Throughout the hotter partB of India, as far to the N.W. as Qaewhal ; and in Ceyloit. 

 — DiSTKiB. China, Java. 



But distinguished from B. sensitivum by the graceful habit, slender peduncles, and 

 small flowers with the capsule not much overtopped by the sepals. The seeds vary in 

 amount of furrowing and luberoles exactly as in S. sensitivum. The following three 

 varieties are regarded as species by Mr. Edgeworth : — 



Vae. 1. Meinwardiii proper ; seeis sphaXly fnrrawed. 0. Eeinwardtii, ^cc. in port. 

 0. sensitiva, Linn. Herb, in part ; Wall. Cat. 4343 B 2. 



Vae. 2. nervioides ; seeds deeply furrowed and tubercled. 



Var, 3. Metziana; seeds turbinate 5-7 furrowed tuberculate. — To which should be 

 added — 



Vak. 4. yroeilenta ; seeds tubercled not furrowed. 



** Stem imially branched in a proliferous manner. Leaflets usually cus- 

 pidate or acuminate; the terminal pair generally shorter ihan the rest. 



5. Bi nudum, Arn. in Nov. Act. Acad. Gees, xviii. 326; stem tall 

 simple or branched, leaflets 15-30 pairs linear-oblong obliquely abruptly 

 cuspidate equal at the base, midrib straight, nerves close-set, pedicels 

 equalling or exceeding the sepals, seeds tubercled not furrowed. Wight 

 III. i. 161. 



Ceylon, Central Province, alt. 4^6000 ft. 



Apparently annual. Stem 6-18 in., sometimes as stout as a goose-quill, often umbel- 

 lately branched. Leaves 2-3 in., racbis tomentose; leaflets ^ in., glabrous, margins 

 thickened, base truncate. Pedurtdes slender, pubescent ; pedicels pilose. Sepals ^ in., 

 scarcely exceeding the globose capsule. 



6. B. proUferum, Aiti. in Nov. Act. Acad. Goes, xviii. 327; stem slender 

 prostrate copiously dichotomously branched from a woody stock, leaves 

 short, leaflets very small 5-10-pairs oblong obliquely cuspidate, midrib 

 nearly straight, base equal, peduncles very short usually 1-flowered, seeds 

 tubercled not furrowed. Wight III. i. 162. 



Ceylon, alt. 6000 ft., Walker, Gardner, &o. 



A remarkable species, easily recognised by its excessively branched prostrate habit, 

 slender branches, minute leaflets, and solitary, rarely geminate flowers. Branches and 

 peduncles pulescent. Leaves rarely 1 in., in whorls ; leaflets J in. long, usually gla- 

 lirous aliove ; nerves oblique, slender. Peduncles much shorter than the leaves and than 

 the very slender pedicels. Sepals hairy, about as long as the leaflets. — I identify this 

 \'ith Amott's plant on the faith of two specimens thus ticketed by himself in Wight's 

 Herbarium, though Arnott describes the umbel as 2-5-flowered, and the leaflets as 

 jiilose above, and does not allude to the remarkable smallness of the foliage ; whence I 

 su.spect that he had both this and the following under his eye. * 



7. B. intermedium, Wight lU. i. 162 ; branches very numerous from a 

 stout woody rootstock slender dichotomously branched, leaflets 16-20 

 pairs linear-oblong abruptly cuspidate, midrib somewhat arched, base equal, 

 peduncles usually exceeding the leaves several-flowered. 



Ceyi.on, Wallcer. 



A much larger i)lant than B . proUferum, of a very different habit, having long 

 arching bi-anches arising from a woody stock as thick as the finger. Leaves 2 in. long ; 

 leaflets \-\ in., glabrous or pilose above, margins sometimes ciliate, nerves close-set, 

 oblique; petiole ciliate with long hairs. Flowers three times as large as in B. proU- 

 ferum. — ^1 have identified this by specimens in Wight's Herbarium; which contains a
