the Sierra Nevada, to which the typical form seems to be 

 confined. 



Var. FOLiosus (Parry). C . foliosiis, C. Lemmoni* 



C . foUosus, n. sp. Branches slender, divergent, pubescent when young; 

 leaves somewhat coriaceous, crowded, fasciculate, small — 5 to 8 mm. long — 

 ovate, obtuse, narrowed at base to a short ijetiole, irregularly crenate, with 

 frequent resinous glands, obscurely triple-nerved near the base, not revo- 

 lute at the margin but inclined to fold back on the midrib; inflorescence 

 terminal and axillary, loosely globose, or slightly elongated; flowers few, 

 on short pedicels, light blue; fruit triangular, 3-4 mm. broad, sharply 

 crested at thesiimmit. Habitat: — A densely branched shrub, 3-5 feet high 

 with light green leaves, more or less resinous glandular; has been referred 

 to C. dentatuH — included above as a variety of C. papiUosus — from which it 

 diff'ers in every essential chai'acter. In its general features it comes nearest 

 to the South Atlantic coast species, forming with them a well-marked 

 group, approximating the section [Cerastes] following. The specimens 

 seen were collected in the upper Napa Valley, where it is abundant, being 

 associated with C. Parryi and C. divergens. — Parry in Proc. Davenp.

Typical C. foliosus or the still more pronounced form 

 found on Tamalpais seems to be far enough removed 

 from either C. decuDibens or C. Lemmoni , but they are 

 all closely connected by forms common in Lake and 

 Mendocino counties. C . foliosus has been usually con- 

 sidered a form of C . dcntatus, to which it is indeed 

 rather nearly related. No. 46, Cahto, Mendocino Coun-

*Geanothns Lemmoni, n. sp.: Two feet high or less, spreading with rigid 

 branches, bark lightish gray, more or less hairy pubescent on the younger 

 stems; leaves narrowly elliptic to oval, 10 to 25 mm. m length, smooth 

 above, ciliate pubescent on the veins beneath, glandular-serrate, the ser- 

 rations most distinct on young, vigorous shoots, stipules somewhat rigid; 

 inflorescence short on jjrolonged leafy i^eduncles, flowers of a light or faded 

 blue color; fruit 4 mm. broad, conspicuously crested. Habitat: — John- 

 son's Ranch, near Quiucy, Plumas County, Lemmon, 1874, — May 30, 1889.
