Bureau & K.Schum.FamíliaBignoniaceaeTipoNativa, endêmica do Brasil.DescriçãoYoung branchlets densely golden long-villous with trichomes over 1.5 mm long, scattered lepidote, without noticeable lenticels, interpetiolar ridges weak or absent; pseudostipules spatulate or ovate and basally attenuate, 3–20 3 2–15 mm. Leaves with tendrils trifid, or more frequently additionally branched, tips frequently disk-like; petiole 1–4.5 cm long, densely golden long-villous; petiolule 1–3 cm long, densely golden long-villous; leaflets ovate (rarely broadly oblong), 6–16 3 2.5–10.5 cm, membranous, veins palmate at base, with 4 to 7 pairs of secondary lateral veins, dense long-villous, pellucidlepidote, base subcordate to deeply cordate, apex acute and abruptly short-acuminate or short-caudate. Raceme 13–25 cm long with 10 to 20 flowers, peduncle, rachis, and pedicel densely golden longvillous, lepidote; bracteoles filiform, 3–10 mm long, caducous. Flowers with calyx 7–13 3 10–13 mm, densely tomentose to sericeous, lepidote; corolla densely sericeous above base, white or cream to yellow, 6.2–7 cm long, tube 4.5–5.8 cm long, length of thickened glabrous section 8–10 mm, width of tube at mouth 15–25 mm, glabrous internally except with a villous ring of trichomes at stamen insertion, the trichomes turgid and moniliform, lobes 10–16 3 10–17 mm; stamens and staminode inserted 5–10 mm from base of tube, longer filaments 27–35 mm long, shorter filaments 20–21 mm long, anthers ca. 4 mm long, staminode 6–10 mm long; disc 1.5–3 3 3.5– 6 mm; pistil 3.7–4.3 cm long, ovary broadly elliptic, ca. 6 3 4–4.2 mm, densely sericeous, stigma broadly rhombate or obovate. Mature capsule and seed not seen, immature capsule 11.5 3 3.5 cm, 0.7 cm in diam., base acute, apex acute, valve surface echinate, the spines ca. 2 3 2 mm, laterally flattened at base, the slender tips generally breaking off with age (POOL, 2007).CaracterísticaThis species is distinguished from the widespread and variable Pithecoctenium crucigerum primarily based on the very distinctive long golden trichomes that are found on most of the vegetative parts as well as the inflorescence peduncle, rachis, and pedicels. While vegetative and inflorescence pubescence is a very variable character in P. crucigerum, no trichomes havebeen seen in that species that approach the length of those in P. dolichoides (longer than 1.5 mm). The flowers of P. dolichoides also tend to be somewhat larger (corolla 6.2–7 cm) than those of P. crucigerum (3– 6.8 cm); however, there is a wide range in flower size in the latter and flower size ranges do overlap for the two species. It could be argued, as Sandwith and Hunt (1974) suggest, that P. dolichoides might be better treated as an infraspecies of P. crucigerum. Collection of the mature fruit and seed would help in determining the relationship of these two taxa (POOL, 2007).Floração / frutificaçãoDispersãoHabitatDistribuição geográficaOcorrências confirmadas: Sudeste (Rio de Janeiro, São Paulo); Sul (Paraná, Santa Catarina)Domínios Fitogeográficos: Mata AtlânticaTipo de Vegetação: Floresta de Terra Firme, Floresta Ombrófila (= Floresta Pluvial) (AMPHILOPHIUM, 2019).EtimologiaPropriedadesFitoquímicaFitoterapiaFitoeconomiaEventualmente cultivada como ornamental.InjúriaComentáriosBibliografiaAMPHILOPHIUM in Flora do Brasil 2020 em construção.
