Shrubs [trees] or vines. Stems ± erect; twigs multicellular stipitate-glandular-hairy and, sometimes, conspicuously strigose (hairs elongate, stiff, long-celled, eglandular), otherwise sparsely to densely unicellular-hairy. Leaves persistent or deciduous, alternate, sometimes pseudoverticillate [in whorls of 3]; blade ovate, elliptic, or slightly obovate, coriaceous, margins obscurely to clearly toothed or serrulate [entire], plane or revolute, surfaces multicellular, short-stalked stipitate-glandular-hairy (along with, in P. floribunda, stout, elongate hairs associated with marginal teeth, and unicellular-hairy on midvein adaxially); venation brochidodromous to reticulodromous (veins of varied thickness and conspicuousness). Inflorescences axillary or terminal panicles or racemes, 15–35-flowered, (borne the year preceding flowering). Pedicels: bracteoles 2, proximal or distal. Flowers: sepals 5, slightly connate, ovate [oblong-lanceolate]; petals 5, connate for nearly their entire lengths, white, corolla urceolate to cylindric-urceolate, lobes short; stamens 10, included; filaments straight or geniculate, glabrous or hairy, with 2 stout, minutely papillose spurs at anther-filament junction; anthers without awns, dehiscent by elliptic pores; pistil 5-carpellate; ovary 5-locular; stigma capitate. Fruits capsular, subglobose or globose to ovoid, (with unthickened sutures), dry. Seeds 40–100, ellipsoidal to obovoid, ± rectangular or angular-ovoid, or narrowly conic, flattened or not, (sometimes slightly winged); testa cells elongate or isodiametric. x = 12.
