of the genus than either of the above. It does not appear to be closely 
allied to any previously described Philippine form. 
ELAEOCARPUS MONOCERA Cav. Ic. 6 (1801) 1, t. 501. 
Elaeocarpus megacarpa Elm. Leaf!. Philip. Bot. 7 (1915) 2627. 
This species, a very characteristic one, is widely distributed in the Phil- 
ippines. The type material, on which Cavanilles’s description and figure 
were based was from Los Banos and Jala-jala, Luzon, points on opposite 
sides of Lake Bay. I can see absolutely no reason for distinguishing 
Elaeocarpus megacarpa Elm. from E. monocera Cav. The species is rep- 
resented by the following specimens: 
Luzon, Cagayan Province, Aparri, For. Bur. 23687 Bernardo, locally 
known to the Negritos as tabian; For. Bur. 17916 Bernardo, locally known 
to the liocanos as panulauen (specimen erroneously localized as from Isa- 
bela Province on the herbarium label) : Rizal Province, Phil. PI. 1051

An erect, somewhat branched perennial herb from a much 
thickened underground base, the branches up to 60 cm in length, 
these, the branchlets, leaves and bracts prominently hispid-

and rather coarsely toothed, scabrid, somewhat hispid-hirsute 
on both surfaces ; petioles 2 to 6 cm long. Flowers yellow, with
