BOT.-VOL. II.] PURDY-CALOCHORTUS. 145 



The writer has never seen a specimen which conformed 

 to the description: all of those seen from Southern Cali- 

 fornia collections were either C. invenustus or C. splendens 

 var. montanus.

A foot or two high, general habit as in C. splendens; stem bulbiferous at 

 base; sepals broadly ovate-lanceolate, acute, a little shorter than petals, 

 greenish, spotted dark purple on claw; petals cuneate, longer than wide, 

 rounded above, narrowing abruptly to a short narrow claw; color from white 

 tinged with lilac, to lilac purple, with a large ovate purplish-maroon mark, 

 the apex covering claw and the rounded end above gland; gland oblong, 

 densely matted with short agglutinated hairs, a few scattering hairs around 

 and above; filaments slender, about four times as long as the yellowish, 

 oblong-obtuse anthers; capsule oblong, rounding at both ends. 



Described from specimens taken near Los Angeles, 

 California. 



"Santa Catalina Island." [California.] 



C. catalincB is found from Los Angeles and San Bernar- 

 dino along the coast to Santa Barbara, and on all the islands 

 along the coast. It is one of the least variable and best 

 marked of all the Mariposas. The oblong capsule is a 

 distinctive feature, while the peculiar ovate mark on the 

 petals is equally characteristic. 



The species was first described by Watson from a plant 

 in the capsule, the specimens having been collected on 

 Santa Catalina Island. Later, he described the same spe- 

 cies, under the name of C. lyoni, from flowers collected at 

 Los Angeles and Newhall by Dr. Asa Gray and W. S. 

 Lyon. C. lyoni also grows on Santa Catalina Island, and 

 there is no doubt of its identity with C. catalincB. In an 

 able article in "Erythea," Dr. Davidson of Los Angeles 

 shows that the two species are the same.
