XIV, 3 Beccari: The Palms of the Philippine Islands 329 
the fruit of the latter, however, has a smooth (not granulose) 
surface, the pericarp apparently being without sclerosomes. 
For this reason I have thought proper to transfer it from the 
genus Heterospathe to Ptychoraphis. The fruit is spherical, 
almost centrally apiculate, 7 mm in diameter, and has the hilum 
conspicuously marked all along one side. The spadix is thrice 
branched, and its fruiting branches are thicker than in Hete- 
rospathe data (2.5 to 3 mm in diameter), almost torulose; the 
scrobiculi are approximate, have a raised rim, and the floral 
bracts form a shallow cup; the fruiting perianth is very shal- 
lowly cupular and does not have a pedicelliform appearance. 
The leaflets have slightly falcate apices with no paleolae under- 
neath on the midrib.

After a more complete revision of all the palms belonging 
to the Ptychospermeae I now think it advisable to establish an 
autonomous genus for the Philippine palm which was formerly 
considered by me as a member of the Australian genus Nor- 
manbya, in consideration of the fact that, notwithstanding the 
great similarity in the flowers and fruit, Adonidia differs greatly 
from Normanbya Muellerii in the leaves, the vegetative charac- 
teristics being of great importance in the delimitation of the 
genera of the subtribe of Ptychospermeae. In Adonidia the 
leaflets are regularly set, narrow, elongate, acuminate, bifid at 
the apex, 1-costulate, and with a strong nerve at both margins ; 
whereas in Normanbya the leaflets are very peculiarly arranged 
in groups, each group resulting, apparently, from the spliting 
of one leaflet into several, which yet remain united by their 
bases; furthermore, the resulting leaflets are narrow, have a 
truncate praemorse apex, and have no marginal nerves. 
The separation of Adonidia from No7'manbya gives us a 
genus peculiar to the Philippines and the only endemic one in 
the family.
