ll-Ji M. PRA1N. REVISION OF THE GENUS CHELIDONIUM. 581 



Bpecies of Stylophorum. The only différence between the sections Eu- 

 chelidonium (C. majm) and Stylophorum is the présence of an internode 

 between the Leafand theaggregate ofbracteate pedicels constituting the 

 inflorescence proper in tho first named, and the absence of this inter- 

 node in the second.

2. Chelidonium sutchuense Franch.: glaucous puberulous; 

 rootstock slender fibrous; radical leaves few long-petiolcd pinnatitid 

 segments distant suhfalcate acute irregularly toothed, terminal lobe 

 3-fid; stems with 4-7 short-petioled alternate cauline leaves and 2 

 subopposite almost sessile apical floral ail conformable to the radical; 

 apex of stem supporting a fascicle of long pedicelled flowers; sepals 

 medium ovate acute puberulous: flowers large yellow, pedicels brac- 

 teate at base; ovary puberulous with soft weak hairs ovate-oblong, 

 style long, stigmatic lobes small erect ; capsule narrowly ovate-oblong 

 acute, softly puberulous: seeds blackish ovate, crested.

Rootstock i l /a in. long, heads 1/6 in. wide; stems 12-13 in. long; radical 

 leaves 11 in. long, 3 l /2 in. wide, pétioles 3 in. long, segments 4-o-jugate : 

 cauline 9 in. long, 3 l /» in. wide, pétioles 1 in. long, segmenU 3-4-jugate;

 in. acuminate; capsule (including style 14 in.) 3/4-1 in. long, 1,4 in. wide. 



In foliage this closely resembles C. lasiocarpum Oliv., which species 



moreover occurs in the same locality : tho fruit however is quite dif- 

 férent and is in fact hardly distinguishable from that of tho North 

 American C. diphyllum though it does not. as in that species. appear to 

 hâve ever more than two placentas. So far as its fruit goes this is almost 

 exactly intermediate between thèse two species and indicates very 

 clearly the necessity of treating them as congeneric. Its scattered stem 

 leaves as the other band make it intermediate between both species and 

 C. majiis, and indicate the necessity ofmerging all three in Chelidonium. 



3. Chelidonium lasiocarpum Oliv. ; glaucous puberulous: 

 rootstock rather slender tufted: radical leaves few long-petioled piuna-
