bricated' or contorted in the bud. The stamens are indefinite in 
number, sometimes pretty considerable, often also only from ten to 
eight. Their filaments are short, united into a sort of thick tube, 
widely cleft on the anterior side of the flower, so that the androceum 
only surrounds the gynæceum behind. The anthers are elongate- 
linear, basifixed, two-celled, divided into four 
secondary cells separated by longitudinal 
grooves; they open almost at the summit by 
two pores or short clefts. The gynæceum is 
composed of a superior ovary slightly ex- 
centric, tapering at the summit into a subu- 
late style with simple stigmatiferous apex. In 
the ovary are seen two, three, or five parietal 
placentas, more or less prominent in the in- 
terior of the cavity, and bearing on their 
reflexed edges’ a number of anatropous, im-

septicidal capsule, divided at maturity imto 
three or five valves, often leaving upon the receptacle, from which 
they detach themselves, woody bands corresponding to their edges. 
The seeds are small, numerous, attached within towards the edge of 
the valves. Their outer coat is more or less dilated in the form of 
a wing; and their inconsiderable, fleshy albumen surrounds a cylin- 
drical embryo.

Their cylindrical branches are loaded with alternate simple, petio- 
late, coriaceous, smooth serrulate leaves, often ciliate upon the edges 
and summit, penninerved, with parallel secondary nerves, fine, close, 
generally subperpendicular to the midrib, with two lateral ciliate 
stipules. The flowers‘ are disposed in simple terminal racemes, each 
supported by an articulate pedicel at the base, accompanied by two 
lateral bractlets. 
Beside this genus are placed several others, which all belong to the
