blade readily deciduous, reflexed, triangular-linear or linear-lanceolate, adaxially slightly pilose, one margin dentate-serrulate.

Leaf blade broadly elliptic, similar to pear leaves, margin serrulate or serrate; pyrenees oblong, endocarp stony.

Sepals triangular-ovate, soon caducous, outside glabrous, margin serrulate, apex acute.

blade linear-lanceolate, scabrous, margins sparsely serrulate.

leaflet blade base usually oblique, margin usually entire, very rarely serrulate.

lobes ovate or oblong, basal lobes smaller, margin serrulate, apex acute to caudate-acuminate.

Leaf blade abaxially nearly glabrous, base truncate, margin serrulate. Inflorescence dense.

Leaves alternate; stipules absent; leaf blade margin serrate or serrulate.

Leaf margin serrulate, leaf blade scabrous; capsule spines branched, soft.

leaf blade leathery to papery, glabrous, margin serrulate to serrate or denticulate.

Leaf margin usually 10- or more lobed, lobe margin doubly serrulate; inflorescences with many long branches.

blade reflexed at culm base, linear, slightly hairy, margins serrulate.

Native species; pome small, with long pedicel, leaf blade serrulate; branchlets, buds, and leaves with few hairs.

Leaf blade elliptic to oblong-elliptic, margin distinctly triangular-serrulate; corolla tube ca. 4 mm.

the serrulate margin of leaves developed from the epidermis' cell wall.

Leaves elliptic or elliptic-lanceolate, apex caudate; bracteoles spiny, 2-parted at base; pseudostaminode serrulate at apex.

blade reflexed, linear-lanceolate or linear, basally slightly hairy adaxially, margins serrulate.

Capsule subglobose, prickly; leaflets abaxially green, margin serrate with teeth serrulate.

2 (1) Leaf blade oblong-elliptic, secondary veins visible on both surfaces, margin densely apiculate-serrulate.

Leaf blade margin sharply serrulate, crenate, or subentire.

Branchlets purple-black; leaf blade papery, margin sparsely and shallowly serrulate.

Petiole sparsely prickly or unarmed; leaves papery to membranous, margins serrulate-ciliate, with 4-6 teeth per cm.

Herbs. Leaves entire or serrulate.

8 (7) Leaf blade margin serrulate, leaf blade elliptic to obovate-elliptic or suborbicular.

Bract margin entire or densely and minutely serrulate to fimbriate; pedicels spreading or slightly ascending, 1--3. 5 cm, slender.

Leaves 3- or 5-lobed, sometimes undivided, margins remotely dentate to serrulate.

This is a common species that can be easily identified by its sharp and double-serrulate leaf margin.

Leaf blade margin densely apiculately serrulate; bracteoles and sepals 8-10, caducous after anthesis.

13 (12) Lateral lobes apically shortly obtuse or obsolete, rarely acute, margin closely serrulate.

Petiole ca. 1 cm; leaf blade oblong, leathery; sepals ovate, 7-8 mm, margin serrulate, outside velutinous.

Petiole densely prickly, leaves subleathery, margins spinose-serrulate, with 2-3 teeth per cm.

leaf blade cordate-ovate, veins 7-9, basally palmate, margin sparsely serrulate.

Stipules ca. 2 mm; leaf margin incised-serrulate; achene ca. 1 mm.

bracts subulate, 1-1. 5 mm, glabrous, red punctate, margin roughly serrulate.

Petiolules 0-5 mm, pubescent; leaflets with 7-10 primary veins on each side of midrib, margin entire or serrulate in upper part.

Calyx to 1. 3 cm, lobes distinctly serrulate.

leaf blade ovate, usually hairy abaxially, basal veins 5-7, margin entire or serrulate, apex acute, sometimes 3-5-lobed.

petiole short; leaf blade margin entire or crenate-serrulate;

leaf blade thinly papery or papery, 3-veined, often snow white or silvery tomentose abaxially, margin serrulate;

calyx cup-shaped, 3-lobed, lobes irregularly serrulate;

calyx cup-shaped, 3-lobed, lobes broadly ovate, serrulate;

Sepals 4, rarely 5, lateral ones smaller, nephroid-semiorbicular, margin irregularly serrulate;

sepals 6, 2-seriate, ovate-lanceolate, ca. 6 mm, apex with awn-shaped acumen, margin irregularly serrulate;

calyx 3-lobed, lobes broadly ovate, ca. 1 mm, margins serrulate;
