538 Piper : Notes on Calochortus 



mm. long ; scale about one third as broad as the petal at its 

 place of insertion, nearly semicircular, but little incised : stamens 

 one third as long as petals, the acuminate anthers as long as the 

 flattened filaments : style short : capsules nodding, orbicular when 

 mature, 1.5 cm. long. 



This species is nearer true C. clegans Pursh than any other 

 Californian species. It is most easily distinguished by the charac- 

 ter of the scale, which in C. elegans is half as wide as the petal or 

 more, and deeply laciniate into many narrow segments. 



The original specimens of Wood are very slender, but later 

 collections show that the species becomes at least as large as C. 

 clegans. The species seems to be rare and is not accounted for 

 apparently in any recent treatment of the genus. Only the fol- 

 lowing specimens have been seen :

11 : 195. 1906 



Bulbs ovate, 2-3 cm. long, the outer coats dark : stems flex- 

 uous, erect, 1 5-20 cm. high, usually exceeded by the solitary leaf, 

 1-3-flowered: leaf linear-lanceolate, acuminate, 3-8 mm. wide, 

 paler beneath : bracts lanceolate, long-acuminate, 2-3 cm. long : 

 sepals lance-ovate, acuminate, somewhat scarious on the margins, 

 1.5-2.5 cm. long, 6-9-nerved, the base strongly arched, forming a 

 shallow pit inside, this marked by a purple spot : petals cream- 

 colored, purplish at base, obovate or rhombic-orbicular, 2-3 cm. 

 long, slightly erose at margin, sparsely villous over the upper 

 face above the striate, minutely puberulent gland, excepting a 

 narrow portion near the apex ; scale narrow, entire, extending in 

 a gentle curve nearly across the petal and covered with long 

 retrorse hairs : filaments broadly wing-margined, equaling the 

 long-beaked anthers: capsules nodding, narrowly elliptical, rather 

 acutish at each end, 2-3 cm. long, beaked by a style 1-2 cm. 

 long. 



A subalpine species, closely allied to C. Purdyi Eastwood, 

 which differs in having thinner sepals lacking the pit at base ;
