subject a Javanese genus, nearly related to Brucea, and called 

 Picrasma by Dr. Blume. Mr. Bennett points out the differ- 

 ences between this genus and Brucea, and adds to it a Ncpau- 

 lese species doubtfully referred to Brucea in Dr. Wallicli's List. 

 He regards also as belonging to Picrasma, but forming a sub- 

 genus, Nima qiiassioides of Buchanan Hamilton, which Don had 

 refen'ed to Simaba. He notices several plants that have been 

 from time to time regarded as either actually belonging to Bru- 

 cea, or at least as very intimately related to it. Of these Lepta 

 and Tef radium, two obscure genera of Loureiro, A\diich have been 

 singularly bandied about by systematic writers, are proved, by 

 the examination of specimens from Loureiro himself, to belong 

 to Xanthoxijlum, including in that genus Fagara, as proposed by 

 M. Kunth. Xanthoxylum Clava Herculis of Loureiro (not of 

 Linnseus) is shown on the same authority to belong to a genus 

 distinguished from Xanthoxxjlmn by the want of sterile stamina 

 in its female flowers, and its subsessile peltate stigma surmount- 

 ing two collaterally biovnilate ovaria. Ailantus gracilis of Salis- 

 bury, referred by DeCandolle to Brucea, is proved by a speci- 

 men from Salisbury himself not to be distinct from Brucea Su- 

 matrana, Roxb. With regard to the position of Brucea and Pi- 

 crasina in the natural system, Mr. Bennett ventures doubtfully to 

 suggest their approximation to Simarubece, but professes himself 

 far from satisfied with respect to their real affinities. 



Lasiolepis paucijuga, together with a second species, L. multi- 

 juga, collected by INIr. Cuming in the island of Mindanao, form a 

 new genus, which appears to Mr. Bennett to be closely related 

 to Harrisonia, R. Br., and to have no other near affinity. These 

 two genera are also, as M. Adi-. de Jussieu has already observed 

 of Harrisonia, most nearly related to SimarubecE, although not so 

 closely as to admit of their being absolutely referred to that order. 



Pangium edule, Eeinw., a tree of great importance in the domes- 

 tic oeconomy of the Malays, and abundantly cidtivated through- 

 out the Malayan islands, has hitherto been botanically kno\Mi 

 only through the character of the genus published by Professor 

 Reinwardt, and by the proposal of Dr. Blume to found on it a 

 family to be named Pangiea, in which he includes the genera 

 Hydnocarpus and Vareca of Gsertner. This family was some 

 years ago indicated by Mr. Brown in a verbal communication to 

 ]\I. Zuccarini, in which he referred Hi/dnoca7-pus and G?jnocar- 

 dia, Boxb., to a distinct family then unnamed. Of this family, 

 and of the three genera Pangium, Gynocardia and Hydnocarpus 

 (all of which are referred by Prof. Endlicher to Hydnocarpus), 

 Mr. Bennett gives detailed and distinctive characters. He agi-ees 

 with Roxburgh in referring Vareca, Ggertn., to Casearia; and 

 states that the three species of which Roxburgh has composed
