398 NATURAL HISTORY OF PLANTS. 



has all the stamens united in a solid mass, in which are imbedded 

 the anthers, sometimes but slightly projecting at the exterior. These 

 anthers open sometimes by pores and oftener by longitudinal, lateral 

 or introrse clefts. Thus constituted, ^ the genus Clusia comprises 

 some sixty species.^ They are trees or shrubs with gummy resinous 

 latex, often yellow ; they are ordinarily glabrous, sometimes sarmen- 

 tous and climbing, often living as parasites (true or false) upon the 

 trunks of trees, which they finally kill.^ The leaves are opposite, 

 without stipules, thick, coriaceous, entire, penninerved, with a single 

 visible median nervure or with five parallel nervures in great 

 number. The flowers are terminal or solitary, or in cymes. Under 

 the calyx are two bracts, or a larger number of decussate-alternate 

 folioles which mingle imperceptibly with the sepals. All belong to 

 the warm regions of America, from Mexico to Paraguay. 



Beside Clusia is placed Quapoya^ (fig. 361-366), which differs 

 from it in the definite number of stamens, and also in the arrange- 

 ment of the two vertical series of ovules, sometimes few and 

 ascending,^ sometimes more numerous and transverse or nearly so. 

 In the prototype of the series, Q. scandens, there are ten stamens 

 united by their filaments to a common tube, at the bottom of which 

 is seen a rudimentary gynsecium. The obcuneiform anthers are 

 free almost only at the summit of the tube, and present two linear 

 and marginal cells (fig. 361). In other species of the same genus, 

 to which the name Bengifa ^ has been given, there are from five to 

 ten stamens, the filaments of which are all likewise united in a 

 shorter tube, except at the summit, which may be independent. The 

 anthers are formed like those of Q. scande7is, and the number of
