BOTANICAL NOTES. 267 



lectecl by the writer at Teliacliapi, and described under tlie 

 name of 31. geniculatus Greene, is bent at the joints in a 

 not always vain effort to produce roots — a peculiarity 

 which is often shared by the typical form. 



Castilleia foltolosa Hook. & Arn. — The relative propor- 

 tions of galea and tube, wJiich form the principal distinction 

 between this species and C. lanata Gray, as well as the 

 length and width of the leaves, are found to be variable. 

 The appressed woolin the latter species is usually branched, 

 though less so, and softer than in the first, and some of our 

 specimens of lanata are obviously woody at the base. The 

 species are brought still closer by the form collected on 

 Santa Cruz Island by Mr. E. L. Greene,, and later from 

 that place and Santa Rosa Island by T. S. Brandegee, and 

 described under the name of C. hololeuca Greene. In the 

 description, the calyx is said to be " deeply cleft on the 

 upper side, merely lobed on the lower;" but singularly 

 enough, the author's own specimens show them to be about 

 equally cleft before and behind. The leaves, also, are often 

 much wider than stated, and the bracts, according to Mr. 

 Brandegee, who brought fine specimens to prove it, are 

 usually red. The plant, though generally more shrubby 

 ihan foliolosa, is often like it only woody at base. 



Sphacele calycina Benth. — This is, evidently, another of 

 our variable species. Bentbam describes the leaves as 

 "irregularly dentate," and the corolla as "white?" — we 

 find it running from ochroleucous, through various dull 

 shades, to purplish, and the leaves either dentate crenate 

 or entire, with cuneate, sub-hastate or cordate base; the 

 floral sessile, the otliers wing-petioled. It is often low and 

 depauperate, but in sheltered places away from the imme- 

 diate coast — as on Mt. Diablo — it makes a strong shrubby 

 growth, three or four feet high. 



Var. GLABELLA. Gray, seems hardly worth the rank, run- 

 ning directly into the ordinary form.
