Petiole nearly as long as leaf blade; leaf blade broadly elliptic, ovate, or suborbicular, 0.5-1.5 × 0.4-0.9 cm, stellate hairy, base cuneate-attenuate, margin entire, apex rounded, mucronulate; midvein obscure.

Leaves alternate; petiole 1.5-2.5 mm, densely white tomentose; leaf blade adaxially light green, elliptic, lanceolate, or ovate-oblong, small, narrow, 1-2 cm × 5-8 mm, stiffly papery, abaxially densely and persistently gray-white tomentose, adaxially glabrous or sparsely white pubescent, lateral veins 4-6 pairs, midvein prominent abaxially, inconspicuous adaxially, base obtuse, margin serrulate, apex obtuse or acute, rarely rounded, often long mucronulate. Flowers yellow-green, sessile, gray-white pubescent, usually in terminal and axillary spicate panicles; rachis 1-2 cm, densely gray-white pubescent.

叶互生 叶柄1.5-2.5毫米，密被白色；叶片正面淡绿，椭圆形，披针形，或卵状长圆形的，小，狭窄，1-2厘米*5-8毫米，硬纸质，浓密背面和持续灰白色被绒毛，正面无毛或者稀少白色短柔毛，侧脉4-6对，花黄色绿色，无梗，灰白色短柔毛，通常在顶生和腋生穗状圆锥花序里；轴1-2厘米，浓密灰白色短柔毛。

Calli were induced at a high frequency of 76.4±3.2% from petiole explants excised from two-month-old plants on Murashige and Skoog medium supplemented with 5.37 μMα-naphthaleneacetic acid and 4.44 μM 6-benzyladenine.

采用2个月苗龄植株的幼叶柄为外植体，接种於附加5.37μMNAA和4.44μMBAMS培养基，愈伤组织诱导频率高达76.4±3.2%。

No callus could be induced from leaf or petiole explants of varieties F30 and Ⅱ cultured on MS medium if supplemented alone with 6-bezyladenine （6-BA） or thidiazuron, or kinetin. However, the calli were induced on MS medium containing 2.0 mg L-1 6-BA and 0.5 mg L-1 NAA （α-naphthaleneacetic acid）, and the calli derived from petioles of variety Ⅱ could produce redifferentiated shoots, but of variety F30 could not. The later could only produce shoots directly from the base of the petioles.

将品种F30和Ⅱ的叶片和带叶叶柄接种到含不同浓度单一细胞分裂素（6-BA、TDZ、KT）的MS培养基上培养，均未能诱导出愈伤组织，而在含2.0mgL-1 6-BA＋0.5mgL-1 NAA的培养基上可以诱导出愈伤组织，且由品种Ⅱ叶柄诱导产生的愈伤组织可再分化出芽，品种F30诱导的愈伤组织却不能分化，但在其叶柄基部可直接出芽。

Rhizome long and thin or shortly nodulose; leaf blade ternate, petiole narrow; involucral bracts petiolate; pistils and achenes with distinct style and small, usually linear stigma.

短的根状茎长和薄的或具小节；三出的叶片，狭窄的叶柄；总苞片具叶柄；雌蕊和瘦果具离生的花柱和小，通常线形柱头。

Branches spreading; leaf blade narrowly elliptic, ovate, or obovate; petiole 5–10 mm.

分枝平展；叶片狭椭圆形，卵形，或倒卵形；叶柄5-10毫米 3 R。

Leaves radical, tufted; peti- ole slender,(2–)4–9(–11) cm; leaf blade orbiculate, orbiculate-elliptic, or ovate, variable even on same plant,(0.5–)1.5–5 ×(0.3–)1.5–5.5 cm, thinly leathery, abaxially pale green, adaxially dark green, base truncate, subcordate, or attenuate and shortly decurrent into petiole, margin apiculately obtuse-serrate, rarely subentire, and often undulate, apex rounded to truncate and sometimes minutely retuse; secondary veins 3 or 4 on each side of midvein.

叶胚根，丛生； peti纤细的ole，(2-)4-9(-11)厘米；叶片圆形，圆形的椭圆形，或卵形，即使在相同的植株上也易变，( 0.5-)1.5-5 *(0.3-)1.5-5.5 厘米，薄革质，背面的苍绿色，正面深绿色，基础截形，近心形，或渐狭和短下延成叶柄，次脉在中脉两边各3或4。

Leaves opposite, simple, lobed, or palmately 3-foliolate; petiole long.

叶对生，单，浅裂，或具3小叶；叶柄长。

Leaves (3-)5(-9)-palmatifid, lobes entire; petiole with 2-4(-6) glands; stipules large, reniform, clasping.
