380 CALIFORNIA.— SUPPLEMENT. IScrophularinece. 



1. Castilleja purpurea. Nutt. in Trans. Am. Phil. Soc. 5. p. 180. 



Our specimen, for we have seen but one from Mr Douglas, has smaller and brighter red flowers than in 

 that we have obtained from Nuttall himself, but in almost all other respects they seem to agree. 



2. C. hispida. Benlh. in Hook. Fl. Bor. Am. 2. p. 105? 



Hab. Bruneau, Snake Country. Mr Tolmie. 



The height of our plant is, according to Mr Tolmie, one to three feet. The leaves are divided as in C. 

 coccinea, but the calycine segments are ovate-oblong, almost like those of C. septentrionalis. It is hispid, 

 as the original C. hispida, but the calycine lobes are shorter, not oblong-linear, as in C. pallida. The 

 flowers and bracteas appear to have been red. 



3. C. septentrionalis. Kunth. — 'Benth. in Hook. Fl. Bor. Am. 2. p. 105. 



This Californian plant may perhaps be very different. The lobes of the calyx are broader and shorter than 

 in North American specimens ; the bracteas and calyx, although pale, have a tinge of red, and may have 

 been deep red when fresh ; the leaves on the young branches are linear and obtuse ; those on the stem, at 

 the origin of the branches, trifid to about the middle, their segments linear and obtuse ; bracteas (at least 

 the lower ones) cuneate and trifid ; flowers subsessile. The habit is somewhat that of C. lithospermoides. 



4. C. affinis. Hook, et Am. supra, p. 154. 



5. C. latifolia. Hook, et Am. supra, p. 154. — C. macrocarpa. Benth. Scroph. Ind. p. 13. 



The upper lip of the corolla is shortly exserted beyond the calyx. 



6. C. foliolosa. Hook, et Am. supra, p. 154. 



Our original form of this plant has the leaves approximated, the axils bearing tufts of similar leaves, so 

 that the whole merited well the name we gave. But in Douglas' collection are specimens of two other 

 varieties or forms, which assume a considerably different appearance. The first of these has the leaves twice 

 the length of Beechey's specimens, and their secondary leaves in the axils are very small and few. The 

 second has the primary leaves still larger, less tomentose, and sometimes trifid to beyond the middle ; the 

 secondary leaves are copious, as in Beechey's plant ; the spike is partly in fruit, and much more elongated 

 and lax than in the other specimens. In Beechey's and the last mentioned form, the stems seem decidedly 

 woody, in the other one somewhat herbaceous ; so that we have no doubt but the above different appear- 

 ances arise from the plants having been in different stages of growth, and from the specimens having been 

 taken, in the one case, from the old branches, in the other from the young shoots.
