In prefloration, all the Fig. 6 Seed (',«). Melastoma Fig. 3. Diagraiip. Fig. 5. Fruit. Fig. 7. Long. sect. of seed. stamens have the anther folded back upon the filament so that the summit faces the bottom of the flower occupying one of the small cavities between the base of the receptacle and that of the gynsscium.^ Between the stamens are seen the walls of separation between these small hollows which connect the receptacle with the ovary. The latter rises free throughout the rest of its extent, and supports a style surrounded by a sort of hairy ruffle,^ simple, finally curved and exserted, terminating in a small stigmatiferous cupule not enlarged. In the ovary are five alternipetalous cells, in the internal angle of which is inserted a large placenta with a short contracted support and ' Thia extremity looks directly dowBwards â¢when in the bud the anther is much inflexed at the top of the filament. Later it is quite superior, " In those of the Melastomacew where it has heen observed the pollen is described as " ellip- soid with three blunt ridges and six folds ; in water, oval or spherical with six bands, on three of which a ; (H. Mohl, Ann. Sc. Nat. ser. 2, iii. 332.) ^ The origin of these cavities, so common in this family, is that the development of the re- ceptacular tissue in those portions which bind it to the ovary cannot take place in those points occupied by the incurved anther. The bands which separate these cavities from each other are often called partitions, and there is indeed some analogy between the mode in which these partitions
