Talipariti Fryxell

Descripción
Trees (rarely shrubs) 3-50 m tall, the trunks erect or spreading, sometimes angularly branched, the twigs minutely lepidote, puberulent, stellate-pubescent, or with long simple hairs, often glabrescent. Leaf blades often coriaceous, sometimes discolorous, ovate (rarely elliptic or obovate, sometimes deeply lobed in 7. hastatum), basally rounded to deeply cordate (rarely cuneate), apically acute or short-acuminate, the margins usually entire (or sometimes obscurely crenulate or denticulate), palmately (or sometimes pedately) nerved, sometimes with one or more nectaries on the abaxial side of the nerves (nectaries usually solitary near base of blade or less commonly several, more distally placed, sometimes absent); petioles usually shorter than (rarely subequal to) the blade, with pubescence similar to that of the young branches although sometimes denser: stipules prominent, lance-ovate to oblong (rarely subfalcate or suborbicular), from 0.5—3 cm long to as much as 11 cm long in T. macrophyllum, sessile and amplexicaul at shoot apex (appressed to stem and enclosing the terminal bud), variously pubescent to glabrescent, rarely spreading or somewhat reflexed, usually early deciduous, leaving prominent annular scars. Pedicels solitary in the upper leaf axils, usually stout and relatively short (rarely exceeding the petioles, except much longer than the petioles in T. glabrum and T. schlechteri), sometimes aggregated terminally or on short side-branches in few-flowered (or up to 9-flowered in T. potteri) sympodial inflorescences; involucel cither gamophyllous and cupuliform with 8-12 (or more) dentate or lanceolate teeth or of 5-10 distinct elements, each ligulate to lanceolate to cordate-ovate; calyx 5-lobed (ca. half-divided or sometimes deeply divided), the lobes often costate, more or less plicate in bud distally, with or without a nectary on the midrib of each lobe; corolla campanulate (reflexed in T. borneense), usually large and showy, yellow (with or without a purplish center), white, rose-pink, red, or purplish (sometimes changing color on falling, e.g. yellow to orange or red); staminal column included within corolla, basally pubescent (sometimes densely lanate forming a cushion) or glabrous, antheriferous distally or throughout length, apically 5-dentate; styles emergent from the staminal column, distally distinct, sometimes pubescent, the 5 stigmas capitate or obliquely capitate, sometimes purplish. Capsules subglobose or ovoid (rarely obovoid), externally densely pubescent (the hairs often yellowish, lepidote, stellate, or simple, sometimes in combination), internally glabrous or sometimes densely wooly, 5-locular but sometimes apparently 10-locular as a result of the presence of false papery dissepiments; seeds 2 to many per carpel, reniform, 3-5 mm long, densely pubescent to seemingly glabrous (though minutely papillate or scabridulous).A
Discusión taxonómica
The species of Talipariti seem to be flowering and fruiting in all months of the year, although data is scant for several species. Only for T. hamabo and perhaps for T. ellipticifolium is a clear seasonal pattern evident.
A key for Talipariti species can be found on Fryxell (2001).
