直立亚灌木状草本，高1-2米；分枝多，小枝被柔毛至近无毛。叶披针形，长2-5厘米，宽4-10毫米，先端短尖或渐尖，基部圆或钝，具锯齿，两面均无毛或疏被星状柔毛，上面偶被单毛；叶柄长4-6毫米，疏被柔毛；托叶线形，与叶柄近等长，常宿存。花单朵或成对生于叶腋，花梗长4-12毫米，被柔毛，中部具节；萼浅杯状，无毛，长约6毫米，下半部合生，裂片.5，尾状渐尖；花黄色，直径8-10毫米，花瓣倒卵形，先端圆，基部狭长6-7毫米，被纤毛；雄蕊柱长约4毫米，疏被硬毛。蒴果近圆球形，分果爿4-9，但通常为5-6，长约3.5毫米，顶端具2短芒，果皮具网状皱纹。花期冬春季。
产台湾、福建、广东、广西和云南。常生于山坡灌丛间、路旁或荒坡。原产印度，分布 于越南和老挝。
其茎皮纤维供绳索料；根叶作药用，有抗菌消炎之功。
本种的叶披针形，两面无毛或被星状柔毛至偶具单毛，而胡秀英定的变种var. intermedia S. Y. Hu 称叶疏被星状柔毛而成立该变种，事实上有的标本出现具毛或无毛 的现象，因此该变种不能成立，予以归并。

直立分枝亚灌木状草本，高1—2米；小枝被柔毛或近于无毛。叶披针形，长2—5厘米，宽4—10毫米，先端短尖或渐尖，基部钝或圆形，具锯齿，两面均无毛或疏被星状柔毛，上面偶有单毛；叶柄长4－6毫米，被疏柔毛；托叶线形，长7—10毫米，常宿存。花单生或成对生于叶腋，花梗长4—12毫米，被柔毛，中部有节；花萼浅杯状，无毛，长约6毫米，下半部合生，萼裂5，尾状渐尖；花冠黄色，直径8—10毫米，花瓣倒卵形，先端圆，基部狭，长6－7毫米，被纤毛；雄蕊柱长4毫米，被疏硬毛，花丝细，花药黄色。蒴果近球形，分果爿4—9，但通常为5—6，长3.5毫米，端具短芒2，果皮具网状皱纹。花期冬春季。
云南的玉溪、文山、西双版纳、临沧、德宏等地州，海拔200—1400米的山坡灌丛或路旁、荒坡。分布于我国广东、广西、福建和台湾等省区。也分布至印度、越南及老挝。
本种茎皮富含纤维，供织绳索料；根叶入药有抗菌消炎作用。
本种的叶披针形，两面无毛至被星状柔毛或偶有单毛，因此胡秀英把有毛的定为变种（var. intermedia S. Y. Hu）应予归并。

黄花稔 huang hua ren

Malvastrum carpinifolium (Linnaeus f.) A. Gray; Sida acuta subsp. carpinifolia (Linnaeus f.) Borssum Waalkes; S. acuta var. carpinifolia (Linnaeus f.) K. Schumann; S. acuta var. intermedia S. Y. Hu; ?S. bodinieri Gandoger; S. carpinifolia Linnaeus f.; S. carpinifolia var. acuta (N. L. Burman) Kurz; ?S. chanetii Gandoger; S. lanceolata Retzius; S. scoparia Loureiro; S. stauntoniana Candolle.

Subshrubs or herbs erect, 1-2 m tall. Branchlets pilose or subglabrous. Leaves ± distichous; stipules filiform, 4-6 mm, often longer than petiole, usually persistent; petiole 4-6 mm, sparsely pilose; leaf blade ovate, oblong, lanceolate, or linear-lanceolate, 2-5 × 0.4-1 cm, both surfaces glabrous or sparsely stellate pilose, rarely with simple hairs adaxially, base obtuse, margin dentate, sometimes partly entire toward its base, apex acute or acuminate. Flowers solitary or paired, axillary, sometimes congested at stem apex. Pedicel 4-12 mm, pilose, articulate at middle. Calyx shallowly cup-shaped, connate in basal 1/2, ca. 6 mm, mostly glabrous, margins often ciliate, lobes 5, caudate. Corolla yellow, less often white or yellow-orange, 8-10 mm in diam.; petals obovate, 6-7 mm, ciliate, base attenuate, apex rounded. Filament tube ca. 4 mm, sparsely hirsute. Schizocarp nearly globose; mericarps (4-)6(-9), segmentiform-tetrahedral, ca. 3.5 mm, basally transversely ridged, side walls reticulate-veined, glabrous, apex beaked, ± extending into 2 awns, apically dehiscent. Seed trigonous, ca. 2 mm, glabrous except around hilum. Fl. winter-spring.

Scrub, roadsides, wastelands. Fujian, Guangdong, Guangxi, Hainan, Taiwan, Yunnan [Bhutan, Cambodia, India, Laos, Nepal, Thailand, Vietnam].

The glabrous calyx is usually diagnostic for Sida acuta. Sida bodinieri was described as glabrous and if correctly placed in Sida would most likely belong under S. acuta. Sida chanetii was related by the original author to S. acuta but it was based on a collection from near Beijing, well north of any other records for Sida, and so its identity needs confirmation.

The bark is a good fiber source, and the roots are used medicinally.
