ovules whose micropyles look upwards and outwards; it is sur- 
mounted by a tapering style, obtuse at the stigmatiferous apex. 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. orchidacea, the only known species, is alofty 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 
Sclerolobiee, 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. 111), 
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, isenormously developed. Its 
filament is incurved and ends in a fertile Fie. 111. 
or sterile anther with a thick connective aren ey 
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 
Moldenhauera emarginata.

separating the two posterior wings. ducous lateral bracts.
