Arbustos hasta 10 m, escandentes, epifíticos o terrestres; tallos maduros teretes a subteretes, estriados, glabrescentes; ramitas teretes a obtusamente anguladas, estriadas, pubérulas. Hojas 4-10 × 1.5- 3.5 cm, alternas, elípticas a ovado-elípticas, pubérulas proximalmente a lo largo del nervio medio en el haz, glabras en otras partes, la nervadura 3-5(-7)-plinervia desde cerca de la base, el nervio medio y nervaduras laterales impresos en el haz y prominentemente elevados en el envés, los nérvulos reticulados planos a impresos en el haz y elevados en el envés, la base cuneada y obtusa o redondeada a subcordata, los márgenes enteros y ligeramente revolutos, el ápice acuminado; pecíolos 3-5 mm, subteretes, aplanados adaxialmente, puberulentos. Inflorescencias generalmente con 2-10 flores, delgadas y delicadas en apariencia; raquis 1.2-4 cm, subterete a obtusamente angulado, glabro pero esparcidamente fimbriado-glandular; brácteas florales c. 3 mm, oblongo-lanceoladas, largamente acuminadas, glabras pero marginalmente fimbriado-glandulares; pedicelos 10-15 mm, subteretes, estriados, glabros pero esparcidamente fimbriado-glandulares; bractéolas c. 2 mm, similares a las brácteas florales. Flores con el cáliz 8-10 mm, glabro, esparcidamente fimbriado-glandular, el tubo 5-6 mm obprismático, las alas 2-2.5 mm, conspicuamente nervadas, el limbo 5-6 mm, subpatente, los lobos c. 2 mm, triangular-ovados, afiladamente agudos, conspicuamente nervados, los senos obtusos; corola 10-13 × 10-12 mm en el punto más amplio, conspicuamente contraída en la garganta, ligeramente obovado-urceolada con las alas más amplias por encima de la mitad, las alas 2-5 mm de ancho, semi-ovadas, con fimbrias glandulares esparcidas, anaranjada a anaranjado-rojiza hasta la garganta donde se torna verde, los lobos 1-2 mm, ovados, obtusos, blancos; estambres 7-10 mm, más cortos que la corola; filamentos c. 4 mm, esencialmente distintos pero ligeramente connatos como por la 1/2 de su longitud, ligeramente sigmoides, con pelos glandulares claviformes, dorsalmente hacia los ápices; anteras 4-6 mm, las tecas 2-3.5 mm, mucronadas en la base, los túbulos 2-3 mm, casi del largo de las tecas, dehiscentes por hendiduras introrsas de casi la 1/2 o más de la longitud de los túbulos.

shrub or low tree

ranges along the Pacific slope of the Western Cordillera of the Andes from eastern Panama (Darien) into Ecuador.

Epiphytic shrub or low tree; mature branches terete, glabrate; immature branches and twigs of new growth terete, puberulous, tan when dry. Leaves oblong or ovate oblong to lance elliptic, 6-13 cm long, 2.5-6 cm wide, basally subcordate, bluntly acuminate, puberulous proximally along the midrib above, glabrous elsewhere, entire, the margin slightly revolute, 5-7-plinerved, the sec- ondary veins originating near the base and the midvein flush or slightly impressed above, prominently elevated beneath, the veinlets copiously reticulate and slightly raised on both the surfaces; petioles subterete, flattened above, puberulent, 3-5 mm long, 1.5-2 mm in diameter. Inflorescence axillary, short racemose with usually ca. 4 flowers; rachis subterete basally, 1-2 cm long, basally surrounded by several triangular to oblong bracts 3-5 mm long; pedicels subterete basally but becoming winged distally, striate, glabrous, 1O-20 mm long, each subtended by an oblong bract 3-6 mm long with scattered glandular fimbriae; bracteoles lacking. Flowers glabrous; hypanthium urceolate to obprismatic, ca. 8-9 mm long, the wings ca. 1-1.5 mm wide, the limb subspreading, 8-9 mm long including the lobes; calyx lobes triangular ovate, acute, 5-7 mm long, 4-5 mm wide at the base, ca. 7 parallel, branching veins not quite extending to the margin; corolla white, membranous when dry, 10-14 mm long, ca. 16 mm in diameter at the wid- est point, slightly contracted at both the base and apex and with semiobovate wings 2-5 mm wide, a single longitudinal vein parallel to the margin, the lobes ovate, apiculate, ca. 1 mm wide; stamens 8-10 mm long, the filaments ca. 4 mm long, membranous, connate for about 1/2 their length, adnate to the corolla; anther sacs ca. 2 mm long, gradually tapering into flexible tubules ca. 3 mm long and opening by introrse clefts about ?/- the length of the tubule; stigma truncate. above, prominently elevated beneath, the veinlets copiously reticulate and slightly raised on both the surfaces; petioles subterete, flattened above, puberulent, 3-5 mm long, 1.5-2 mm in diameter. Inflorescence axillary, short racemose with usually ca. 4 flowers; rachis subterete basally, 1-2 cm long, basally surrounded by several triangular to oblong bracts 3-5 mm long; pedicels subterete basally but becoming winged distally, striate, glabrous, 1O-20 mm long, each subtended by an oblong bract 3-6 mm long with scattered glandular fimbriae; bracteoles lacking. Flowers glabrous; hypanthium urceolate to obprismatic, ca. 8-9 mm long, the wings ca. 1-1.5 mm wide, the limb subspreading, 8-9 mm long including the lobes; calyx lobes triangular ovate, acute, 5-7 mm long, 4-5 mm wide at the base, ca. 7 parallel, branching veins not quite extending to the margin; corolla white, membranous when dry, 10-14 mm long, ca. 16 mm in diameter at the wid- est point, slightly contracted at both the base and apex and with semiobovate wings 2-5 mm wide, a single longitudinal vein parallel to the margin, the lobes ovate, apiculate, ca. 1 mm wide; stamens 8-10 mm long, the filaments ca. 4 mm long, membranous, connate for about 1/2 their length, adnate to the corolla; anther sacs ca. 2 mm long, gradually tapering into flexible tubules ca. 3 mm long and opening by introrse clefts about ?/- the length of the tubule; stigma truncate.
