Lycium, sp., near L. Calif ornicum. 



Lycium, sp., near L. gracili'pes. 



Many of our species of Lycium seem too closely related; 

 a careful study of intermediate forms in the field would 

 probably much reduce their number. 



Antirrhinum cyathiferum Benth. 



Dr. Gray, in his Synoptical Flora, casts a doubt upon 

 the distinctness of his A. chytrospermum, in the following 

 words : 



''A. cyathiferum of Lower California appears to differ from 

 the following in having linear-lanceolate sepals of only half 

 the length of the tube of the corolla and a shallower cup to 

 the seeds." The specimens brought by Mr. Bryant from Mag- 

 dalena Bay show great variation in the comparative length of 

 the sepals and tube of the corolla, as well as in the cups of 

 the seeds, so that it is probable a careful comparison will 

 show them to be too closely related. 



No one familiar with 31ohavea viscida Gray {Antirrhinum 

 coyifertiflorum Benth.) can look at these plants and fail to be 

 struck by their close relationship, especially in habit, cap- 

 sules and seeds.
