parents in one important point, that of color. In tlie garden 

 bed where these plants grew with me, some growing leaves 

 were remarked by me as being of a decided blue-green shade, 

 which was a thing new to me in this genus, except in B. ccqn- 

 tata; and, although the leaves were dead before the plants 

 were in full flower, I believe it was the plants of glaucescent 

 foliage which produced the flowers of B. venusia. I make 

 this suggestion, and hope that Mr. Purdy may be able either 

 to confirm or disprove the truth of it another season. If the 

 plant in question be a hybrid it does most conclusively invali- 

 date Brevooriia, a genus in which I have no longer any faith 

 any way; though I am as firm as ever in the belief that Bro- 

 diwa and Hool^era are distinct.

II. 



In this article— a continuation of the subject from page 

 139 of the first volume— I propose the restoration of Mr. Ben- 

 tham's genus LiNANTHUS, to include several other allied 

 groups of plants which, in the conventional floras and man- 

 uals of the time, are ranged under Gilia. 



I have long been persuaded that one or the other of two 

 methods of disposing of them, outside of Gilia, will have to 

 be accepted. They must be received as forming a natural 

 genus, intermediate between Gilia and Phloir, or they must 

 be merged in the latter genus, for which they have decidedly 

 a stronger affinity than for Gilia. 



The only constant character by which they differ from 

 Phlox is that of the equal insertion of their stamens. The 

 corolla in very many species is just that of Phlox, while in 

 others it is much more open, coming out, in some, to the open- 

 carapanulate or almost rotate. But, as I have remarked in
