340 CALIFORNIA.— SUPPLEMENT. lOnagrariea. 



1. Photinia arbutifolia. Lindl. — Hook, et Am. supra, p. 139. 



We do not see that P. nudiflora of Nuttall's ms. in Herb. Hook, differs in any respect from the present 

 species. This was first discovered by Mr Meuzies, during Vancouver's voyage. • 



1. Cerasus ilicifolius (Nutt. ms.) ; foliis coriaceis perennantibus lucidis cordato-ovatis 

 breve petiolatis spinoso-dentatis, racemis densifloris axillaribus terminalibusque folia 

 asquantibus, bracteis pedicello brevioribus. (Tab. LXXXIII.) 



This singular species has leaves resembling those of the Holly, equally harsh, rigid, and spinous ; but with 

 the fruit we are unacquainted. The racemes are copious and thickly flowered.

Ord. XIX. CALYCANTHE^. Lindl. 

 1. Calycanthus occidentalis ; foliis ovato-lanceolatis acuminatis rigidis nitidis utrinque 

 concoloribus scabridis glabris, pedunculis elongatis. (Tab. LXXXIV.) 



Branches smooth, of a rusty red colour. Leaves subcordate at the base, about six inches long and two 

 broad, gradually acuminated from below the middle, where they are broadest, to the apex, neither glaucous 

 nor tomentose underneath, even when young. The peduncles are either terminal, or from the forks of the 

 branches, and from two to three inches long when the flower is expanded. 



Tab. LXXXIV. Calycanthus occidentalis. — Fig. 1. Calyx-tube, showing the stamens, the sepals being 

 removed ; fig. 2. Stamen ; fig. 3. Calyx-tube laid open, showing the ovaries. 



Ord. XX. ONAGRARIEiE. Juss. 



1. Zauschneria Californica. Presl, Rel. Hcenk. p. 28. t. 52. Hook, et Am. supra, p. 140. 



Of this there are two forms in the collection : the one has the whole plant, but especially the leaves and 

 flowers, much more densely canescent than the other ; its flowers too are smaller, and of a less lively red 

 colour. 



1. Clarkia pulchella. Pursh. — var. flore purpureo et albo. 

 Hab. Snake Country, about Snake Fort. Mr Tolmie. 



2. C. elegans. Lindl. — Phseostoma Douglasii. Spach, Suites a Buffon, IV. p. 393. 



This varies much in the hairiness of the ovarium and calyx ; but is quite distinct from the following, with 

 which Spach unites it. 



3. C. rhomboidea. Dougl. in Hook. Fl. Bor. Am. I. p. 214. Lindl. Bot. Reg. t. 1981. 

 — C. gaurioides. Hortul.—Don in Sweet Br. Fl. Gard. 2d. Ser. t. 379. 



1.' Eucharidium concinnum. Fisch. et Meyer — Hook. Bot. Mag. t. 3589. 



A solitary specimen of this we found mixed with Clarkia rhomboidea, with the foliage of which it agrees 

 pretty well ; but it has very different flowers. 



1. CEnothera (Holostigma) alyssoides ; humilis multicaulis puberula, foliis inferioribus 

 multo majoribus oblongo-lanceolatis inaequaliter dentatis in petiolum attenuatis caulibus 

 paullo brevioribus, superioribus linearibus, racemis foliosis secundis circinnatis, ovariis
