the two Americas, with rather large and showy flowers in terminal 



or axillary clusters of cymes. 



Rondeletia, a name given also to a tribe of EuUacea, is placed at 



the head of a subseries with capsular fruit, seeds generally without 



or with very short wings, as in all the preceding types; but with. 



corolla strictly imbricate instead 



of valvate. Its lobes are nor- 

 mally four or five in number. 



The tube is generally thickened 



at the throat beyond which the 



anthers do not pass. The fruit 



is loculicidal, and the valves 



may separate. The seeds are 

 very variable in form, cubical, 

 or angular, or fusiform, or com- 

 pressed and even winged. They 

 are trees or shrubs of tropical 

 America with opposite or temate 

 leaves and flowers in terminal 

 clusters of cymes. BhacJdcallia 

 mpestiis has the tetrameroiis 

 flowers of Rondeletia, but they 

 are solitary and axillary. It is 

 a small shrub from the maritime 

 rocks of the Antilles, with small 

 whitish fleshy leaves and sti- 

 pules united in an enlarged and 



ciliate sheath. The fruit is capsular, partly superior, and septicidal. 

 Bathysa has also a septicidal capsule. They are Brazilian trees or 

 shrubs, often downy. The small flowers are terminal, in ramified 

 clusters of cymes, 4, 5-merous, with short corolla, imbricate or 

 contorted, and exserted stamens inserted at the mouth of the corolla. 

 The seeds are angular, compressed or bordered with a narrow 

 rudimentary wing. 



Wendlandia is the old world analogue of the American Rondeletia. 

 It has the imbricate, or oftener perhaps contorted corolla of 4, 

 5-divisions ; stamens inserted near the mouth of the corolla ; an 

 ovary with two mUltioVulate cells, surmounted by a style the 

 stigmatiferous extremity of which, enlarged or claviform, is bilobed
