形态特征

小乔木或灌木,3-4米(? 或更多)高,显然无刺; 小枝多少具锈色短柔毛,毛开展,相当长。叶柄5-10毫米,略粗,密被有毛,毛开展,带褐色,直,长(0.5-1毫米);

叶片卵形到卵状椭圆形, 11-18 * 4.5-7.5厘米,厚纸质,背面整个具的软的短柔毛, 触摸时柔软, 毛开展和长(0.5-1毫米), 除近的叶柄顶之外的正面无毛,中脉在上面凹陷;

侧脉4-6 对,突出,基部宽锐尖到圆形,边缘浅锯齿到细锯齿,全缘至基部,先端钝,收缩至狭渐尖头1-2厘米,最顶端钝。多数花序腋生,总状具轴约1厘米,或退化为团伞花序或束簇;

轴浓密有毛,出现近具刚毛在10倍下,毛开展,长约0.5毫米; 苞片卵形到披针形,1-2毫米,两面稀疏具刚毛。 花梗长约1毫米在雌花,在雄花(很少标本可见)的长约3毫米,具刚毛。

萼片4-6,卵形,1-1.5毫米,大小不等,两面和边缘疏生具刚毛,或正面近无毛,先端锐尖。雄花 雄蕊花丝3-4毫米,无毛。 雌花 瓶形的子房,1.5-2毫米,无毛;

花柱合生为短柱状的长约0.5毫米; 柱头4-6,辐射状,,扁平肾形。 干果长圆形多边形到倒卵球形多边形,约1厘米(?未发育完全),具纵向的角。

Small trees or shrubs, 3-4 m (?or more) tall, apparently unarmed; branchlets ± rusty pubescent, hairs spreading, rather long.

Petiole 5-10 mm, stoutish, densely hairy, hairs spreading, brownish, straight, long (0.5-1 mm); leaf blade ovate to ovate-elliptic, 11-18 × 4.5-7.5 cm, thickly papery, abaxially softly pubescent throughout, soft to the touch, hairs spreading and long (0.5-1 mm), adaxially glabrous except near petiole apex, midvein impressed above, lateral veins 4-6 pairs, prominent abaxially, base broadly acute to rounded, margin shallowly serrate to serrulate, entire toward base, apex obtuse, contracting to a narrow acumen 1-2 cm, extreme tip obtuse.

Inflorescences mostly axillary, racemose with axis ca. 1 cm, or reduced to glomerules or fascicles; rachises densely hairy, appearing nearly bristly at × 10 mag., hairs spreading, ca. 0.5 mm; bracts ovate to lanceolate, 1-2 mm, both surfaces sparsely bristly.

Pedicels ca. 1 mm in pistillate flowers, ca. 3 mm in staminate flowers (few specimens seen), bristly. Sepals 4-6, ovate, 1-1.5 mm, unequal in size, both sides and margin sparsely bristly, or adaxially nearly glabrous, apex acute.

Staminate flowers: stamen filaments 3-4 mm, glabrous. Pistillate flowers: ovary bottle-shaped, 1.5-2 mm, glabrous; styles connate into a short column ca. 0.5 mm; stigmas 4-6, radiating, recurved, flattened-reniform. Dried fruit oblong-polygonal to obovoid-polygonal, to ca. 1 cm (?immature), longitudinally angled.

产地生境

Mountain forests; 1000-1700 m. Yunnan [Myanmar]. 山地森林;1000-1700米。云南 [缅甸 ]。

辨析

Flacourtia mollis is sometimes misidentified as the Indian en- demic F. montana J. Graham. The two species can be distinguished by the abaxial indumentum of the leaf: in F. mollis , it is softly hairy throughout; in F. montana, it is sparsely hairy only along the midvein and lateral veins. Gatherings of F. mollis seem scarce; more material is required to confirm and improve the above description.

Flacourtia mollis有时被错误鉴定为印度的本地种F. montana J. Graham.。两种可以按叶的背面的毛被区分: F. mollis,它全部具软毛;F. montana,只沿着中脉和侧脉是疏生有毛。F. mollis的采集好像不足;更多的材料被要求确认并且改进上述描述。
