has non-edible fruits, and otherwise agrees with Blanco’s descrip- 
tion. On account of these data I am obliged to differ from all 
other authors in my interpretation of Calamus mollis Blanco. 
Beccari, Ann. Bot. Gard. Calcutta 11 (1908) 212-215, has inter- 
preted Calamus mollis as a distinct species of Calamus, with 
C. haenkeanus Mart. as a synonym. Naves reduced Calamus 
mollis to C. haenkeanus Mart. From the data and abundant 
material now available here I cannot agree with this interpreta- 
tion of Calamus mollis Blanco, but am forced to the opinion that 
Calamus mollis Blanco is identical with Daemonorops gaudichau- 
du Mart. and that Calamus mollis of Beccari and other authors 
is Calamus usitatus Blanco, a species that was erroneously 
reduced by Beceari to Daemonorops gaudichaudii Mart.

Caryota urens Linn. does not occur in the Philippines, and 
Martius was correct in referring C. wrens Blanco to C. cumingii 
Lodd. It is widely distributed in the Philippines at low altitudes 
and is generally known to the Tagalogs as pugdhan, sometimes 
as taquipan, and to the Visayans as taquipan and patican.

cited specimens! (Arenga mindorensis Becc.!). 
Blanco’s species was considered by Naves as Wallichia tremula 
Mart., which was based on Blanco’s description. It is absolutely 
certain that Caryota tremula Blanco is the species described by _ 
Beccari as Arenga mindorensis, and that the specimens referred 
by Beccari to Arenga tremula (Blanco) Becc., and the descrip- 
tion given by him, refer to an entirely different species very 
closely allied to, and very probably identical with Arenga ambong 
Bece. Arenga tremula as interpreted by Beccari does not grow 
in any of the provinces from which Blanco secured his botanical 
material. Arenga tremula (A. mindorensis Becc.), as I interpret 
it, occurs in abundance, although locally, in the provinces of 
Bataan, Laguna, Batangas, and Tayabas, and in Mindoro; a very
