226 ILLUSTRATIONS OF THE BOTANY OF [Sazifragee. 
Deyra Doon a very distinct species is found, J. nutans, nob. (Ic. ined. 146), resem- 
bling J. virginica in habit, and in having terminal spike-like racemes, of which the 
capsule separates on ripening into two distinct carpels. In J. macrophylla the spikes 
are axillary, and 2 to 3-fascicled. (v. Wall. Jc. ined. 156.) The other species of the 
genus are found in China and North America. 
The true Sazifrages are well known from being so common in the mountains and 
fields of European countries. They are found in other cold parts of the world, as both 
Northern Asia and America, the mountains of South America, and the Straits of Magal- 
haens, as well as on the Himalayan mountains. The genera found in the latter are 
Savifraga, Chrysosplenium, and Parnassia, common in both Europe and North America, 
Tiarella, found in the latter only, with Astilbe, peculiar to these mountains ; A. rivularis, 
Don (Spirea triternata, Wall. 706) occurs in Nepal, and also at Mussooree. 
Of the Sazifrages, S. ciliata and ligulata are allied to S. crassifolia ; S. odontophylia, 
and S.lanuginosa, nob, to S. granulata and Sibirica. S. stenophylla, t. 50, from Peer- 
punjal, is so like specimens of S. flagellaris, from Melville Island, as only to be distin- 
guished on a close inspection. S. mucronulata (spinulosa, t. 50. f. 2), with S. aciculata, 
nob., allied to S. Brunonis, and S. brachypoda (glandulosa, Wall.), belonging to the 
same group, are found on Choor and Kedarkanta, where the climate, from the short- 
ness of the season after the melting of the snow and the power of the sun, has been 
compared to that of polar regions, p. 20. S. imbricata, t. 49. f. 1, is one of the singular - 
forms found in Kunawur. 
S. parnassifolia, Don, which varies so much, as apparently to include both S. diversi- 
folia and Moorcroftiana, resembles, in one of its varieties, Parnassia, very closely in 
foliage. This genus, referred here by Mr. Brown and Dr. Lindley, has a_ species, 
P.nubicola, common every where in these mountains, the rest of the genus being 
found in Europe, Eastern Siberia, and North America. Vahlia, referred here by De 
Candolle, but still continued in Onagrarie by Bartling, is the only genus which displays 
the anomaly of growing only in hot parts of the world, as Egypt, Senegambia, and the 
Cape ; and in India, in Tranquebar. 
Saxifraga imbricata ; caulibus numerosis dense ceespitosis foliosis, foliis minimis undique arctissime 
imbricatis ovatis oblongis crassis apice subtriquetris puncto terminali marginibus ciliato-serratis, floribus 
solitariis terminalibus, sepalis glanduloso-ciliatis, petalis obovatis unguiculatis trinerviis sepalis longio-

Saxifraga ramulosa ; Wall. Cat. N. 446. Ser. in DC. Prod. 4. p- 21.—Tab. 49. f. 3. 
Though it agrees in so many respects, I have hesitated in referring this plant to S. ramulosa, 
described by M. Seringe from imperfect specimens; in consequence of its more diffuse habit, the branches 
being frequently terminated by solitary flowers, and the leaves being smaller and more obtuse; but 
these differences are not greater than those observed in the varieties of S. c@sia, to which this species is 
most closely allied. 
S. ciliata, Tab. 49. fig. 2. . 
T have had some difficulty in naming this plant, as the published descriptions, as well as the distri- 
buted specimens of Wall. Cat. 4492. and figures of S. ligulata, to which it is most nearly allied, do not 
correspond with one another ; indeed, two distinct species pass under that name. Dr.Wallich (As.
