168 NATURAL HISTORY OF PLANTS. 
part separates at anthesis into five teeth or five short lobes, or into 
a number of more or less deep equal or unequal divisions often fewer 
in number. Close against the calyx, and alternating with its 
divisions, are inserted five petals, slightly unsymmetrical, 
tapering at the base, arranged in the bud in contorted or imbri- 
cated præfloration. Above them the receptacle takes the form of a 
short cylindrical column, upon which the gynæceum is placed. 
Quite against this, that is to say, at a certain 
Brownlowia elata.  Jistance from the corolla, the androceum is in- 
im. serted, composed of ten bundles. Five are 
¥ VI oppositipetalous, and each represented by a 
sterile tongue or elongated petaloid staminode, 
and five others by phalanges of fertile stamens, 
free or scarcely united among themselves at the 
base of their laments, and with short anthers, 
-whose extrorse cells are almost globular, de- 
hiscing longitudinally by clefts often confluent at 
Fic. 177. the summit. The gyneceum is superior, formed 
Flower (2). of five or a smaller number of alternipetalous 
carpels. Each of them has a one-celled ovary 
touching the adjacent ovaries, but not united with them, tapering 
above into a subulate style with non-swollen stigmatiferous apex. 
In the internal angle of the ovary the placenta is seen supporting 
two ascending anatropous ovules with exterior and inferior 
micropyle. The fruit is formed of one, or more rarely of several 
independent almost globular carpels, with thick woolly bivalved 
monospermous pericarp. ‘The rounded seed, inserted by a large 
interior hilum, encloses under its glabrous coats a fleshy embryo, 
whose thick cotyledons are decurrent below their insertion and form 
a sort of case round the radicle. Brownlowia consists of beautiful 
trees of tropical Asia, besprinkled with scaly or stellate hairs. Three 
species have been described.” Their leaves are alternate, petiolate, 
simple, penninerved, and 3—5-nerved at the base. The flowers are 
disposed at the summits of the branches, or in axils of the upper 
leaves in ramified clusters of cymes.
