32 REPORT ON TWO BOTANICAL COLLECTIONS FROM 
Leaves digitately trifoliolate ; petiole stout, 4 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, and covered with a 
dense blanket-like tawny tomentum between them ; the lateral pair 31—4 in. long, 25-25 in. 
broad, elliptic, obtuse at both ends, mucronulate, with stout petiolules about 2 lin. long ; 
the terminal leaflet 4} 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, 23-33 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 tomentum, 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 2-4-flowered umbels of a fourth order. Bracts and 
bracteoles suborbicular, about 3-1 lin. diam. Pedicels 12-2 lin. long, stout, not jointed. 
Calyx-limb shortly cupular, 5-toothed ; teeth 4-3 lin. long, deltoid, acute. Bud globose. 
Petals 5, about 2 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 Didymopanax Spruceanum, Seem., 
than any other; but the very thick rigid leaves, rugose above and tomentose beneath, 
at once distinguish it from that and all others. 
SCIADOPHYLLUM UMBELLATUM, N. E. Brown, sp. n. Folia digitata, foliolis 6-8 petiolu- 
latis oblongo-lanceolatis vel oblanceolato-oblongis obtuse acutis basi cuneatis 
supra glabris subtus tomento appresso pallido vestitis. Umbella composit:e, 
longissime pedunculatze, multiflore. Petala ovata, acuta. Fructus immaturus 
5-angularis, compressus. 
Leaves digitately 6-8-foliolate; petiole 4—6 in. long, 11-2 lin. thick, glabrous ; leaflets 
coriaceous, unequal, 23-6 in. long, excluding the 2-7 lin. long petiolules, 1-24 in. broad, 
oblong-lanceolate or oblanceolate-oblong, obtusely pointed at the apex, cuneate at the 
base, entire or very slightly repand, slightly revolute along the margins, glabrous above, 
with a thin layer of pale close tomentum beneath; midrib prominent on both sides, 
stouter beneath; primary lateral veins 9-16 on each side of the midrib, rather slender 
and not very prominent. Umbel compound, 2-3 in. diam., on a peduncle 9-12 in. long, 
23 lin. thick ; rays numerous, unequal, 4-14 in. long, j-1 lin. thick. Bracts minute, 
rounded. Secondary umbels 10-16-flowered. Pedicels 1-12 lin. long. Calyx-limb 
annular, entire or very minutely 5-toothed. Petals 5, acute. Stamens 5, not exceeding 
the petals. Ovary 5-5-celled; style or column of united styles 14 lin, long, minutely 
3—5-fid at the apex. Young fruit deeply 3—5-angled, angles compressed.
