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.
