An extremely important systematic and illustrated 

 work, on the Flora of Java, which is now concluded, is 

 that published by Bennett and R. Brown from Horsfield's 

 herbarium (Plantae Javanicse rariores descriptse inconibus- 

 que illustrate. Descriptions et characteres plurimarum 

 elaboravit I. Bennett, observationes structuram, et affini- 

 tates praesertim respicientes passim adjicit, Rob. Brown, 

 pt. i, Londini, 1838 ; pt. ii, 1840; pt. iii, 1844). This 

 work contains 45 plates, and the following new genera: 

 Sclerachne and Polytoca (Graminacese), Hexameria (Or- 

 chidacese), Cyrtoceras (Asclepiadaceae), Stylodiscus (An- 

 draclme trifoliata Roxb.), Euchresta (Andira Horsjieldii 

 Lesch.), Mecopus and Phylacium (Leguminosse), Saocope- 

 talum (Anonacese), Lasiolepis (near Harrisonia Br.), 

 Pterocymbium (Sterculiacese), and several types from 

 other countries, which are elucidated in these copious 

 disquisitions. 



Junghuhn's diaries of his travels in Java, which have 

 been already alluded to, were indeed first published, with 

 additions, in 1845 (Topographische und naturwissenschaft- 

 liche Reisen durch Java, von F. Junghuhn, herausgege- 

 ben von Nees v. Essenbeck. Magdeburg, 8vo), but for the 

 sake of connecting them with the preceding Annual Report, 

 we think it better to report upon them now. In the western 

 portion of the island, as at Gede, the traveller found the 

 mountain-ridges covered far and wide on both slopes with 

 Rosamala-forests, i. e. with Liquid-ambar Altingiana Bl., 

 the stems of which are recognised even at a distance by 

 their tall straight growth and white colour, and which 

 overshadow a thicket of Scitaminese, Melastoma, Rubus, 

 and other shrubs (p. 165). A rich red soil here covers 

 almost the whole of the trachyte of Gede. According to 

 several measurements, the region of the Rosamala-forests 

 is situated at a level between 2000' and 4000' (p. 436) : 

 this tree, which is confined to the west of Java, occurs
