Stipules triangular to long elliptic, 3.5–11.8(–16) by 1.3–1.5 mm, outside stellately hairy, inside sericeous with simple hairs, basally 2 glands outside. Leaves red then yellow when young; petiole (not of the subsessile upper leaves) (0.3–)5–20.4 cm long, round except basally flattened above, longitudinally grooved when dry, stellately hairy, apically two or more glands, the largest on spreading stipellae; blade ovate to elliptic, 9–41 by 3.3–20 cm, length/width ratio 2–2.7, basally emarginate to rounded to widely cuneate, margin entire, revolute, apex cuspidate, upper surface dark green, drying greenish; lower surface pale green, drying brownish green, venation slightly raised above, strongly raised underneath, nerves 9–12 pairs, tertiary veins ± scalariform, quaternary and higher order veins reticulate. Inflorescences terminal, 3.5–24 cm long, reddish, staminate part very condense, separate nodes usually not well visible; lowest bracts often leaf-like, usually (sub)sessile, base emarginate; higher bracts triangular, stipule-like, 3–9 by 1.8–4 mm, completely stellately hairy; bracteoles like bracts, smaller. Flowers pink to red, slightly fragrant. Staminate flowers 6–7.5 mm diam.; sepals ovate to round, 3–4.2 by 2.3–3.3 mm, outside stellately hairy, inside glabrous; stamens 8–10, filaments long, slender, folded in bud, tapering towards the apex, 7–10 mm long, glabrous, white, anthers 1.5–2.8 by 1–1.3 mm, yellow, with stellate hairs, one theca generally larger than other; pistillode 0.8–2 by 0.3–0.5 mm. Pistillate flowers 6–21 mm in diameter, ; pedicel 2.8–3.5 mm long, very sturdy, grooved when dry; epicalyx elements usually present (sometimes absent on Sumatra), ovate to triangular, 3.6–4.8 by 1.2–1.8 mm, margin with inconspicuous glands; sepals 6, ovate-elliptic, 5–9 by 1.8–4 mm, midrib thickened; ovary ovate, 3-lobed, 2.5–3 by 2–2.5 mm, style 4–8 mm long, crimson-rose, stigma up to 10 mm long, first split at 2/3rd of style, apically splitting twice to several times more. Fruits 15–20 mm high by c. 16 (1 lobe developed), 19–30 mm wide, red to pink-red; pedicel up to 4.8 cm long, sepals ovate, 2.9–5 by 1.4–3.4 cm, dark red to purplish red; style and epicalyx elements often persistent. Seeds 11–12 mm in diameter, cream, often marbled. 中国植物志: 风轮桐属 Epiprinus Griff. 乔木或灌木;嫩枝被糠秕状的短星状毛。叶互生,常聚生于枝顶,羽状脉;叶柄长或短;托叶小。圆锥状花序,顶生或腋生,花雌雄同株,无花瓣,花盘缺;雄花多朵在苞腋排成团伞花序,稍密地排列在花序轴上,雌花数朵生于花序基部,花梗短,花序轴和苞片均被短星状毛;雄花:花萼花蕾时球形,萼裂片2-6枚,镊合状排列;雄蕊4-15枚,花丝离生,花药近基着,纵裂,药隔突出呈细尖;不育雌蕊小,呈倒圆锥状或柱状;雌花:萼片5-6枚,外向镊合状排列,花后增大或不增大;副萼鳞片状;子房3室,每室具胚珠1颗,花柱基部合生呈柱状,上部分离,平展,叉裂,具乳头状突起。蒴果具3个分果爿,近球形,具毛,内果皮厚,近木质;种子近球形,种皮壳质,具斑纹,胚乳肉质。 | |
