APPENDIX. No. V. 431 



Genera plantarum seems to have been aware. He probably, however, had not 

 the means of ascertaining all their distinguishing characters, and therefore pre- 

 ferred 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.e, consists of Anacardium, 

 Semecarpus, Mangifera, Rhus and Buchanania, with some other unpubhshed 

 genera. 



The perigynous insertion of stamina in Cassuvicc (or Anacardea) may be 

 admitted in doubtful cases from analogy, there being an unpublished genus 

 belonging to it even vith ovarium inferxun. And the ovarium, though in all cases 

 of one cell, \vith 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 belonging to this order in 

 the herbarium, is a species of Rhus, with simple verticillate leaves, and very 

 nearly approaching in habit to two unpublished species of the genus from the 

 Cape of Good Hope. 



AMYRIDEv^, another family included in Terebintaceae, and to which the 

 greater part of Jussieu's second section belongs, may, hke the former order, be 

 considered as having in all cases perigynous insertion of stamina ; this structure 

 being manifest in some of its genera. Of Amyridea*, 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 Sufu of the natives, by whom it is cul- 

 tivated 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.^RACEjE, is a third family which I propose to separate from 

 Terebintaceas : it consists of Connarus Linn. Cnestis Juss. and Rourea of 

 Aublet or Robergia of Schreber. The insertion of stamina, in this family, is 

 ambiguous ; but as in a species of Cnestis from Congo, they originate from, 

 or at least firmly cohere with, (he pediceUus of the ovaria ; they may be con-
