BOTANICAL GEOGRAPHY, 467 



collection from Texas; but I am unacquainted further 

 with the work. 



A. Richard and Galeotti intend publishing a monograph 

 of the Mexican Orchidacese, which will include 460 

 species ; of these about a third part are new. They have 

 published preliminary diagnoses of the new species (Ann. 

 Sc. nat., 1845, t. iii, pp. 15-33). V. Schlechtendal's 

 contribution to the flora of Mexico, for the present year, 

 refers to the Asphodeleae (Bot. Zeit., 1845). 



Purdie (Ann. Rep. for 1843) has continued his botani- 

 cal reports from Jamaica (Lond. Journ. of Bot., 1845, 

 pp. 14-27). 



The Cactacese, which are common on the south coast of the island, are 

 absent from the north side. In the former locality, at Bath, he found coast- 

 mountains about 3000' high, covered with a tall forest of Podocarpus Pur- 

 diena Hook., one of the largest forest-trees of Jamaica ; one of them, which 

 had been cut down, measured more than 100', 40' up to the crown, and at 

 the height of a man above the root, it was 3|' in diameter. Podocarpus 

 coriacea occurs above a level of 5000' or 6000'. The coffee-plantations are 

 situated on the south side of the island, e. g. at the pass from Kingston to 

 Bath, between 3000' and 6000'. Coffea does not thrive at a greater ele- 

 vation. 



Kuiize has enumerated and described the new species 

 among the Ferns collected by Moritz in Caracas (Bot. 

 Zeit., 1845, pp. 281-8). Of Bentham's descriptions of 

 Schomburgk's plants from Guiana, the Polygonacese 

 (14 sp.) and Thymeleacese (3 sp.) have appeared, as also 

 those of the Acanthacese (17 sp.) from Nees v. Esenbeck 

 (Lond. Journ. of Bot., 1845, pp. 622-37). Schomburgk 

 has himself described individual species of his collection 

 (ibid., pp. 12, 375). Gardner has published the diag- 

 noses of 100 new plants, discovered by himself in Brazil, 

 as a continuation of his former work (ibid., pp. 97-136). 

 K. Miiller has resumed the description of Gardner's 

 Mosses (Bot. Zeit., 1845, pp. 89 et seq.) The continu- 

 ation of Naudin's contributions to the flora of Brazil 

 (see the preceding Report) comprises the Melastomacese 

 (Ann. Sc. nat., iii, pp. ] 69-92, and iv, pp. 48-57).
