Oziroe Explained

Oziroe is a genus of bulbous South American plants in the squill subfamily within the asparagus family.[1] Within the Scilloideae, it is the sole member of the tribe Oziroëeae and the only genus in the subfamily to be found in the New World.[1]

Description

Species of Oziroe grow from bulbs, which have contractile roots as well as normal ones. Each bulb produces only a few leaves, which are thick and grooved. The flowering stem (scape) appears at the same time as the leaves. It has bracts along its length, with generally one or two flowers on straight stalks (pedicels) appearing from the angle between each bract and the scape. The flowers have six whitish tepals about 61NaN1 long which are joined for a short length at the base. Fertilized flowers produce black pear-shaped seeds up to 6– long.[2]
