352 LVIII. ARALIACEtE [Arabia 



Japan. A prickly shrub or small tree, 1. digitate, leaflets 3-5, sinuate-dentate, blade 

 1-3, pet. J- J in. long. Umbels many-fid or in short racemose panicles, pedicels numerous, 

 J-l in. long,- not articulate. Petals 4-5, valvate, ovary 2-celled, styles 2. Albumen 

 uniform. 



7. HETEROPANAX, Seem. ; Fl. Brit. Ind. ii. 734. 



H. fragrans, Seem, (the only species), Vern. Tarlcl, Dinha, N.-W. Prov. ; 

 Tachanza, Burm. 



A small glabrous soft-wooded deciduous tree, attaining 60 ft. in Burma. L. 

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

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

 the £ fl. sessile or nearly so, in globose heads, the bisexual fl. in umbels usually 

 at the ends of racemes. Pedicels not articulate, petals 5, valvate, ovary 2-celled, 

 styles 2, distinct, filiform. Fr. laterally compressed, \ in. diam., endocarp 

 crustaceous, albumen ruminate. 



Subhimalayan tract from the Jumna eastwards. Assam, Khasi hills, Chittagong. 

 Andamans, Burma. Fl. Dec.-Feb. China, Tonkin, Java. The 1. resemble those of 

 Oroxyhim indicum. 



8. BRASSAIOPSIS, Dene. & Planck ; Fl. Brit. Ind. ii. 735. 



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

 Inflorescence and calyx stellately hairy while young, pedicels not articulate, 

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

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

 2-celled, Styles united. Fr. often 1-seeded, albumen in some species ruminated. 

 Species 11. India, Malay Archipelago. 



A. Leaves undivided. 



1. B. simplicifolia, C. B. Clarke. Mishmi hills. Braiachlets prickly, leaves ovate- 

 lanceolate, serrate, glabrous, penninerved, the lowest pair basal, blade 8, pet. 1J 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, young shoots 

 stellate-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. Sikkim, 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 F. Fl. i. 537. Sikkim 2-4,000 ft. Chittagong. Andamans, Malay 

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

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

 possibly not specifically distinct. In Brassaiopsis as well as in other Araliacecz the 

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

 to be untenable. 5. B. mitis, C. B. Clarke, Moqchini, Nep. Sikkim 6-8,000 ft., common about 

 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. hispida, 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 stellate-tomentose. 7. B. GrifBtMi, C. B. Clarke. Assam. Imperfectly 

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

 distinctly toothed, petals reflexed after flowering, disk conical. 



C. Leaves digitate. 



8. B. speciosa, Dene. & Planch. Ver. Baw, Burm. 



A small simple-stemmed tree, prickles on the stem and often also on the
