Evergreen subshrub, hermaphrodite, generally upright, up to 1.5 m in height, very ramose. Fertile branches, herbaceous, are born opposite and are articulated, cylindrical, green and glabrous, seemingly without leaves. First segment of the branches \u00b1 flattened and angled, the following segments \u00b1 cylindrical. Leaves opposite, sessile, very small, forming a hyaline ring that surrounds the branch segment at the apex. Inflorescence a cylindrical and articulated spike (20-50 mm in length \u00d7 3-5 mm in diameter). Flowers grow in tri-floral cymes located at the base of the branch segments. The central flower is always slightly larger than the lateral ones; perianth with only one part (actually, 4 fused tepals, circular in cross section); anthers yellow 1-1.3 mm, style 0.4-0.7 mm. When flowers fall they leave a single cavity, not partitioned by membranous walls. Fruit an achene with a black and verrucous seed.<\/p>\n","protected":false},"featured_media":0,"template":"","class_list":["post-11946","species","type-species","status-publish","hentry"],"acf":[],"yoast_head":"\nArthrocaulon macrostachyum (Moric.)
