LYONSIA ALBIFLORA Gibbs, sp. nov. 
Frutex tenuis, volubilis, ramuli teretes, innovationes sparsim villosi, demum glaber- 
rimi. Folia petiolata, oblongo-linearia, acuta, basi retundata vel subcordata, sensim 
acuminata, supra nitida, reticulato-rugosa. Inflorescentia unilateraliter axillaris, 
longe pedunculata, quam folia longior, divaricato-trichotoma, bracteis linearibus. 
Flores pedicellati. Calyx villosus, usque basin fere partitus, laciniis ovatis acutis. 
Corolla extus villosa, intus inter stamina et ad fauces barbata, laciniis latis lanceo- 
latis, strigosis. Stamina paullo infra basin tubo inserta, anthere basi sagittatie, 
semi-exsertw, filamenta gracilia, piloso, non torta. Ovariuwm glabrum, disco 5-lobo 
circumdatum. 
Hab, Arfak Mts., twining in forest on 8.W. ridge, 8000’; also in spinneys 
by ? lake, 7000’. Fl. Dec. 5532. 
Leaves 5°5 em. by 1 em., dull and smooth beneath, the young leaves 
yellowish with midrib impressed above and prominent beneath, with 4-5 
lateral veins all dark brown in colour. Petioles twisted, +7 mm. long. 
Inflorescence 5-7°5 cm. long. Flowers 7 mm. long. Pedicels pilose, 5 mm. 
long. Calyx-lobes 1 mm. long. Stamens 5 mm., anthers +6 mm. long, 
filaments arching over ovary, 2 mm. long. Ovary 1°5 mm, in length. 
Judging from Warburg’s description this plant is nearest to his L. diver- 
sifolia, but differs in the inconspicuous venation of the leaves with fewer 
jateral veins, showing no reticulations on the under surface, the much longer 
peduncles, and the pilose outer surface of the corolla.
