This genus has been placed in different families, particularly in the series of Melastoma- cece, of I/ythrariacecB, and it has also been con- sidered (AitNOTT,âNaudin) as the type of quite a distinct family. i> Butt. Soc. Linn. Par. (1876) 90. We have seen in tracing the development of the flowers of this genus (fig. 425, 426), that they have a hollow tubular receptacle, to the bottom of Olinia Fig. 425. Flower (}). which the ovary is adnate, and at the upper orifice of which are inserted four or five coloured sepals, as many small alternate petals, super- posed to which are an equal number of stamens, â with short bilocularintrorse anthers, surmounted by a glandular connective. The cells of the inferior ovary, 3-5 in number, contain each 2 or 3 ascending ovules with micropyle exterior and inferior. Decaisnb (Tr. Gen. Botan. 292) has described and figured the ovules as pendant, a grave error. The fruit is drupaceous, and the putamen encloses a seed with exalbuminous embryo, and the cotyledons are said to be un- equally convolute. It is by this character especially that the OlinietB are distinguished as a tribe or series in the family of Shamnacea, where we propose to place them. The short collarette, entire or obs
