586 LX[i. OXAGRACEJI. (.0- B. Clarke.) \_Epilolium. 



tinguished from E. roseum var. indicum by its greater glabrousness and obtuser 

 lea res. 



VAR. minimum ; stem 34 in. with 1-2 capsules, flowers and leaves very small. 

 This in general appearance coincides with E, alpinum, Linn, but the seeds are 

 broadly obovoid not at all elongate upwards. 



10. E. orig-anifolium, Lmnk. Diet. ii. 376 ; middle cauline leaves 

 opposite sessile or very shortly petioled ovate or ovate-oblong-, seeds elongate 

 narrow obovoid somewhat narrowed at the top. DC. Prodr. iii. 41 ; Boiss. Ft. 

 Orient, ii. 750. 



ALPINE HIMALAYA, alt. 9000-14,000 ft. ; from KASHMIR to SIKKIM. DISTRIB. 

 Northern cool temperate and Arctic zone. 



Greatly varying in the size of stem, leaves and flowers. Stem usually 8 in., some- 

 times 2 ft., usually with 2 hairy lines, sometimes exactly terete and uniformly pubes- 

 cent. Middle cauline leaves usually 1 in., sessile, ovate, pubescent only on the 

 somewhat raised nerves beneath ; but the leaves are sometimes petioled, nearly 3 in., 

 pubescent, sometimes ^ in. sessile glabrous. Flowers usually few, approximated 

 towards the ends of the branches. Petals usually less than ^ in. ; in the var. E. Ba- 

 lanscB Boiss. (collected by J. D. H. also in Sikkim) the petals exceed | in. Capsule 

 1| 3 in., peduncle also variable in length. Seed minutely puncticulate, coma 

 fulvous. 



VAR. villosum ; stem villous, leaves f-1 in. villous over both surfaces sessile ovate. 

 Sikkim, alt. 10,000-12,000 ft. ; Latong, J. D. H. EpilobiumNo. 7, Herb. Ind. Or. 

 H. f. $~ T. Stems 4-8 in., little divided. Leaves acute, nearly all opposite. Flowers 

 few, approximated, not large. Stigma clavate. Capsule half-ripe, seeds not seen. A 

 remarkable plant. The lowest leaves are small thick obovate rounded glabrous, 

 greatly resembling the similar leaves in E. origanifolium. 



11. B. alpinum, Linn. ; DC. Prodr. iii. 41 ; stems weak somewhat pu- 

 bescent, middle cauline leaves opposite small subsessile narrow-elliptic glabrous 

 or pubescent on the nerves beneath, flowers few towards the end of the 

 branches, Boiss. Fl Orient, ii. 750. 



SIKKIM; alt. 12,000 ft.; Lachen, J. D. H.; Jongri, 0. B. Clarke. 



Stems 2-10 in., slender, scarcely divided. Middle cauline leaves \-\ in., denticu- 

 late obscurely or prominently, scarcely acute. Capsule 1|- in", peduncle \-^ in, Seeds 

 minutely papillose, narrowly ellipsoid, little narrowed at the summit ; coma silky, 

 white. This is perhaps E. alpinum of Boissier but is not the ordinary European plant 

 which has a beaked seed as described in Hk. f. Student's British Flora, p. 145 ; the 

 European examples also have a fulvous coma. 



ft Stem clearly quadrangular. 



12. X2. tetragonum, Linn. DC. Prodr. iii. 43; middle cauline leaves 

 mostly opposite oblong- or narrow-elliptic glabrous but with crisped hair on the 

 raised nerves beneath usually denticulate-serrulate rarely acute. Boiss. Fl. 

 Orient, ii. 748. E. brevifolium, Don Prodr. 222. 



SIKKIM, alt. 5000-12,000 ft., very common. KHASII MTS., alt, 4000-6500 ft., 

 common. DISTRIB. Cold and cool temperate zones of both hemispheres, and at 

 temperate elevations on mountains in the warmer zones. 



Stems 1-3 ft., with crisped pubescence on the four angles. Middle cauline leaves 

 opposite, -|-2 in., usually sessile, but in some Indian examples distinctly petioled, nerves 

 beneath raised often very prominently, above much impressed. Flowers rose or pur- 

 ple, rather small. Capsule 1^-2 in. ; peduncle \- ^ in. Seeds narrowly elliptic, not 

 narrowed at the summit, very little narrowed at the base, minutely papillose, 

 coma fulvous.
