nent, furrows usually 3-vittate Ceylon. Stem usually simple, erect, laxly corymbose 

 above, cauline leaves subacute, It is the existence of this var. that has led to the 

 referring the South Indian species to B. falcatum. This Ceylon plant differs from 

 the Himalayan B. falcatum not only in the shortened fruit but in the invariable pre- 

 sence of 4-5 bracts. 



9. B. distichophyllum, W. fy A. Prodr. 370 ; lower cauline leaves 

 distichous bases closely imbricate sheathing, upper linear broadest at the base, 

 fruit elliptic, ridges distinct, furrows generally 1-vittate. Wight Ic. t. 1006. 



NILGHIEI MTS., alt. 7000 ft. ; Wight, &c. 



. Stem 4-14 in., slender, erect ; otherwise closely resembling B. mucronatum from 

 which it differs chiefly in the very small fruits (i in.). The lower distichous leaves 

 are in the typical examples very closely packed, 12-16 in the space of 1 in. ; but 

 when these are absent it is difficult to distinguish from small examples of B. mucro- 

 natutn. 



10. B. long'icaule, Wall. Cat. 557 ; lower cauline leaves linear or lan- 

 ceolate acute upper often wider at the base, bracteoles 5-8 elliptic-acuminate 

 foliaceous longer than the flowering umbellule, fruit oblong, ridges subalate, 

 furrows 3-vittate. DC. Prodr. iv. 131. B. rupestre, Edyw. in Trans. Linn. 

 Soc. xx. 52. 



HIMALAYA, alt. 8-13,000 ft. ; from KASHMIR to SIKZIM; common. 



Stem 8-24 in., erect, corymbose upwards ; sometimes branching from the root. 

 Leaves verj r variable ; in the Wallichian type narrow-linear acute, the uppermost (and 

 the bracts) little wider, hardly broader at the base, transverse nerves not prominent ; 

 in other examples upper leaves (as the bracts) ovate, acute, with very prominent 

 secondary nerves. Bracts 1-3 ; bracteoles 5-8, very prominent, with reticulating 

 nerves, often longer than the fruiting umbellule ; rays 3-8, l-2 in., somewhat stout, 

 striate. Petals and disc usually black. Fruit ^-^ in. 



VAR. 1. himalensis, Klotzsch in Keis. Pr. Waldem. Bot. 146, t. 51 (sp.); upper 

 leaves ovate-lanceolate base amplexicaul ovate almost cordate, bracteoles 8-10 very 

 brpad imbricate. Kashmir, alt. 12,000 ft., frequent. Connected by imperceptible 

 gradations with the Eastern plant. 



VAR. 2. DalTiousieana ; upper leaves and bracts ovate-lanceolate narrowed at the 

 base, petals yellow, disc brown, fruit stongly ridged hardly winged usually thrice as 

 long as the pedicel. Dalhousie and Dhurmsala, alt. 8000-12,000 ft.; plentiful, 

 C. B. Clarke. Stems 4-8 in., sometimes erect 24 in., much divided or simple, corym- 

 bose at the top. Upper leaves and bracts with the transverse nerves obscure. 

 Bracteoles smaller than in typical B. longicaule, less acuminate, and much less 

 foliaceous, the transverse nerves far less prominent. The true affinity of this form 

 is very doubtful : it differs from B. Candollii in the cauline leaves being narrower 

 with obscure secondary nerves, and by having all the leaves more acute : from B. 

 tenue in the acute leaves, stout rays of the umbel, and much stronger umbellules. 



VAR. 3. stricta ; stems 12-15 in. usually simple terminated by a strict umbel, bracts 

 and bracteoles elliptic- oblong hardly acute pendent in fruit. Sikkim ; Jongri, alt. 

 12, 000-13,000 ft., C. B. Clarke. Stem very erect. Lower leaves 'linear., upper rather 

 broader, all narrowed at the base. Bracts several, sometimes nearly 2 in. ; bracteoles 

 orbicular or oblong, sometimes ^ in., longer than the fruiting umbellule ; rays of the 

 umbel stout, ascending not divaricate. Fruit longer than in any form of B. lovgicaule, 

 sometimes | in. This is almost surely allied to Var. Dalhousieana : but it may be 

 doubted whether it should be attached to B. longicaule, Wall. 



11. B. tenue, Don Prodr. 182 ; upper leaves linear-oblong subobtuse 

 mucronate narrowed at the base, bracts and bracteoles not prominent, primary 

 rays of the umbel slender, fruit T \- in., ridges prominent, furrows 1-vittate.
