Jepson Field Book volume 26 page 10
Berkeley  - Rosa. R. pisocarpa has no essential pt. of dif. with R. cal. and I doubt its distinctness. I have made out a pt. as to stip. for use in Shrubs Cal. but I doubt if it holds. R. pisocarpa seems to have suddenly enlarged stip. tips often somewhat flabellately dilated. [See image for drawing.] R. cal. seems remarkably variable in pubescence or lack of it and thinness or thickness of fol. R. pisocarpa, calyx-lobes not reflexed on hips as said in Bot. Cal.; leaflets more likely to be petiolules [?] than in R. cal. -- Sept, '12  Look up Crepin, Bull. Soc. Bot. Belg. 15 (1876) Monog. [?] Roses; he has a no. of vars. of R. calif. Ellen Willmot, the Genus Rosa, an elaborate but not very satisfactory treatise as to specific ::::::::: Sept. 1912 distinctions. She says R. californica has deciduous sepals.  I find no essential distinction betw. R. cal. & R. pisocarpa. Yet the typical R. cal. with its stout-based prickles is very dif. from R. pisocarpa. The S. Cal. forms of R. cal. are hard to separate. -- Oct. '12. - One is very much amused at the men who never admit not knowing a thing. Leonard Bacon, a bright young chap, replied to a query in a circle at the Faculty Club that he had never read Dickens' Our Mutual Friend. One of the older professors took him aside afterwards and told him not to admit such things!!! Perhaps one has to know a big lot to say he doesn't know!! - Ethereal oils and native shrubs. Prof. Hilgard remarked today that he had Calycanthus, presumably C. floridus, in his garden and that it was quite lacking in odor as compared with the same shrub in its native home. Shrubs too, along the coast, lack the odors of shrubs in the interior or Great Valley, esp. chaparral shrubs. -- Oct.1.
