(lin. 4-5 longa) subdimidio brevioribus ; filamentis basi crebre barbatis 

 corolbe lobis rotundatis paullo brevioribus. 



Lycium macrodon, Gray, the remaining species of the calycose and 

 pentamerous group, has been rediscovered by Mr. Priugle, at a more 

 southern station, namely, within the borders of Sonora. It has re- 

 markably long calyx-lobes, the white corolla tinged with green, and 

 under the ovary an extremely large and deep orange-colored disk. 



Lycium Palmeri, Gray, would seem to be the L. quadrifdum of 

 Dunal.

 — Guadalupe I\rountains, Western Texas, not far from the Rio 

 Grande, 1882, Dr. V. Ilavard. Apparently the same species (noted 

 as having purple flowers) is no 245 of coll. WisUzenus, which is said 

 to have been collected in Mr. Pott's garden at Chihuahua; but the 

 specimen is too incomplete for certain determination. The ticket 

 states that the species is spontaneous near Chihuahua.
