Pistacia vera. 



1. SPONDIAS SEEIES. 



PistacUa terehinthus (Fr. T&ebintlie), from wMoh. this family- 

 derives its name, belongs to tlie genus Pistacia (fig. 259, 314-317) ; 

 but this is far from being tbe most complete type known, tbat being 

 only found in tbe Spmdias^ (fig. 260, 261), and some closely allied 

 genera. The flowers are regular, 

 hermaphrodite or polygamous, with 

 four or, more often, five parts. 

 In the latter the convex receptacle 

 bears from below upwards : a calyx 

 with five divisions, more or less 

 deep, imbricate in the bud; five 

 alternate petals, valvate or slightly 

 imbricate on the feather-like edges, 

 and ten stamens superposed, five 

 to the divisions of the calyx and 

 five to the petals. They are each 

 formed of a free filament, inserted 

 outside the base of a large flve- 

 lobed disk, and a bilocular introrse 

 anther dehiscent by two longi- 

 tudinal slits. Inside the disk is 

 found a gynseceum with five oppo- 

 sitipetalous carpels ; they are united, sometimes, it is true, to a 

 very slight extent, in their ovary ; whilst the style is free, marked 

 in the interior by a mesial groove, longitudinal, and more or
