~_ Discovered by Dr. Blume in mountain woods on the western 
side of Java. Mr. Thomas Lobb detected it in the same island, 
_ on Mount Salak, and transmitted living plants to the rich 
nursery of Messrs. Veitch at Exeter, in whose collection this 
handsome species first blossomed in August 1849. It is a 
climber, and requires the heat of the stove. 
Descr. Everywhere glabrous. Stem branched, twining, terete ; 
young branches green. Leaves opposite, on short thick petioles, 
which are glandular above at the setting on of the blade, which 
latter is almost exactly elliptical, or approaching to ovate, acute, 
between coriaceous and fleshy, acute or shortly acuminated, 
costate, penniveined, the veins rather indistinct. Pedwncles sub- 
axillary, solitary, terete, longer than the leaf, pendent, bearing 
a large wmbel of numerous flowers, brown in the state of the 
bud, much paler when fully expanded. Pedicels very obscurely 
villous. Calycine segments subulate, much shorter than the 
corolla. Corolla rather large, glabrous and glossy externally, 
within pale tawny and downy: the lobes triangular, acute, 
the sides a little reflexed. Staminal crown white, with a dark 
brown eye ; leaflets ovate, gibbous at the base, obtuse, the apex 
a little curved down. W. J. H.
