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.
