would be more fitting to raise this variety to specific rank 

 C. montanus. Mr. Parish says that invenustus is well con- 

 nected by intermediates with var. montanus. In the mountains 

 at Bear Valley these two are very distinct. 



C. invenustus is abundant on the dry slopes among the 

 live oaks and brush at Seven Oaks, at 5000 ft. alt. and 

 was not seen at over 5500 ft. alt. 



C. montanus is common on the dry slopes around Bear 

 Valley dam at 6700 to 7000 ft. alt. The range of the two 

 plants is here quite distinct with 2000 ft. alt. between and 

 an examination of hundreds of them showed no intermediate 

 forms. 



On San Jacinto or other mountains it may show inter- 

 mediates, as Parish says. 



C. montanus lacks the green stripe on the exterior of 

 the petals. These are darker sometimes deep purple colored 

 with the claw yellow. If it possessed a light colored petal 

 with a lighter colored claw than invenustus it might be 

 considered a mere variation, but the darker petal witli the 

 lighter gland seems to negative this conclusion. 



For the easier determination of herbaria specimens of 

 the lilac colored non-oculate species, the following key may 

 prove useful : 

 Flowers umbellate 

 Stems bulbiferous 



Claw dark C. invenustus. 



Claw yellow C. montanus. 



Stems not bulbiferous C. striatus. 



Flowers not umbellate 



Stems not bulbiferous and sepals not recurved. C. Dunni. 

 Stems bulbiferous and sepals recurved. 

 Flower cup shallow, gland triangular. 

 Flower cup deep. 

 Petals erose, gland small. 

 Petals not erose, gland indefinite. 



C. paludicola. 



C. splendens. 

 C. Palmeri.
