2. Enargea, Banks and Sol.

Glabrous almost suffruticose herbs. Stems slender, branched,. wiry, knotted at the joints, lower joints with small membranous scales. Leaves alternate, sessile or nearly so, distichous, lanceo-late to oblong, prominently nerved. Flowers white, solitary or 2–4 in the axils of the leaves. Perianth deciduous; segments 6, dis-tinct, subequal, spreading, thin, nerveless. Stamens 6, hypogy-nous; filaments erect; anthers linear-oblong, basifixed, longitudi-nally dehiscent. Ovary sessile, ovoid, 3-celled; ovules 4–10 in. each cell; style filiform; stigma terminal, capitate or obsoletely 3-lobed. Berry subglobose, indehiscent. Seeds few, ovoid or sub-globose; testa thin, appressed; embryo short, straight; albumen-horny.

In addition to the New Zealand species, which appears to be the same as the Fuegian and Falkland Island E. marginata, there are two others from Chili. I agree wilh the late Baron Mueller (" Victorian Naturalist," December, 1886) in considering that Enargea should take precedence over both Callixene and Luzuriaga. Enargea was published by Gaertner from Solander's notes in 1788, whereas Gallixene did not appear until 1789, and Luzuriaga in 1802. Enargea appears to have been rejected on account of an error in Gaertner's plate, but that does not seem to be a sufficient reason for setting aside the name.
