forms of C. nitidus which is not bulhiferous at basal leaf, more 

 slender and at once separable by the ribhss anthers. 



Calochortus Watsoni var. ambiguus n. var. 



Stems about 2 dm. long; flowers purple; gland often below the 

 filament tip and broad and about round; anthers mostly longer 

 than the filaments. This much resembles C. fiexuosus but the fil- 

 aments are yellow and the anthers mostly purple, and the base of 

 petals yellow as well as gland except a narrow purple crescent a- 

 bove the gland. The stems are only slightly fiexuous and nearly 

 erect. The ribbed anthers at once separate it from fiexuosiH. Ti.is 

 abounds throughout the Navajo Basin and south to the Pinals in 

 Arizona. Lower Temperate Life Zone. 



Calochortus acuminatus Rydberg is C. macroearpus as to orig- 

 inal description and figure. In his Fl. Col he refers forms of C. 

 Watsoni to it. 



Calochortus speciosus n. sp. 



I propose this name for the most remarkable species in the genus 

 not because I think it is new but because no one seems to know 

 what C. Kennedyi is. If Watson's description of thai species was 

 right then this is new, but he was often inuecurate in the revision 

 of the genus. Stems rarely 2 dm long, mostly stour and short, not 

 bulbiferous, erect, somewhat fiexuous and with short intern odes 

 and several rather rigid and falcate leaves, the root leaf greatly e- 

 longated and the stem leaves much shorter and with broad bases 

 hyaline-margined, the coarse bracts similar and 2-8 cm. long 

 but broader below. Flowers mostly 2 and terminal, on short pe- 

 duncles rarely 5 cm. long and enlarging upwards. Buds about 2 

 cm. long and 1 cm, wide, ovate. Sepals about ovate and apieu- 

 late, nearly olive-colored, with broad hyaline margins, about 2 em. 

 long. Petals when fresh brilliant brick-red, fan-shaped, 3-5 cm. 

 long, erose, the lower £ nearly black with a large laciniate-edged 

 blotch, the very base yellow. Gland very small or obscure, r >und- 

 ish, with very short hairs, mostly nearly black. Hairs of petal on 

 black part few, long, club-shaped. Anthers tapering toward lip, 

 linear, obtuse, purplish, about 1 cm. long, on very short deltoid 

 and yellow filaments about J as lonsr. Style slender, about twice hs 

 long as the large stigma is broad. Pods acuminata, linear-lanceo- 

 late, 2-3 cm. long, deeply lobed. The sepals and petals usually 

 are colored through near base with splotches of purple. Flowers of- 

 ten C cm. wide. Frequent from Chloride Arizona to Congress 

 Junction at least, westward through Kelso to the Argus Mts. Cal- 

 ifornia, among junipers on dry slopes, in very poor soil, Lower 

 Temperate Life Zone.
