(Plates xxxiv.-xxxv.) 



Parsonsia Paddisoni, n.sp. 



A glabrous woody climber. Leaves opposite, on a petiole from 

 6 to 8 lines long, obovate, elliptical-lanceolate, abruptly acuminate, 



glabrous on both sides, upper 

 surface dark green, venation 

 about equally prominent on both 

 sides, reticulations perhaps more 

 distinct on the upper surface, 

 under side pale-coloured, mar- 

 gins recurved, about 3 to 4 inches 

 long. 



Cymes axillaxy, only in one 

 axil of the pair of leaves, ped- 

 uncles pubescent, shorter than 

 the leaves. Calyx-segments 

 equal, lanceolate, subulate, rib- 

 bed, pubescent, 1 to 1 1 lines long, 

 margins hyaline. Corolla-tube 

 shorter than the calyx, con- 

 stricted at the attachment of the 

 stamens, lobes glabrous, about 2 

 lines long, the right edge imbri- 

 cate. Filaments slender, pubes- 

 cent, slightly twisted under the 

 anthers ; anthers wholly ex- 

 serted, acuminate, forming a 



cylinder nearly as long as the corolla, without dorsal appendages, 



basal lobes long, incurved at the ends.
