CALIFORNIA.—SUPPLEMENT. 
ISaxifragece. 
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 nudisj spinis stipularibiis ternis, foliis cordato- 
reniformibus 3-5-lobis, lobis subincisis, pedunculis 1-3-floris, bracteis rotundato-ovatis, 
calycis tubo brevij laciniis ovato-lanceolatis tubo 3-plo longioribus 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. 
Registei'), 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 S-S-lobis, lobis incisis, pedunculis l~3-floris, calycis laciniis oblongis tubo 
sublongioribus demum reflexis apice pedicellatis staminibus petala triplo longioribus 
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. siibvestitum ; 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 tendencj’’ to become a prickly fruit. 
9. R. triflorum. Willd.

1. Tellima (Lithophragma) parvifolia ; hirsuta scabra, foliis omnibus tripartitis, seg- 
mentis inciso-pinnatifidis, petalorum lamina tripartita ovario semi-infero. Hook. FI. Bor.

Hab. Green River of the Snake Country. Mr Tolmie. 
2. T. (Lithophragma) heterophylla ; hirsuto-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 (PL 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 Mitella trifida, 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.
