形態特徵

• Herb, reddish, glabrous. Stems slender, simple, rarely branched, 4-12 cm long, 0.5-1.5 mm in diameter.
• Scales ovate or narrowly ovate, acuminate, 2-4 mm long.
• Racemes erect, 3-9-flowered. Flowers unisexual (pistillate flowers towards the base, staminate ones towards the apex), short-pedicellate; perianth-segments 6, equal, subulate, 2-3 mm long, glabrous; stamens 3 or 2, subsessile; ovary numerous, clustered, obovate, 0.5 mm long, upper part papillate; style inserted basally, clavate, apex papillate; carpel clavate-obovate, ca. 1 mm long, apex rotund.
• <i>Sciaphila megastyla</i> Fukuy. & T. Suzuki was distinguished by Fukuyama and Suzuki (1936) from <i>S. tosaensis</i> Makino in having a distinctly exserted style from the ovary. However, this character seems to be variable and continuous between the two. These two species are characteristic in having a clubshaped style with many papillae at the apex. In this point both are identical with <i>S. secundiflora</i> Thwaites <i>ex</i> Benth., which was regarded to be close to <i>S. tosaensis</i> when it was published.
