APPENDIX. No. V. 431 
Genera plantarum seems to have been aware. He probably, however, had not 
the metns 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 'Terebintacez, and which is proposed by M. 
de Jussieu himself, under the name of Cassuvi, consists of Anacardium, 
Semecarpus, Mangifera, Rhus and Buchanania, with some other unpublished 
genera. 
The perigynous insertion of stamina in Casswviw (or Anacardew) may be 
admitted in doubtful cases from analogy, there being an unpublished genus 
belonging to it even with ovarium inferum. And the oyarium, 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. 'Che 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nearly approaching in habit to two unpublished species of the genus from the 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. . 
AMYRIDEA, another family included in Terebintaceze, and to which the 
greater part of Jussieu’s second section belongs, may, like the former order, be 
considered as haying in all cases perigynous insertion of stamina; this structure 
being manifest in some of its genera. Of Amyridez, 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 Safw 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. 
CONNARACE4, is a third family which I propose to separate from 
Terebintaceze: 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, the pedicellus of the ovaria ; they may be con-
