mingia strobilifera, of Zornia, and of Geissaspis, and points out 

 the curious modifications which occur in each in the origin of 

 their bracteaj and in the mode of their a])phcation to the protec- 

 tion of the fruit. Phylacium differs from all other Hedysareous 

 genera in its climbing habit, by means of which, as well as in 

 some other characters, it approaches Phaseolea. 



Parochetus maculatus, the subject of article thirty-four, is a 

 pretty species of a Papilionaceous genus founded by Buchanan 

 Hamilton, and described in Don's ' Prodromus Florae Nepalen- 

 sis,' the immediate affinities of which do not appear to have been 

 yet satisfactorily made out. 



Saccopetalum Horsfieldii is described by Mr. Bennett as con- 

 stituting a new genus of Annonacea, and forming with Miliusa, 

 Lesch., and Hyalostemma, Wall., part of a well-marked tribe of 

 that family, characterized by its 3-sepalous calyx, with the three 

 petals of the outer series free and sepaloid, and the three of the 

 inner series cohering valvularly at their edges ; the cohesion being 

 so complete and continuing to so late a period as to have induced 

 M. A. DeCandolle and Dr.Wallich to describe Miliusa and Hya- 

 lostemma as gamopetalous. These genera are compared with Sac- 

 copetalum in reference to their more important organs ; and va- 

 rious particulars of structure in other genera of the family are 

 discussed with reference to their arrangement, distinction and 

 relations with each other. 



In the two succeeding articles Mr. Bennett describes two spe- 

 cies of the genus Saurauja of Willdenow, S. bracteosa, DeC, and 

 S. Blumiana. On the subject of these plants he enters into an 

 examination of their claim to be placed in the family of TernstrK- 

 miacecB, which (notwithstanding their wide discrepancy from Tern- 

 strcemia itseK) he is constrained to admit. He calls attention to 

 a remarkable tubular prolongation of the endostome, or that por- 

 tion of the inner membrane of the seed sm-rounding its aperture, 

 which fills up the aperture of the testa like a cork in Saurauja 

 and other Ternstroemiaceous genera ; and particularly notices the 

 great abundance of acicular crystals or raphides produced between 

 the testa and the inner membrane in Saurauja. 



The thirty-eighth article has for its subject a very pretty genus 

 of the order Meliacece, to which Dr. Wight has given the name 

 of Munronia. The species here figured is described by Mr. Ben- 

 nett as the Munronia Javanica. One of the plants belonging to 

 this genus was described and figured by Dr. Wallich under the 

 name of Turrata pinnata ; and this gives occasion to Mr. Bennett 

 to enter at length upon the history of the genus Tuircea ; to ex- 

 amine its characters, comparatively with those of Munronia ; and 

 to give a synopsis of the two genera, vfiih. descriptions of several 

 new species. These genera, together with a nearly related genus
