The local names here given have been taken from collectors’ 
notes, as found with herbarium specimens. In spite of the ex- 
tensive field work that has been done during the past fifteen 
years, a number of forms that are locally of some importance 
remain but little understood botanically. 
The most important of these is mangasinoro, which is a widely 
distributed lauan. It seems to be produced by more than one 
species of Shorea, but we lack flowering and fruiting material 
sufficient for its identification. Kalliot and yamban seem to be 
of importance locally, but are not well understood. They seem 
to include guijos, dalingdingans, and yacals and are found in 
Zambales, Pangasinan and La Union Provinces, Luzon. A con- 
siderable amount of additional collecting is needed to straighten 
out these names. 
A certain amount of confusion is caused by the duplication of 
names in different regions. Thus mayapis, which seems to have 
been the best-known name for Anisoptera thurifera in Bulacan, 
Pampanga, Zambales Provinces and in parts of Rizal and Bataan 
Provinces, is the name applied to Shorea squamata in the rain 
forest of northern Laguna Province and in a part of Tayabas 
Province. The two species are very distinct in appearance, struc- 
ture, uses, and habitat. 
Anisoptera thurifera is also known through a part of its range 
as palosapis, and the largest part of the wood to reach the Manila 
market during the past six years has come in under this name.
