carpels and in its symmetrical leaves. Its alliances otherwise are 
manifestly with Polyalthia § Monoon, from which it is at once 
distinguishable by its united petals. Like Papualthia it is probably 
a derivative of Polyalthia. Its flowers somewhat resemble those 
of Enicosanthum, but structurally are very different from those of 
that genus, and ‘the proposed new genus is certainly not closely 
allied to Enicosanthum. 
MYRISTICACEAE. 
Knema Loureiro 
Knema winkleri sp. nov. 
Arbor, inflorescentiis exceptis glabra, ramulis ferrugineis, 
alaberrimis; fohis oblongis vel oblongo-ellipticis, coriaceis, 11- 
14 cm. longis, utrinque acutis, supra nitidis, olivaceis, subtus 
glaucis, nervis utrinque circiter 11, distinctis; floribus ¢ in ala- 
bastris depresso-globosis, subtriangularibusque, ferruginec-puses- 
centibus, circiter 2.5 mm. diametro; “pedicellis circiter 4 mm. longis ; 
disco stamineo brevissime stipitato, glabro, triangulare 1.5 mm. 
diametro ; antheris 6, in paribus ad angulos dispositis. 
A tree entirely glabrous except the inflorescences. Branches 
dark-brown, terete, somewhat rugose, the bark fissured when dry, 
the very young branchlets ferruginous, shining, not at all pubes- 
cent. Leaves o blong to oblong elliptic, coriaceous, 11 to 14 cm. 
long, 4.5 to 5.5 em. wide, slightly subequally narrowed to the acute 
base and apex, the upper surface olivaceous, shining, the lower 
surface glaucous, the midrib and lateral nerves distinct on both 
surfaces, very prominent beneath, the nerves about 11 on each side 
of the midrib, the reticulations evident on both surfaces; petioles 
about 1.5 em. long. Staminate flowers fascicled in the leaf axils 
-and in the axils of fallen leaves, 5 to 10 in a fascicle, the pedicels 
minutely ferruginous-pubescent, about + mm. long, with a very 
small bracteole at the upper one-fourth, the buds minutely ferru- 
ginous-pubescent, depressed-ylobose, distinctly triangular, about 
2.5 mm. in diameter; perianth-lobes coriaceous, orbicular-ovate, 
about 3 mm. long. Staminal disk subsessile, triangular, about 1.5 
mm. in diameter, the anthers 6, in pairs, a pair at each angle ot 
the disk. 
Dutch Borneo, Hayoep, Winkler 2390, 1908. A remarkably 
distinct species. The specimens have been distributed as Litsea 
sp. It apparently is most closely allied to Anema wrayt Warb. of 
the Malay Peninsula, from which it is distinguished by its flowers, 
nerves, and especially by its distinctly triangular buds, strongly 
triangular staminal disk, and by its few anthers, these being 6 only 
and in pairs at the angles of the disk, the sides of the disk being 
naked and without anthers.
