204 Bibliography. 



the account of the Cahfornian collections, which, following the order 

 of De Candolle's Prodromus, extends to Paronychiacese, does not em- 

 brace a single addition to the species already described in Torrey & 

 Gray's Flora of North America, which comprises Upper California 

 alone ; while the collections south of that limit were mostly new as to 

 species, which almost exclusively belong to tropical or Mexican forms. 

 There Cactacese and Euphorbiacese prevail, Malpighiaceae and Bursera- 

 cese make their appearance ; and the Mangrove with its companion the 

 Laguncularia m.ake their appearance on the shores ; their northern limit, 

 being the Bay of Magdalena, in lat. 24° 38'. The plant doubtfully re- 

 ferred by Hooker and Arnott to Vitis Caribcea, is here characterized 

 as a distinct species under the name of V. Calif ornica.

6. Sertwn Planiarum, or Drawings and Descriptions of Rare or 

 Undescrihed Plants, from the aiit.hor''s Herbarium ; by H. B. Field- 

 ing, F. L. S. and R. G. S., assisted by George Gardiner, F. L. S. 

 London, Bailliere, Part I, 8vo. — This work is on the same plan as 

 Hooker's excellent Icones Flantarum ; the figures being executed in 

 neat lithography, and each with a single page of descriptive letter-press. 

 Four parts are announced, each to comprise, like the one before us, 

 twenty five plates ; but as Mr. Fielding's truly rich herbarium, (found- 

 ed on that of the late Mr. Prescott, of St. Petersburgh and enhanced 

 by the choicest portions of the late Mr. Lambert's collections, and from 

 many other sources,) will long furnish a series of most appropriate and 

 important subjects for illustration, we trust his zeal will lead him to 

 continue the work. Among the more remarkable plants here figured, 

 we notice Acacia smilacifolia, with phyllodia simulating the leaves of 

 a Smilax ; and the Brazilian Passijlora speciosa, with bright scarlet 

 flowers five or six inches across. The only North American species 

 is Silene Nuttallii, Torr, & Gr., from Drummond's Texan collection.

7. Cours Elementaire de Botanique, par M. Adr. de Jussieu. Paris, 

 Part 11. pp. 227-728, 18mo. — The rapid multiplication of elementary 

 works upon botany of an increasingly excellent character, afl^ords a 

 just indication not only of the actual progress of the science in the 

 hands of a few devotees, but of the zeal and thoroughness with which it 

 is now generally pursued, and of the rank which it is beginning to hold in 

 a liberal education. We should like to commence the study of botany 

 anew, with this volume of Jussieu for a text-book. In a small com- 

 pass, and in a treatise of a really elementary character, he has given 

 the most complete and lucid exposition of the science that we have
