4 mm longis; corollae lobis late triangularibus, acuminatis, cir- 

 citer 6 mm longis, alte connatis, Indus dense papillosis, apice 

 leviter reflexis; coronae lobis coriaceis, oblongo-ovatis, 5 mm 

 longis, acuminatis vel acutis, patentibus, apice leviter retusis, 

 subplanis. 



A scandent shrub, entirely glabrous except the inflorescence, 

 the branches subterete, rather pale when dry, about 3 mm in dia- 

 meter, the intern odes up to 20 cm in length. Leaves opposite, 

 fleshy, when dry coriaceous, pale and shining on both surfaces 

 and more or less wrinkled, oblong to oblong-obovate, 10 to 14 cm 

 long, 3 to 5 cm wide, base obtuse, apex distinctly acuminate; 

 lateral nerves pinnately arranged, indistinct, about 6 on each 

 side of the midrib, ascending, scarcely more evident than are the 

 lax, indistinct reticulations; petioles about 1 cm long. Umbels 

 many-flowered, 8 to 9 cm in diameter, the thickened rachis about 

 4 mm in diameter above, the pedicels spreading, slender, about 

 3.5 cm long, sparingly appressed-pubescent. Flowers fragrant, 

 about 1.8 cm in diameter, brown when dry. Calyx-segments 

 oblong-ovate to ovate-lanceolate, acute or subacute, externally 

 somewhat pubescent, about 4 mm long. Corolla-lobes broadly 

 triangular, about 6 mm long and wide, spreading, rotate, exter- 

 nally glabrous, internally densely papillose, the acuminate apex 

 somewhat recurved. Corona 10 to 12 mm in diameter, stellate, 

 the lobes spreading, coriaceous, brown, shining, oblong-ovate to 

 ovate-lanceolate, acuminate, about 5 mm long, the external tip 

 slightly retuse, the internal one ascending, the upper surface 

 plano-convex and somewhat keeled in the median portion.

The alliance of this species is with Hoya luzonica Schltr., from which 

 it is readily distinguished by its larger flowers, its pubescent pedicels and 

 sepals, and its differently shaped, longer, acuminate, and slightly retuse 

 corona-segments.
