STUDIES IN CEANOTHUS. 203 



Var. PAPiLLOSUS (Torr. & Gray). 



Cecmothus papiUosus: branches tomentose; leaves narrowly oblong, much 

 crowded, fascicled iu the axils, densely and softly tomentose beneath, 

 glandiilarly dentici;late on the margin [1-ribbed, piunately veined]; pe- 

 dnncles aggregated, clusters somewhat capitate; ovary triangular, the 

 angles projecting at the summit. California, Douglas! — Branches terete. 

 Leaves 1-1 1 inch long (those fascicled in the axils smaller), fringed on the 

 margin with numerous capitate glandular teeth; the upper surface con- 

 spicuously papillose and somewhat hairy. Peduncles numerous at the 

 summit of the branches; the flower-buds at first invested with ovate 

 woolly bracts: pedicels 2-3 lines long. Flowers blue. — Torr. & Gray, Fl. 

 N. Am. i, 268 (1838). 



In Dr. Parry's revision of Ceanothus C. deutatns was 

 reduced to C . papillosus. He had not then seen C . den- 

 tatas growing, and after so seeing it, altered his opinion. 

 He was, however, without knowledge of the forms since 

 collected, and contrasted the typical forms of each. The 

 epidermis of C . ■papillostis is occasionally white and de- 

 ciduous as is shown in No. 56, and even in some spec- 

 imens of Parry's distribution, a character which strength- 

 ens its relationship to C . Lem^noni. Miss Eastwood has 

 collected specimens in the Santa Lucia Mountains with 

 lilac flowers, and extremely narrow leaves, which are 

 closely revolute. The range of the variety is shown 

 by the localities given for the specimens. On the bare 

 grassy mesas sloping upward from the sea at San Sim- 

 eon, it grows prostrate on the ground, often entirely 

 hidden by the grass and stunted weeds. This form. 

 No. 53, is frequently quite destitute of papillge. No. 53, 

 San Simeon; No. 54, Ben Lomond, Santa Cruz Mount- 

 ains; No. 55, Big Tree Grove, near Santa Cruz; No. 



56, Forest Grove, near Wright's, on the eastern slope of 

 the Santa Cruz Mountains. The known hybrids (Nos. 



57, 58, 59, 60) have been already noticed under C . iiite- 

 gerrimiis, C . tiicanus, C . thyrsijioi'us and C . hirsiitus.
