A very showy and handsome plant, and cultivated for this reason not only in 

 Mexico but in many other regions. In general appearance it suggests Bougam- 

 villea, and is equally handsome. It is a rapid grower and remains in bloom a 

 long time. In Florida it is known as " Confederate vine." The flower clusters 

 serve as tendrils for the support of the plant, and shorten themselves by bending 

 at the joints in a zigzag form. The roots bear tubers which are usually small, 

 although they are said sometimes to weigh as much as 15 pounds. They are 

 edible and have a nutlike flavor. For an illustration of this species see Contr.

Beibl. 80: 14. 1905. 

 Yucat&n and Chiapas ; type from Progreso, Yucatan. 



Shrub or tree, sometimes 12 meters high ; leaves obovate to oval, 2 to 5.5 cm. 

 long, rounded at apex, puberulent when young; flowers fasciculate, racemose, 

 greenish, the sepals in age 7 mm. long. 



The Chiapas specimens liave slightly broader and larger leaves than those 

 from Yucatan.

 Leaves broadly ovate, 5 cm. long, acutish.

 1. Triplaris auriculata Meisn. in DC. Prodr. 14: 174. 1856. 



Chiapas and perhaps elsewhere in .Mexico, the type from some unknown 

 locality. 



Shrub or tree, more or less pubescent ; leaves large, oval, short-petiolate ; 

 flowers dioecious, racemose, the pistillate calyx accrescent and in fruit about 5 

 cm. long. 



The Mexican material seen appears to be the same as T. uincomhii Donn. 

 Smith, and is perhaps not different from T. surinamcnsis Cham. T. auriculata 

 is probably the plant reported from Chiapas as Triplaris sp. with the vernacxilar
