Calochortus striatus, n. sp. 



Corm small, membraneously coated ; subterranean siem 

 usually IO-T2 cm. long, divided at the surface into 2-3 slender 

 erect branches 1-3 dm. high; leaves several 4-25 mm. wide and 

 nearly as long as the stem-branches; the short rigid accuminate 

 bracts hyaline margined; flowers 2-8, umbellate; sepals oblong 

 accuminat,e nearly or quite as long as the petals, the tip at length 

 reflexed; petals broadly obovate-cuneate, centrally apiculate, 

 light purple uniformly striate with darker purple, the lower half 

 sparsely white hairy; gland acutely triangular, densely tufted 

 with ascending whitish hairs; anthers oblong, obtuse, 5 mm. 

 long on filaments of twice the length; immature capsule 4 cm. 

 long. 



In alkaline meadows at Rabbit Springs, alt. 2,700 ft., 

 Mojave Desert, May, 1882, ij^2 Parish, (type); June, 1884; 

 June, 1901, j,ooo Parish. Also at Cushenberry Springs in the 

 same region. The original collection was distributed as C. 

 flexiwsiis. The so-called "meadows" are barel}^ damp enough to 

 support a sparsh growth of Distichlis. The accompanying plants 

 are three species of Cleoinella, Hoitttuynia Calif ornica, Cniciis 

 Mohavensis.^ and one or two Atriplicis. To find a Calochortus 

 growing in such an alkaline association is certainly remarkable.

 / Calochortus Palmeri, Watson, 1. c. 266. Purdy, 1. c. 144. 



Corymb membraneousl}' coated, oblong stems slender, erect, 

 3-5 dm. high, bulbiferous at base; leaves narrow and short; 

 bracts linear; sepals oblong, shortly accuminate, with a purple 

 stain at base, thetip at length recurved; petals rather narrowly 

 obovate-cuneate, about 2 cm. high, white to very light purple, 

 the claw brown; gland large, undefined, short, hairy, and with a 

 few surrounding scattering hairs; "capsule very narrow, an inch 

 long, or more." 



The type was collected "near the Mojave River, n. 527, 

 Palmer, 1876." It was almost certainly at the point where the 

 Mojave River makes its exit from the San Bernardino Moun- 

 tains; a place then known as Holton's ranch, afterwards as 

 Borcham's, and now as Los Flores Rancho. The altitude is 

 about 3,500 feet. The above characters, except for the capsule, 

 which is quoted from Watson, is drawn from specimens collected
