112 BOTANY OP CONGO. 



bably, hov/ever, had not tlie means of ascertaining all their 

 distinguishing characters, and therefore preferred leaving 

 the order nearly as it was originally proposed by Bernard 

 de Jussieu in 1759. 



One of the orders included in Terebintaceae, and which 

 is proposed by M. de Jussieu himself, under the name of 

 Cassuvi^, consists of Anacardium, Semecarpus, Mangi- 

 fera, Rhus, and Buchanania, with some other unpublished 

 genera. 



The perigynous insertion of stamina in Cassuvim (or 

 Anacardece) may be admitted in doubtful cases from 

 analogy, there being an unpublished genus belonging to it 

 even with ovarium inferum. And the ovarium, though in 

 all cases of one cell, with a single ovulum, may, at least in 

 those genera in which the style is divided, be supposed to 

 unite in its substance the imperfect ovaria indicated by the 

 branches of the style, and which in Buchanania are actually 

 distinct from the complete organ. The only plant belong- 

 ing to this order in the herbarium, is a species of Rhus, 

 virith simple verticillate leaves, and very nearly approaching 

 in habit to two unpublished species of the genus from the 

 Cape of Good Hope. 



AMYRIDE^, another family included in Terebintaceae, 

 and to which the greater part of Jussieu's second section 

 belongs, may, like the former order, be considered as 

 having in all cases perigynous insertion of stamina ; this 

 structure being manifest in some of its genera. Of Amy- 

 ridese, there are two plants in the collection. The first of 

 these is a male plant, probably of a species of Sorindeia •} 

 the second, which is the 8afu of the natives, by whom it is 

 cultivated on account of its fruit, cannot be determined 

 from the imperfect state of the specimens ; it is, however, 

 probably related to Poupartia or Bursera. 



CONN ABAC E^, is a third family which I propose to 

 separate from Terebintaceae : it consists of Connarus Linn. 

 Cnestis Juss. and Rourea of Aublet or Robergia of Schre-
