Biarum
(an ancient name of a plant). ORD. Aroideae. A genus of small, hardy, tuberous-rooted perennials, much more curious than pretty, allied to Sauromatum. This genus, according to Dr. Masters, differs from Arum in its spathe being tubular at the base, with the limb spreading. The female flowers have a distinct style, and the fruit contains only one ovule. They will thrive in any light, rich, well-drained soil, and may otherwise be treated similar to the hardy Arums. There are several other species besides those named, but they are not yet in general cultivation.
B. constrictum (constricted). A synonym of B. tenuifolium.
B. gramineum (grassy). A synonym of B. tenuifolium.
B. tenuifolium (slender-leaved).* fl., spathe dark brown-purple, reflexed in the upper part; spadix very long, subuliform. June. l. linear-lanceolate. h. 6in. South Europe, 1570. SYNS. B. gramineum and B. constrictum. (B. R. 512, under name of Arum tenuifolium.)
