analytical points of difference, it may be said that in cultiva- 

 tion this form proves to be a stronger and hardier plant than 

 the type, A curious fact in connection with the bulb is also 

 worthy of mention. The coarse fibrous coating which the 

 variety has in common with the type is often found to cover 

 not one bulb, as is usual, but two large bulbs of about equal 

 size, laid so flatly face to face that outwardly the bulb 

 retains the round form of the species, and it is only by 

 breaking the coating that the presence of the second bulb 

 is discovered. This habit of the bulb can hardly be called 

 offsetting, as it is impossible to call either the parent bulb. 

 In the San Jacinto Mountains this form varies to pale pink 

 and white. It is the C. weedii var. alhus of horticulture. 

 A fine plate of this variety may be found in "The Gar- 

 den," Feb. 2, 1895. 



23^. C. zueedi var. vestus. Continuing still further 

 north to Santa Barbara, we again find the species, but the 

 petals are much more truncated and curiously fringed with 

 brown hairs, while the color is reddish brown. 



23c. C. weedii var. obispo'ensis, var. nov. (C obispo- 

 ensis Lemmon, Bot. Gaz., Vol. XI, 1886, p. 180.) This is 

 an extreme form found in San Luis Obispo County. The 

 petals of the flowers are still more truncated than in the 

 preceding, and near the town of San Luis Obispo, which I 

 think is the northern extreme of its range, the flowers 

 assume a most fantastic form, the brownish petals being so 

 much truncated that the sepals far exceed them, and the hairs 

 which are scattered in typical specimens here seem to be 

 condensed upon the small remaining surface of the petals. 

 "On dry, stony hills near San Luis Obispo, Cal." 

 It is, of course, impossible to enumerate here all the 

 many gradations in this plant, which forms one of the most 

 interesting studies in plant variation. 



Group 4. Golden Bowl Mariposas. 



Petals yellow, lower half covered with clavate hairs; radical leaves long;- 

 linear and deeply channeled.
