94 BOTANICAL INFORMATION. 
senilis (anbranched) e other Cactee, Larrea Mexicana, &e., but the 
individual kinds are not clearly indicated in the text. Larrea Mewicana is 
the ** Creosote Plant," esr by Moricand, PL. Nov. p. 48, or Lodeondo 
of the New Mexicans, used externally for rheumatism. It has a powerful 
smell: no animal feeds upon it, and it is even useless as fuel, as it can 
scarcely be made to burn. 
Several new species of plants are described by Dr. Torrey. Among 
the more remarkable we may mention the little-known Fallugia paradoxa 
of Endlicher (Sieversia paradoxa, Don, in Linn. Trans, vol. xiv. p. 376. 
t. 22). We possess what we consider the same plant in Fendler's 
Plantze Novo-Mexieanz, n. 193 ; but there the flowers are about as 
large as those of our Dog-rose. In Don’s figure they are rather 
more than half that size; while in Dr. Torrey's plate they are not so 
large as those of Potentilla reptans. Dr. Torrey queries if it be not 
the Geum dryadoides of De Candolle: it sufficiently accords with 
the brief character; and G. cercocarpoides does not appear to differ 
either.* 
The Composite afford two new genera, Hymenoclea and Baileya 
(Harv). A new Ash (Frazinus velutina) was found between the Del 
Norte and the Gila; and two new Zriogona. Quercus Emoryi is a new 
Oak from the same locality, and there are some new grasses. 
Dgopan (Cedrus Deodara). 
A friend had written to me to say that the name Deodar, though 
applied in Europe to the Cedar of the Himalaya, is incorrectly given to 
this tree, for that it belongs to the Cypress of the Himalaya (Cupressus 
torulosa). On enquiring the correctness of this statement of my enter- 
prising friend Dr, Thomas Thomson, he replies from Kashmir, in a 
letter dated Oct. 7th, 1848 (the c intelligence that has been received 
from him) to the following effect :— 
À still more remarkable shrubby Rosaceous (Dryadeous) plant than this, will be 
described by Mr. Bentham from Hartweg's Californian plants, n. 1712, the most 
singular plant perhaps of that collection. Its leaves are decompoundly pinnate 
with leaflets exceedingly small and resembling those of Azolla.
