II. AN ABNORMAL PHACELIA.

hills and lower mountains of southern California. It is an annual, 

 with ovate or cordate leaves coarsly serrate, and the flower has an 

 ample blue corolla of typically campanulate form, somewhat spread- 

 ing at the mouth, and with a narrow 5-parted limb. » 



To it I must refer a plant quite different in many respects, and of 

 sufficient interest to deserve brief record. The basal leaves of the 

 specimen are wanting, but all the cauline are narrowly oblong and 

 entire. The corollas are somewhat reduced, and are divided to the 

 base into six very narrow lobes, the tips dilated. So deep is the 

 division that the flower appears polypetalous. The calyx-lobes are 

 normally linear but are six in number and the stamens are also 



On the other hand the gynoecium is regular, the pistil being 

 2-cleft and the ovary 2-celled and many-ovuled. 



A consideration of the position of this plant illustrates the arti- 

 ficiality of systematic distinctions, and even of some morphological 

 definitions. Supposing it to be an abnormal Phacelia, the pubcs- 

 ence and the characters of the ovary bring it into the section Whit- 

 lavaa. Here are two species with which it agrees in habit of growth 

 and in the possession of a campanulate corolla, but from which 

 itdifiers entirely in the very important characters of the shape and
