 tripinnate, 2-4 ft. long, leaflets ovate, elliptic or elliptic-lanceolate, 3-7 in. 

 long. Fl. yellow, fragrant, polygamous, tomentose, in elongate panicled racemes,

8. BRASSAIOPSIS, Dene. & Planch. ; PL Brit. Ind. ii. 735. 



Trees or large shrubs, usually prickly, 1. simple, palmate or digitate. 

 Inflorescence and calyx stellatel}'- hairy while young, pedicels not articulate, 

 bracteate at base. Bracts on ramifications of inflorescence persistent. PI. 

 pentamerous, often polygamous, pedicels not articulate, petals valvate. Ovary 

 2-celled, styles united. Pr. often 1-seeded, albumen in some species ruminated. 

 Species 11. India, Malay Archipelago. 



A. Leaves imdivided. 



1. B. simplicifolia, 0. B. Clarke. Mishmi hills. Branchlets prickly, leaves ovate- 

 lanceolate, serrate, glabrous, penninerved, the lowest pair basal, blade 8, pet. IJ in. long 



2. B. Hainla, Seem. Sikkim 1-5,000 ft. Bhutan. Naga hills, Manipur. Yunnan. A small 

 evergreen much branched and sometimes scandent tree, branches prickly, yoxxng shoots 

 steliate-tomentose. L. divided less than half-way down into triangular cuspidate seg- 

 ments, blade 5-8, pet. 5-10 in. long, basal nerves 5-7. Fr. generally 2-seeded, J in. diam. 



3. B. alpina, C. B. Clarke. Sikknn, 10-11,000 ft. Branchlets, leaves and inflorescence 

 densely villous with tawny tomentum. L. cordate, serrate, often slightly tricuspidate, 

 blade 3-5, pet. 5-9 in. long, basal nerves 3-5. C. B. Clarke thinks that this may possibly 

 be a high level form of 2. 



B. Leaves palmatifid, divided half-way down or more. 



4. B. palmata, Kurz P. PL i. 587. Sikkim 2-4,000 ft. Cliittagong. Andamans, Malay 

 Penins. A small sparingly branched tree, young shoots with rusty scurfy tomentum, 

 1. cordate, deeply 5-7-iid, blade 5-10, petiole 5-11 in. long. Closely allied to 2, and 

 possibly not specifically distinct. In Brassmopsis as well as in other Araliacem the 

 leaves vary considerably, and the 3 sections here accepted may on further study prove 

 to be untenable. 5. B. mitis, C. B. Clarke, Moncli ini, Fep. Sikkim 6-8,000 ft., common aboixt 

 Darjeeling. A small upright deciduous tree, branches once or twice forked, leaves only 

 near the tops of branches. L. deeply 9-13-fid, blade 6-18, pet. 6-24 in. long, basal n. 9-13. 

 L. slightly hairy beneath, petiole with soft bristles near the end. Umbels many-fld. in 

 long panicles below the tuft of leaves. 6. B. Mspida, Seem. Sikkim 5-7,000 ft. Mishmi 

 hills. Yunnan. A small prickly tree, 1. deeply 7-9-fid, segments oblong, spinulose- 

 serrate, blade 6-18 in. long, pet. sheathing at base, as long as blade. Calyx-tube and 

 pedicels densely steliate-tomentose. 7. B. GriffitMi, C. B. Clarke. Assam. Imperfectly 

 known, apparently unarmed, 1. very large, almost glabrous, thickly membranous. Calyx 

 distinctly toothed, petals refiexed after flowering, disk conical. 



0. Leaves digitate.
