forms found in herbaria under the name of Pentstemoit corym- 

 bosus Benth., a species which perhaps has never been re-col- 

 lected, although many specimens are labeled as such. It was 

 originally collected somewhere in California by Coulter, and 

 described by Bentham as having a glabrous sterile filament. lu 

 this particular, as well as in several others, it does not agree with 

 our plant or the P. corymbosus of the Synoptical Flora. The 

 following is the original description: 



"P. CORYMBOSUS (Benth. in lit.); glaber vel pubescens, 

 caule humilis decumbente, foliis caulinis brevissime petiolatis 

 oblongis obtusis subdentatis, cyma terminalia nuda trichotoma 

 multiflora corymbiformi, corollae tubo tenui calyce triplo longi- 

 ore, limbo profunde bilabiate, fllamento sterile glabro. In Cal- 

 ifornia (Coulter!). Specimina vix 4-pollicaria. Foliorum forma 

 et ramulorum pars inferiora Veronicam officinalem referunt. 

 Folia caulina vix semipollicaria, floralia ad bracteas minutas re- 

 ducta. Calycis segmenta lanceolata, 3 lin. longa. Corollae 

 tubus 9 lin. labia 3 lin. longa. Antherae glabra, (v. in herb. 

 Hook.)"— DC. Prodr. 10: 593. 1846.

 Although Mr. Howell has kept both C. ca7nporum and C. 

 lutea as distinct species in his Flora, they are undoubtedly one 

 and the same, for I have been able to satisfy myself upon this 

 point through the kindness of Dr. B. L. Robinson, of the Gray 

 Herbarium, who submitted to me for examination the type of C. 

 camporum.
