On either side of the walls of the ovary is seen a pair of wings,^ which become more marked in the fruit; this has not yet been studied at maturity. D. orc/iidaceaj' the only known species, is a lofty tree from the west of tropical Africa. Its alternate imparipinnate leaves have two lateral stipules. The flowers, which in form and colour recall those of certain Orchids, are collected in terminal racemes.' Next to this we shall place Moldenhauera,'* referred by some to Sclerolobieee, from which, however, it is distinguished chiefly by the convexity of its receptacle, and by the hy- pogynous insertion of the perianth and androceum resembling that of Baudouinia, Martia, and Duparquetia. The flowers are pentamerous or tetramerous (fig. Ill), with valvate sepals, at first sticking to- gether by their edges and then becoming quite free down to the receptacle, unguicu- late petals whose limbs are fringed and lobed, auricled at the base, and much imbri- cated in the bud, and two whorls of four or five free stamens, superposed the one to the sepals, the other to the petals ; the anterior stamen, corresponding with the back of the carpellary leaf, is enormously developed. Its filament is incurved and ends in a fertile or sterUe anther with a thick connective often covered with hairs. The other seven or nine have short erect filaments, and flattened sub-basifixed anthers, which dehisce near the apex by a cleft prolonged downwards to an extent varying with the genus, but which may be very short, as in Cassia. The ovary is superior sessile and multiovulate, surmounted by a slender style, inflexed or involute in the bud, with a slightly dilated or capitate. Pia. 111. Flower (A).
