Boxb., forming part of a new family indicated by Mr. Brown and 

 established by Dr. Blmne under the name of Pangiece), and Pi- 

 parea, AubL (long since determined by Mr. Brown not to be di- 

 stinct from Alsodeia); and adds to it, on the authority of Mr. 

 Brown, Xylosma, Forst., of which, as well as of Banara and 

 Prockia, he gives an amended character. Prockia serrata, Willd., 

 described by Swartz under the name of Lightfootia (a name pre- 

 occupied by 1/Heritier),he characterizes under the name of Thi- 

 odia ; and for the Prockia integrifolia and Prockia theaformis of 

 Willdenow, he adopts as a generic name the sectional name 

 Aphloia proposed by DeCandolle. To these species, which are 

 widely distinct from Prockia, M. Achille Richard gave about the 

 same time the generic name of Neumannia. 



The last article of the second part relates to a curious and in 

 some respects anomalous genus established by Dr. Blume under 

 the name of Polyosma, and by him referred to Caprifoliacece, but 

 afterwards placed by DeCandolle in his newly established family 

 of Cornea. Between this family and another previously esta- 

 blished by DeCandolle under the name of Alangiea, Mr. Bennett 

 believes the relation to be so intimate, that not even an artificial 

 distinction can be made between them. He compares Polyosma 

 with Cornus, Marlea and Alangium, and calls particular atten- 

 tion to the remarkable changes that take place in the ovarium of 

 Polyosma while the fruit is advancing to maturity ; that organ 

 being unilocular, and in the young state furnished with two pa- 

 rietal placentae, each supporting an indefinite number of ovules, 

 which are speedily reduced to a single ascending ovulum with 

 copious albumen and a superior radicle. Mr. Bennett confesses 

 his inability to reconcile these anomalies with the structure of 

 Cornea ; but states that he is " indebted to Mr. Brown for di- 

 recting his attention to another family, with the characters of 

 which, previous to the changes that take place in the ovarium 

 after impregnation, it fully agrees ; and to which, especially as 

 regards the structure of ovarium, a point of great importance, it 

 is certainly much more nearly related than to Cornea. Mr. 

 Brown proposes therefore to append Polyosma to Escalloniea, 

 notwithstanding its fruit reduced to a single seed, the large size 

 of that seed, and the increased proportion and firmer consistence 

 of its albumen. This approximation receives some confirmation 

 from its resemblance in habit to Anopterus, a genus strictly re- 

 ferable to that family." The characters of six species of the 

 genus are given ; three of them being from Java, one from the 

 hills adjoining Sylhet, one from Singapore, and one from New 

 South Wales.
