CALIFORNIA.— SUPPLEMENT. 



[Saxifragece. 



Some of the young vigorous unbranched shoots, which are from a foot and a half to two feet long, are 

 clothed with numerous rigid bristles or prickles, which give those portions of the plant a very different ap- 

 pearance from that in which it is usually figured and described. We have seen no fruit. 



6. R. Californicum ; glabrum, ramis nudis, spinis stipularibus ternis, foliis cordato- 

 reniformibus 3-5-lobis, lobis subincisis, pedunculis 1-3-floris, bracteis rotundato-ovatis, 

 calycis tubo brevi, laciniis ovato-lanceolatis tubo 3-plo Iongioribus demum reflexis apice 

 glabris, staminibus petala triplo superantibus styloque simplici glabris, ovario glandu- 

 loso-piloso. 



This differs from R. niveum, Lindl. (with which we are only acquainted from the figure in the Bot. 

 Register), besides what is pointed out in the above diagnosis, by the erect, or rather patulous, not connivent, 

 stamens. 



7. R. occidentale ; glabrum, ramis nudis, spinis stipularibus solitariis, foliis cordato- 

 reniformibus 3-5-lobis, lobis incisis, pedunculis 1-3-floris, calycis laciniis oblongis tubo 

 sublongioribus demum reflexis apice pedicellatis staminibus petala triplo Iongioribus 

 glabris, stylo glabro ultra medium bifido stamina superante, ovario echinato. 



The stamens in this and the next species, as well as in the last, have their anthers ovate, much larger in 

 proportion to the flower than is usual in the genus, and tipped with a distinct blue mucro. 



8. R. subvestitum ; glanduloso-pubescens (foliis supra exceptis), ramis rigide setosis, 

 spinis stipularibus 3-4 gracilibus, foliis cordatis 3-5-lobis supra parce pilosis, lobis incisis, 

 pedunculis 1-3-floris, calycis pubescenti-glandulosi tubo ovarium subduplo superante 

 laciniis oblongis parium breviore, staminibus petala duplo superantibus glabris, stylo 

 glabro simplici (nunc bifido !), ovario piloso-glanduloso. 



In all the flowers, except one, the style is decidedly simple, but in that one it is bifid to near the middle. 

 The whole plant, with the exception of the upper side of the leaves, is covered with a glandular pube- 

 scence: the ovarium, although glandular and hairy, exhibits no tendency to become a prickly fruit. 



9. R. trijlorum. Willd. 



Ord. XXV. SAXIFRAGES. Juss. 



1. Tellima (Lithopbragma) parvifolia ; hirsuta scabra, foliis omnibus tripartitis, seg- 

 mentis inciso-pinnatifidis, petalorum lamina tripartita ovario semi-infero. Hook. Fl. Bor. 

 Am. v. 1. p. 239. t. 78. A. 



Hab. Green River of the Snake Country. Mr Tolmie. 



2. T. (Lithopbragma) heterophylla ; birsuto-scabra, foliis radicalibus cordatis 3-5- 

 lobis crenato-lobatis, caulinis profunde 5-fidis, lobis inciso-trifidis, petalorum lamina 

 apice trifida, ovario omnino supero. 



The sub-genus Lithophragma of Nuttall (PI. Rock. Mount, p. 26), we are disposed to distinguish by 

 the unguiculate 3-lobed petals, and three distinct styles, while in the true species of Tellima, the petals are 

 oblong-linear, sessile and irregularly laciniate, and the styles only two. From this sub-genus we of course 

 exclude Mile/la tri/ida, to include which Nuttall has given a very different character. The present species 

 varies extremely in the size of the foliage, the leaves being sometimes only one inch, in other specimens two 

 or even three inches in diameter.
