Though it has not been possible to examine the type of Dion- 
cophyllum Tholloni there can be little doubt that the Sierra 
ne plant is conspecific with it. It is true that Baillon 
described D. Lholloni as quite glabrous, but the peltate scales 
are minute, and though ieadily observable through a lens on 
them or of leaves unprovided with an apical pair of hooks. 
it is desirable to attempt a morphological interpretation of its 
uliar leaves. On careful examination of the hooked leaves 
ea of the long-shoots), a minute cusp can be seen at the 
pe but stated that the presence of tendrils suggested Passi- 
oraceae;+ Gilg also referred it to the Flacourtiaceae, but 
regarded it as representing a new group of that family.t 
As the only material of Dioncophyllum in the Kew Her- 
barium consists of two flowerless shoots, the details of the floral 
morphology cannot at present be confirmed. Judging from 
Baillon’s description, however, the genus should be referred to 
the Passiflorales,§ but cannot yet be assigned to any family.
