. The natural history of plants. Botany. Kg. 39. Diagram. five or six valvate or imbricate divisions, and as many alternate petals contorted in the bud. The stamens, double the petals in number, and disposed in two verticils, have free filaments, rather thick, or more slender in the species forming the genus Topohea} In the latter the anthers are more elongate and narrower, while in Blakea proper they are shorter and wider, dolabriform, with linear cells, corresponding to the internal mar- gin of the connective, but facing outwards when the anther is in- flexed on the summit of the fila- ment, and dehiscing by pores or short clefts. The base of the con- nective is blunt or prolonged in a more or less prominent spur facing upwards in the bud. The summit of the anthers at this period moulds itself in the superior cavity of the depressed ovary which is sometimes covered with a thin glandular layer, belonging to a disk which terminates at the insertion of the filaments. The ovary is adherent in its entire extent and sometimes prolonged at its centre in a conical projection, surmounted by the style. The latter is simple, columniform, with truncate or capitate stigma- tiferous extremity, entire or slightly lobed. The ovary is divided into four, five, or six cells, in the internal angle of which is a placenta covered with anatropous ovules; it becomes a fleshy, spongy, or coriaceous indehiscent fruit, enclosing an indefinite number of ovoid, oblong, or subpyramidal seeds, with salient raphe and fleshy embryo, without albumen. Blakea consists of shrubs, glabrous or hairy, erect or climbing, with opposite leaves, often large, sometimes very Sellucid Rg. 40. Long. sect, of flower. 1 AuBL. Gmm. i. 476, t. 189.—J.
