pauiculatus by the absence of sheaths and by the only simple 

 racemes, as well as by the habitat which is a wet meadow, 

 while the other species does not grow in wet meadows. This 

 is a fair sample of Rydberg's accuracy in dealing with Zyga- 

 dcnus. There is absolutely no character to separate veneno- 

 sns from paniculatus but the absence of sheaths to the stem 

 leaves and the habitat. The perianth varies from l5'2-4 lines 

 long, from hyaline to green, from long-clawed to short-clawed. 



Zygadenus Fremonti var. brevibracteatus n. var. 



This differs from the type in having very narrow leaves, 

 email flov/ers about 3 lines long, ample and compound racemes, 

 lJ/2 feet long, stout and horizontal pedicels 12-18 lines long, 

 ovate-lanceolate bracts about 6 lines long; plants 2 feet high, 

 growing among rocks. This is not the variety minor, but is a 

 fiesert form of this well known coastal species. Growing 

 among rocks at Victor, California, on the Mojave Desert, May 

 18. 1903, at 2900 feet elevation. 



Calochortus Nuttailii var. subalpinus n. var. 



E'ase of anthers sagittate, body linear but narrower above, 

 2 lines long; pods lanceolate and deeply sulcate, 1 inch long; 

 steiuss 2-3-leaved; petals rhomboidal, very obtuse, light-purple, 

 or purple-veined to nearly white, with a variable purple spot 

 near the base. There are two forms, one of which is low with 

 ilexnous and short-stemmed and umbellate flov/ers, the other 

 vvhh tall and simple anl 1-flowered stems which are barely 

 llexuous and erect. This growls on the high ridges at Sum-
