the very thick rigid leaves, rugose above and tomentose beneath, 

 at once distinguish it from that and all others.
