8. Physaliastrum Makino, Bot. Mag. (Tokyo). 28: 20. 1914.

散血丹属 san xue dan shu

Archiphysalis Kuang.

Shrubs or perennial or perhaps annual herbs; pubescence of simple hairs. Stems dichotomously branched. Leaves simple, petiolate. Inflorescences in branch forks, occasionally axillary, solitary or sometimes 2- or 3-flowered clusters; peduncle short or obsolete. Flowers mostly actinomorphic, 5-merous, long pedicellate, nodding. Calyx short campanulate or conical, lobed to halfway, lobes equal or not. Corolla broadly campanulate to rotate, lobed to halfway; lobes wide spreading, densely villous near base of tube, sometimes spotted. Nectaries sometimes present. Stamens inserted in corolla tube; filaments pubescent or glabrous; anthers dehiscing longitudinally. Disc rudimentary or absent. Ovary 2-locular; ovules numerous. Fruiting calyx becoming enlarged, applied to berry or inflated, mostly open at apex; veins obscure or thickened into angles or ribs, mostly muricate or bristly with soft emergences that appear deltate and scalelike when dry, these sometimes localized on angles. Fruit a juicy or fleshy berry enveloped in calyx. Seeds numerous, reniform-discoid, minutely pitted; embryo curved, subperipheral.

About nine species: Asia, seven species in China.

The genus Archiphysalis, which was recognized in FRPS, was placed into synonomy under Physaliastrum by D'Arcy & Zhang, Novon 2: 124-128. 1992. Many species were formerly known as Chamaesaracha A. Gray and Leucophysalis Rydberg, but these genera now include only New World taxa.

+ Fruiting calyx with unevenly thickened, winglike ribs, these with teeth or emergences that dry deltate   7 Physaliastrum chamaesarachoides
3 (1) Corolla with an evident nectary; fruiting calyx about as long as berry, apex open   5 Physaliastrum echinatum
