hairs. Pedicels 3-4 lines (6-9 mm.) long, pubescent with some- 

 what strigose hairs. Perianth segments 4 lines (9 mm.) long, 

 clothed on the outer surface with appressed strigose hairs. 

 Pistil glabrous ; ovary stipitate on a gynophore 1 J line (3 mm.). 

 Fruit not seen. 



Boku, British New Guinea, Mrs. H. P. Schlencker. 



This new species is quite unlike any other Papuan or .Australian 

 Grevillea known to me. The specimsns were collected by Mrs. Schlencker 

 in 1909 and referred by the late F. M. Bailey as near Finschia rufa 

 Warbg. It may, when the fruit is knowTi, prove a species of Finschia, 

 but it ciffers from F. rufa and F. chloroxantha, the only known members 

 of the genus.] 



Helicia validinervis sp. no v. 



Arbor, ramulis glabris ; foliis petiolatis lanceolatis sensim 

 longe acuminatis integris utrinque glabris reticulatis nervis 

 .subtus prominentibus ; racemis laxifloris rhachide pubescente ; 

 floribus geminatum pedicellatis pedicello dense pubescente ; 

 perianthii segmentis ferrugineo-pubescentibus ; ovario hirsuto, 

 stylo glabro. 



A tree, branchlets glabrous, finely striate. Leaves distinctly 

 petiolate, petiole i-1 in. (l'3"2-5 cm.) ; blade lanceolate, 

 tapering at the apex into a long acuminate point, 7-1 1| in. 

 (18-29 cm.) long, glabrous, green on both faces, strongly nerved, 

 main nerves jorominently raised on the under surface, reticula- 

 tions distinct between them, margins entire. Racemes shorter 

 than the leaves, about 7 in. (18 cm.) long, rhachis clothed 

 with rather long, scattered, ferruginous hairs. Flowers on 

 pedicels of about 1 line (2 mm.) ; pedicels and perianth seg- 

 ments ferruginous-pubescent, ovary densely clothed Avith long 

 villous hairs. 



Mekeo District. 



Among previously recorded Papuan species H. valid' nervis approaches 

 very closely to H. toricellensis Laut., which differs from it in its smaller 

 leaves insensibly tapering at the base into a petiole. From/?. Forbesiana 

 it differs in its larger flowers and smaller less p'-ominently veined leaves. 

 Lauterbach's key to the Papuan sp3cies of Helicia (Beitrage zur Flora 

 von Papuasien, iii, 330) places H. Forbesiana among tho.se with a 

 glabrous rhachis, whereas specinaBns from the National Herbarium, 

 Melbourne, and collected by Forbes, show the rhachis to be clothed with 

 scattered ferruginous hairs.
