 1. WILLOUGHBEIA, Roxb. 



Glabrous shrubs, often climbing by the peduncles becoming tendrils. Leaves 

 opposite, petiole short. Floivers in axillary cymes. Calyx short, 5-lobed. 

 Corolla, salver-shaped, tube nearly glabrous within, mouth naked or with fleshy 

 glands alternating with, the lobes ; lobes overlapping to the left, nearly straight 

 in bud. Stamens included in the tube, and filaments very short ; anthers ovate or 

 lanceolate, cells rounded at the base. Disc 0. Ovary 1-celled ; style short, top 

 obconic or urceolate, stigma curved or columnar ; ovules many, oo -seriate on 2 

 parietal placentas. Berry large, globose or ovoid, many-seeded, pericarp hard. 

 Seeds imbedded in pulp, ellipsoid, albumen ; cotyledon thick, plano-convex. 

 DISTRIB. Species 8-10, Malayan and East Asiatic. All supposed to yield 

 Caoutchouc. 



The species -with glands on the corolla-mouth may form a different genus. I have 

 seen no tendrils on these. 



* Mouth of corolla naked.
