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

 imbricate and decussate bracts. Only one species is known. 1 



In the t\v r o American genera Ohrysochlamys and Tovomita, the 

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

 pyle directed downwards and outwards. Ohrysochlamys 2 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. 3 Some fifteen species 4 

 have been described. Tovomita, 5 abundant especially in the Antilles, 

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

 The stamens are free and have an 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 stigmatif'erous 

 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 Ohrysochlamys, the foliage of Clusia, with 

 numerous and generally small flowers, collected in umbelliform 

 cymes, solitary or gathered in a common ramified cluster. 7

3 The g. Tovomtiopsis (Pl. et Tri. he. cit. xiv. 

 261 -,—Sertolonia Spreng. N. Enid. ii. 110, t. 1, 

 fig. 1, not Mart.) has been distinguished on 

 account of its aril springing from the micropyle 

 instead of from the hilum. Bentham and 

 Hooker say : " Nos tamen in Chrysochlamide 

 arilli basin vidimus cum endocarpio et hilo 

 seminis tarn arete concretam ut funiculus nullus 

 appareat, et arillus cicatricis endocarpii v. semi- 

 nis oriri videatur," and they join Tovomitopsis 

 to the g. Chrysochlamis, to which they are in- 

 clined likewise to refer Commirhea Miers 

 {Trans. Linn. Sac. xxi. 252, t. 26).

1 We do not know to what group of this 

 family to refer the abnormal genus AllanblaoMa 

 (Oliv. B. H. Gen. 980, n. 15 a ; Fl. Trop. Afr. 

 i. 162), represented by a single species (A. 

 jlonhanda), which has the external characters 



of a Clusia or a Tovomita, but the stamens of 

 which are pentadelphous, with oppositipctalous 

 bundles, rudimentary in the female flower, and 

 the gymecium, rudimentary in the male, has a 

 unilocular ovary, with five parietal little-pro- 

 minent and multiovulate placenta;. The inflo- 

 rescence is in terminal compound clusters.
