Stem 6-8 in. Radical petioles 7-9 in. segments 1J— 3 in. long, §— J in. wide, lower 

 canline petiole 4 in -> 4 _ 1 i n - below npper sessile leaf; cauline leaf-segments similar 

 to radical but shorter and narrower; bracts \ in., pedicels \ in. ; flowers yellow \ in. 

 long, both outer petals winged. 



Very near to 0. linearioides Maxim, from Kansu and C. Frattii Franch. from 

 Szechuen which resemble each other in racemes and bracts, but have different spars 

 and radical leaves. Of the present species the rootstock has not as yet been collect- 

 ed so that in this respect it cannot be fcomjpared with either. From both, however, it 

 differs in having larger flowers and entire, not laciniate, bracts as well as in having 

 secondary racemes in the axils of the two cauline leaves. Of Indian species it most 

 closely approaches C- polygalina, of which it has much the flowers and which also 

 sometimes has axillary racemes. In C. polygalina however the foliage is quite 

 different, while the cauline leaves are numerous and scattered along the stem. 



9. (6.) CORYDALIS POLYGALINA IS. f. 8f T. 

 Add to description of P. B. I. : — 



Ste7ns simple or with axillary racemes, several from a stoutish rootstock with 

 scaly tip, which emits numerous lateral and basal much elongated narrowly fusiform 

 roots; radical leaves 2-4, long-petioled, 3-sect with always the terminal petiolulate. 

 and occasionally the lateral sessile segments again trisect, lobules all oblong-lanceo- 

 late subequal.

Nearly related to 0. graminea, the characters of which species serve to indicate 

 that this also, in spite of its numerous stem-leaves, is really a member of the 

 same group as the various 2-foliate species referred to in the preceding note. Its 

 most intimate ally is however C. Delavat/i Franch. \_Bull. Soc. Rot. Fr. xxxiii. 393 

 (1886); Plant. Delavay. 46, t 14 b. (1889)] from Yunnan, which differs from this 

 species in having the radical leaves more divided, the crest on the upper petal 

 smaller, and the rootstock Smaller with the roots more slender. No single one of 

 these characters would be sufficient to separate the two plants specifically ; perhaps 

 even their combination only entitles the Yunnan plant to varietal rank. 



10. (7.) CORYDALIS JUNCEA. Wall. 



Add to description of F. B. I. : — 



Radical leaves solitary very long petioled, 3-sect, segments long petioluled again 

 3 sect, lobes sessile 3-partite, ultimate divisions ovate acute to (rarelyj linear-lanceo- 

 late. Seeds brown, arillate, very minutely pitted, occasionally 1-seriate. 



Two very distinct forms of this species occur in Sikkim ; one, exactly like the 

 original plant from Nepal, with rather long slender pedicels much exceeding the 

 bracts and with the petiole of the radical leaf shorter than the stem. This form 

 extends eastward to Phari, Chumbi and Bootan. The other form, confined to Eastern 

 Sikkim and East Nepal has flowers nearly twice as large, pedicels not exceeding the 

 bracts and a radical leaf with petiole as long as the stem. But intermediate forms 

 occur and it is not possible to treat the two forms even as distinct varieties.
