Maweanus. Its nearest relative is, however, C. Tolmiei, 

 which belongs to the same region and from which it can 

 readily be distinguished by the absence of the scale cover- 

 ing the gland of the latter. Most of the C. Tolmici in 

 herbaria is probably this species. It was compared with 

 the original specimen of C . Tohniei at Kew b}^ J. G. Baker 

 who says: "The Willamette plant differs a good deal from 

 the original C. Tohniei. C . Tohniei has pale lilac petals 

 bearded all over the face, no spot, no scale, no obtuse 

 anthers." There is no true C. Tohniei m the Herbarium 

 of the Academy. We have specimens collected by Thos. 

 Howell, from Grant's Pass, Oregon, from Prairies, West- 

 ern Oregon, April 1881, and from Hillsboro, Oregon, 

 May 1881, all marked C. Tohniei, but each with a scale 

 covering the gland and with flowers creamy rather than 

 blue. It would seem as if the anthers were variable, since 

 all of C . Purdyi that I have examined have acuminate 

 anthers ; but evidently the specimens sent to Kew had 

 obtuse anthers. 



C. Purdyi grows in the Willamette Valley, in the foot- 

 hills on dry gravelly soil. It is never found in shaded 

 woods. 



It is named in honor of Carl Purdy who knows Calo- 

 cho7-ti more intimately than anyone, and whose work on 

 the genus in the garden, the field, and the study has accom- 

 plished so much towards determining the true specific limits 

 in this difficult and variable genus. ^ 



1 Since the above description was written and the drawings made, a beautiful figure 

 of this species has appeared in " The Gardeners' Chronicle," Vol. I, 1898, p. 305, fig. 147. 

 The flower is much larger than that of any specimen seen by me. It is not unusual, 

 however, that plants have larger flowers under the more favorable surroundings that 

 cultivation produces. It is a well known fact that I'acific coast species vary consider- 

 ably in the size and vigor of individuals according to the amount of moisture and 

 fertility of the soil.
