This is one of the species on the borders of I'asania and Cyclobalanus ; for the seal-- 

 although not united by their edges so as to form lamellsB, are in v rticels which resemble 

 lamellae; and between actual lamella? with denticulate edges, and v> rtieels of scales 

 closely touching by their edges and with their apices manifestly free, it is indeed 

 difficult to draw a line. Miquel, in his original description, did not indicate whether he 

 considered this to be a Pasania or a Cyclobalanus. M. I)e Candollo puts it in the latt i 

 but specimens in the Herbaria at Leiden, Kew, and Calcutta, named by MiqueFi own 

 hand, have the cupules more like those of a Pasania, and in leaves as well as fruit they 

 exactly resemble Scheffer's type specimens of his Q. brevi-petiolata, which he referred to 

 Pasania. On the other hand, specimens collected by myself from a tree in Singapore 

 have cupules so lamellate that I for some time considered them to belong to Q. Ewyckii, 

 a Cyclobalanus which much resembles this species in leaves. 



It is not at all clear to me that this species should not be merged in Q. pseudo- 

 Molucca, Bl. The only authentic materials of the latter have indeed more coriat ous 

 leaves and larger fruit; but the material is so poor that it is difficult to form an opinion 

 upon the point. The distinction drawn by llance (Joum. Bot. 1875, 365) between 

 Pasania and Cyclobalanus, founded on the male flowers of the former being tomernlate 

 and of the latter being solitary, breaks down here, for the male flowers of this are 



solitary.
