PenLtstemork ParisKii, a. hybrid 



BY A. DAVIDSON, M. D. 



In May of this season in an excursion to the foothilir^ 

 Messers Braunton, Greata and Johnston at Glendora, and Dr. 

 Kraemer and the writer at Azusa, gathered some specimens of 

 Pentstemon that were new to the county and somewhat un- 

 familiar. Mr. Parish to whom the specimens were referred 

 named them P. Parishii 



The plants were compared and discussed at a subsequent 

 meeting, and the evidence seemed conclusive in favor of this 

 plant being a hybrid between P. centrantJiifolins, Benth, anc 

 P. spectabilis, Thurb. 



In color P. Parishii varies from a livid purple to a bright 

 red. The leaves are entire, or occasionally denticulate and clasp- 

 ing at the base. In centranthifolms they are entire and scarcely 

 clasping, while in spectabilis they are spinulose denticulate and 

 connate. The inflorescence is intermediate in shape between 

 the virgate raceme of the one and the expanded thyrsus of the 

 other. The flowers are less ventricose than those of spectabilis 

 and more dilated than those of centranthifolkis. The description 

 given in Gray's Snop. Fl. though accurate might with advantage 

 be more detailed. The sterile fllaments in our specimens were 

 not hooked. 



Since the above was written Mr. Hall's work on the Flora 

 of San Jacinto has appeared and I find that he likewise considers 

 P. Parishii a hybrid. This is a new addition to our published 

 county list. Wallace I believe found it in the neighborhood of 

 lyOS Angeles long ago but whether the locality was within the 

 present county boundaries I have no means of ascertaining.

The botanical publications of the University of California have begun 

 most auspiciously with Mr. Hall's careful study of the pine belt of San 

 Jacinto Mountain. The southernmost lofty summit of the Sierra Nevada 

 rises from a desert base of but 500 feet above sea level with precipitous 

 abruptness to an Alpine height of nearly ii,oco feet; to the south and west 

 dominating the rugged convolutions that separate it from the sea. San 

 Jacinto occupies a position which gives its flora a peculiar interest. To a 

 statement of the conditions thus presented, and to the working out in 

 detail of the resultant problems, Mr. Hall has devoted his first fifty-two
