Close beside Dichapetalum are placed two geuera very closely allied 

 to it: Stejilianopodium^ {^g,. 22Ç)\ distinguislicd principally by tbe 

 petals being united, sometimes for a very great 

 distance in a gamopetalous corolla bearing the sta- 

 mens; and Tapiira'^ (fig. 227 

 -229), also having a gamo- 

 petalous corolla, but irre- 

 gular, imbricated and with 

 fertile stamens, generally 

 fewer, more rarely equal in 

 number to the divisions of 

 the corolla.-^ The disk is 

 unilateral. The two last 

 genera have alternate

 as the summit of the petiole. The fii-st has only American species,

' This has only been seen at present in one 

 American species, T. capitiili/ei-a, the type of our 



section LiscIilzoUcnn. The meiostemonous spe- 

 cies have usually three fertile stamens, alternate 

 with the two large double-headed petals ; the 

 others are sterile. The plane of symmetryjpass- 

 ing by the middle of sepal 2 and in the] inter- 

 vals f sepals 1 and 3, cuts at an angle of 1/lOth 

 of the circumference the plane of symmetry of 

 the corolla (fig. 228), the androceum and the 

 gynasceum. (See Adansoiiia, xi. Ill, 112).
