The receptacle has the form of a small reversed cone. Around its base is a small calycinaU collar, very little developed and divided into four hard perceptible teeth, of which two are lateral, one anterior and one posterior. With these teeth alternate an equal number Gm-rya eiupuca. of valvate petals, much more developed, furnished with hairs above and with- out. The Andrcecium is composed of four altemi- petalous stamens, each formed of a filament and a basi-fixed,bilocular, introrse anther dehiscing by two longitudinal clefts. In the centre of the flower is a rudimentary gyntecium, composed of two very small carpellary leaves, sterile and lateral. In the female flower, the floral receptacle is hollowed to a sac and lodges in its cavity an adnate ovary, surmounted by a style also divided into as many erect or reflexedstigmatiferous branches as there are carpels in the gynsecium, that is most frequently two,^ which are lateral, and more rarely three. With the carpels alter- nate in equal number parietal placentae, more or less prominent, one anterior, the other posterior, when the number is two. In each is inserted a descending anatropous ovule, with micropyle directed upwards and out- wards,^ and hooded with a thick obturator forming the dilated funicle above it. The female perianth is absent as we shall find in the species (fig. 59) forming the genus Fadyenia.* Garrya Fig. 69. Long. sect, of female flower (^).
