region. Kellogg's type was from "Mariposa." The fact that 

 the plant was described as a Calliprora at once dismisses the 

 guess that it might be a "stout form of Brodiaea gracilis." Dr. 

 Kellogg was undoubtedly familiar with the considerable differ- 

 ences in floral structure of the genera Calliprora and Triiclcia, 

 and would hardly make such an evident error. I have collected 

 the plant in Kern county, California, and it is certainly distinct 

 from C. ixioides. The original spelling of the specific name is 

 here used. Wherever cited in literature it is spelled aurantca.

 Wherever mentioned, this is said to be the same as Arabis 

 Holboelii Hornem. But the latter species is now pretty gener- 

 ally conceded to be absent from the flora of the United States, 

 the original being from Greenland. I have not been able to 

 determine to what species of Arabis it really belongs, but it 

 hardly seems possible that the plant has escaped a later descrip- 

 tion and name unless it is an extremely local species. The type 

 was collected near Washoe, Nevada, a point between Reno and 

 Carson, but in a region little explored botanically. The plant 

 is "light greenish gray, with short white forked or branching 

 hairs throughout, " and the calyx is described as 'erect at length 

 recurved spreading; purplish green, (slightly purplish at the 

 base) sepals somewhat spatulate, subacute, half shorter than the 

 petals, equal at the base or not saccate." The petals are de- 

 scribed as "beautiful deep rose purple on the lamina, the claws 

 white, cuneiform-spatnlate, nngnicnlate, claw scarcely a little 

 longer than the sepals, five to seven-nerved." The pod is about 

 two inches long, "straight or a little curved, strongly reflexed 

 against the stem, pedicels scarcely three-eighths of an inch long." 

 Whatever the plant may be, the name is preoccupied by the 

 earlier Sisymbrium rejlexum of Nnttall.
