 the ridges.

LYONSIA ALBIFLORA Gibbs, sp. nov. 



Fiiifex tenuis, volubilis, ramuli teretes, innovationes sparsim villosi, demuin 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-trichotoina, bracteis linearibus. 

 Flares 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, antherse basi sagittatae. 

 serai-exsertse, filauienta gracilia, piloso, non torta. Ovarium glabrum, disco o-lobo 

 circumdatum. 



Hob. Arfak Mts., twining in forest on S.W. ridge, 8000'; also in spinneys 

 by ? lake, 700(X. Fl. Dec. 5532. 



Leaves 5'5 cm. by 1 cm., 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 

 lateral veins, showing no reticulations on the under surface, the much longer 

 peduncles, and the pilose outer surface of the corolla.
