large number of new species, the number of undescribed 

 genera is not great : Triplandron (Guttiferae), Pentagonia 

 (Rubiaceae), Oxypappus (Synantheraceae), Stemmadenia,

Purdie, a collector for the Kew Gardens, has reported 

 upon his travels in the West Indies (Lond. Journ. of 

 Bot., 1844, pp. 501-33). Among others he ascended 

 the peak of the Blue Mountains, in Jamaica, where the 

 forests of the summit consist of Podocarpus coriacea 

 (Yacca). In other respects these, as also Moritz's Bota- 

 nical Letters from Cumana and Caracas (Bot. Zeit., 1844, 

 pp. 173, 195, 431), merely give notices of the plants 

 collected. 



Miquel has continued his Contributions to the Flora 

 of Guiana (Linnaea, 1844) : some new Capparidaceae, 

 Sapindaceae, Malpighiaceae, Dilleniaceae, Leguminosae, 

 Melastomaceae (Hartigia, n. gen.), Memecyleae, Passi- 

 floreae, Onagrariae, Cucurbitaceae, Loranthaceae, Ru-

Richard Schomburgk, who accompanied his brother 

 during his last travels in British Guiana, has described in 

 his letters the botanical characters of the explored regions 

 (Bot. Zeit., 1844-5). We thus obtain an interesting 

 supplement to the previous work of Robert Schomburgk 

 on his travels, in which the botanical determination of 

 the plants was omitted, and which, now that a great part
