is perfectly straight. Prioria (near Copaifera) is described by 

 Grisebach, in ' i'lora of British West Indies.' Tlie fruit, un- 

 known to him, is figured by Mr. Bentham.

 Vol. V. (Bot.) p. 45. 



The apparent opposition of the stamens to the petals in the 

 trimerous, dimerous, and tetramerous species of the Order (as also 

 in Berlerideae) is due to the circumstance that the petals and 

 stamens are each usually in two whorls, — the outer stamens 

 being opposite to the outer petals, the inner stamens to the 

 inner petals. A synopsis of the sufficiently known genera of 

 American, tropical, cocculoid Menispermaceae is given, followed 

 by general observations upon each genus. 



■ Notes on Tiliaceae. p. 52. 



Mr. Bentham, with Dr. Hooker, adopt 37 genera, which are 

 disposed vmder 6 tribes, grouped into 2 suborders, — JSolopetalae, 

 characterized by the petals, which are always of petaloid nature, 

 being always present (except in one or two Grewias), narrowed 

 at the base and deciduous ; and Heteropetalae, marked by petals 

 when present being more or less sepaloid, attached by a broad 

 base and usually persistent. 



A synopsis of the Tribes is given, followed by critical obser- 

 vations upon the Genera. New species of Liihea and Mollia are 

 described from Spruce. The species of Sloanea are diagnosed, 

 some new species of Spruce's being described at length. Of the 

 genus EcJnnocarpus, Bl. five new species are described from 

 N. E. India, and one from Australia. 



Notes on JBixaceae and Samydaceae. p. 75. 



Tlie authors of the new ' Genera Plantarum ' propose to 

 unite Decandolle's Orders Bixaceae and FlacourtiacecB, Samydeae 

 and Homalineae into two Orders, viz., Bixaceae with hypogy- 

 nous, and Samydaceae with perigynous stamens. Baiiera is 

 referred to the latter Order. A synopsis of the Tribes of each 

 Order is given with anenumerationof their included genera, upon 

 many of which critical observations are added, with descriptions 

 of new and imperfectly known species.
