Var. PARViFOLius Wats. Bot. Cal. i, 102 (by misprint 

 parviflorus in the original). C. pirvifolius.* No. 23 

 from Calaveras Big Tree Grove. 



\C. integerrimiis] var. ? parviflorus. Of very slender habit, wholly glabrous ; 

 leaves much smaller, about half au inch long, short-petioled; flowers light 

 blue in rather short simple racemes. In the Sierra Nevada from the Yose- 

 mite Valley northward. Possibly distinct but intermediate forms occcur, 

 It is 51 Bridges, 1628 Brewer, 3880 and 4870 Bolander, 68 and 68« Torrey, 

 and was also collected by Bigelow and by Dr. Gray.— Watson in Proc. 

 Am. Acad, x, SS-t (1875). 



Var. Parryi (Trel.) No. 20 from Toll House, Mt. 

 St. Helena. 



C. Parryi, n. sp. Branches glabrate or sparingly villous, strongly 

 sulcate, more or less papillate: leaves narrowly elliptical-oblong, obtuse, 

 15X30 mm. or less, glandular serrulate, glabrous above, the lower surface 

 rusty-tomentose, at least along the veins: inflorescence oblong, inter- 

 rupted, terminating recurved-ascending slender, few leaved branches: flow- 

 ers blue. [Leaves narrow, 3-nerved, the nerves often concealed by the revo- 

 lute margins; fruit about 3 mm. in diameter.]— Known to me only from 

 specimens found in cultivation at Calistoga, Cal. (Parry, 1881, No. 33).—

Ceanothus integerrimiis v^ith the varieties enumerated 

 above is the onl}^ species properly belonging! to the Cal- 

 if ornian flora which shows entirely naked vv'inter branches. 

 The dead peduncular branchlets of the preceding year 

 are often conspicuous below the fresh flowering, and, 

 though not pecuHar to the species, are to a certain extent 

 distinctive. The range of variation is very great, as may 

 be seen in No. 26, all the branches included under that 

 having been collected within a few rods, and as no other 

 species of the section was found in the vicinity, there 

 could be no suspicion of hybridity. The leaf margin in

t C. sanguineus occurs in California only in the Siskiyou mountains 

 along the northern boundary.
