小乔木，高达8-10米；小枝无毛，具纵条纹。叶薄革质，阔卵形或宽椭圆形，长10-20厘米，宽5-12厘米，先端急尖或渐尖，基部圆钝，边缘具腺锯齿，两面无毛；侧脉7-10对，中脉在上面下陷，中脉和侧脉在下面明显突起，脉细而平行，与网脉在下面稍突起；叶柄粗壮，长1-2.5厘米，无毛。总状花序腋生，通常2-3个簇生，稀单生，直立，长10-15（20）厘米；花序轴及花梗被短柔毛，稀近无毛；花梗长1.5-2毫米，苞片钻形；萼筒杯状；萼片三角状披针形，长1.5毫米，被微毛；花瓣白色，狭披针形，长3-4毫米，稍尖，花时常反折；雄蕊短于花瓣之半；花丝无毛；花药长圆形，背向着生；子房半下位，无毛；2心皮，紧贴；柱头头状。蒴果狭锥形，长7-8毫米，无毛，具纵条纹，平展或下垂。花果期4-6月。
产海南（澄迈、儋县、崖县、白沙、保亭、乐东、昌江、感恩及东方等）、广西（武鸣）、云南南部（澜沧、耿马、西双版纳、思茅、沦源、盈江、勐海、绿春、红河、景谷、陇川、孟连等）。常见于海拔500-1540米的疏、密林中或山坡路边。印度、锡金、不丹、缅甸、越南、菲律宾及印度尼西亚（爪哇）也有分布。模式标本采自印度东部。
茎皮多纤维可供制绳及麻袋、造纸用。

Itea maesifolia Elmer; I. luzonensis Elmer; I. puberula Craib; Kurrimia macrophylla (Wallich) Wallich ex Meisner.
Trees 8-10 m tall. Branchlets striate, glabrous. Petiole stout, 1-2.5 cm, glabrous; leaf blade elliptic or broadly ovate, 10-20 × 5-12 cm, thinly leathery, both surfaces glabrous, midvein and secondary veins distinctly raised abaxially, midvein impressed adaxially, secondary veins in 7-10 pairs, tertiary veins parallel, fine, reticulate veins slightly prominent abaxially, base rounded-obtuse, margin glandular serrate, apex acute or acuminate. Racemes axillary, usually 2- or 3-clustered, rarely solitary, erect, 10-15(-20) cm; bracts subulate. Calyx cupular; lobes triangular-lanceolate, ca. 1.5 mm, puberulous. Petals reflexed at anthesis, white, narrowly lanceolate, 3-4 mm, apex subacute. Stamens ca. 1/2 as long as petals; filaments glabrous; anthers dorsifixed, oblong. Ovary semi-inferior, glabrous. Stigma capitate. Capsule spreading or pendulous, striate, narrowly conical, 7-8 mm, glabrous. Fl. and fr. Apr-Jun. 2n = 22.
