in short cymes (?), are accompanied by from two to four pairs of 

 imbricate and decussate bracts. Only one species is known,' 



In the two American genera Chrysochlamys and Tovomita, the 

 ovarian cells are uniovulate, and the ascending ovule has its miero- 

 pyle directed downwards and outwards. Chrysochlamys ^ has four 

 or five sepals and from four to ten imbricate petals. The stamens 

 are numerous, sometimes partly sterile, and free or united at the 

 lower part of their short filaments. The fruit, at first somewhat 

 fleshy, finally becomes a septicidal capsule with five valves. The 

 seeds are surrounded by an incomplete fleshy aril, open at the back 

 and of which the point of origin is variable.^ Some fifteen species * 

 have been described. Tovomita,^ abundant especially in the Antilles, 

 Guyana, and Brazil, has nearly the same perianth, with 4-10 petals. 

 The stamens are free and have aa erect, linear-subulate filament, 

 surmounted by a very small anther. The ovary, with four or five 

 cells, is surmounted by an equal number of distinct stigmatiferous 

 heads, nearly sessile or supported .each by a moderately long stylary 

 column. The dehiscent fruit contains seeds described as destitute of 

 aril, but in reality the entire superficial coat is transformed into 

 arillar tissue. Tovomita, of which some score of species ^ have been 

 distinguished, has^ like Chrysochlamys, the foliage of Clusia, with 

 numerous and generally small flowers, collected in umbelliform 

 cymes, solitary or gathered in a common ramified cluster.'
