tipartite segments distant subfalcate acute irregularly toothed, terminal 

 lobe 3-fid; stems 2-3 from each stock, leafless below but with 2 short- 

 petioled apical floral leaves conformable to tlie radical usually subop- 

 posite but sometimes separated by an internode ; apex of stem support- 

 ing a fascicle of long-pedicelled flowers and when the second leaf is 

 remote from the highest with a second fascicle in its axil; sepals 

 small ovate acute puberulous; flowers medium yellow, pedicels brac- 

 teate at the base ; ovary puberulous with soft weak hairs linear, Style 

 long, stigmatic lobes rather large subpatent: capsule narrowly cylindric 

 softly puberulous: seeds small numerous ovate, crested.

Rootstock 1-1 1 /2 in. long, heads 1/4 in. diam. ; stems 4-15 in. long; radical 

 leaves 12-18 in. long, 3 1 /2-Q in. wide, segments 6-7-jugate, pétioles 3-4 in. 

 long; floral 4-8 in. long, 3-5 in. wide, segments 6-7-jugate, terminal lobe 

 very large 4 l J2 in. long, 3 1 /2 in. wide ; sepals 1/2 in. long, buds 1/4 in. diam. ; 

 flowers 1 7* i Q across, pedicels 3-4 in. long, bracts acuminate 1/2 in. long; cap- 

 sule (including style 1/3 in. long) 2-3 in. long, 1/6-1/5 in. diam. 



This interesting species has the foliage of C. sutchnense to which it 

 is obviously very closely related; it difiers however in fruit. In the 

 disposition of its leaves this most resembles the American C. diphyllum; 

 at the same time the occasional séparation of the apical floral leaves, 

 with a corresponding subdivision of the terminal fascicle of pedicels 

 into two, shows that we hâve hère essentially the same arrangement as 

 in C. majus only with sessile instead of peduncled fascicles. 



4. Chelidonium diphyllum Michx; glaucous puberulous, root- 

 stock slender fibrous ; radical leaves few very long-petioled pinnatisect 

 segments distant rounded obtusely lobed, terminal lobe 3-fid; stems 

 leafless below but with 2, less often 3, subopposite apical petioled floral 

 leaves similar to the radical; apex of stem supporting a fascicle of long- 

 pedicelled flowers; sepals large ovate puberulous; flowers large yellow 

 pedicels bracteate at the base; ovary puberulous with soft weak hairs 

 ovate 4-(rarely 3-, very rarely 2-) valved, style long, stigmatic lobes 

 small erect; capsule ovate, softly puberulous; seeds small numerous 

 crested.
