270 : SPECIES BLANCOANAE 
pines, the commercial name of its timber being tanguile. Blan- 
co’s specific name does not apply, and his selection of the name 
was probably due to the fact that he had fruits of an entirely 
different plant. His description, otherwise, applies well to the 
species as interpreted, and there is no doubt as to the identity 
of the illustrative material with Blanco’s plant. 
Illustrative specimen from Limay, Bataan Province, Luzon, 
June, 1914, there known as tanguile (Merrill: Species Blan- 
coanae No. 85).

SHOREA GUISO (Blanco) Blume. 
This species is common and widely distributed in the Philip- 
pines, occurring in primeval forests at low and medium altitudes. 
It is a valuable timber tree and the timber is commercially known 
as gutjo, the local name of the tree being guijo or guiso. Ewupho- 
ria malaanonan Blanco has long been a puzzle, but it is now 
perfectly clear that the species described by Blanco is Shorea 
guiso Blanco supplied with large spiny galls. Many specimens 
of this exist in the herbarium of the Bureau of Science, as 
it is very frequently secured by native collectors under the im- 
pression that the gall is a fruit. Blanco describes the “fruit” 
of Huphoria malaanonan as an ovoid pouch bristling with in- 
curved processes which become hard and spine-like at maturity, 
an excellent description of the common gall on Shorea guiso 
Blume. He further states that the “fruit” contained nothing, the 
interior being devoured by insects, modified by the statement 
that in one he did find a single seed; in this he certainly was 
mistaken. In the second edition he repeated the description, 
considering it as possibly a Euphoria, possibly as a Nephelium. 
It is perfectly clear that he placed it in this group on account 
of the spiny galls resembling the fruits of certain species of 
Nephelium. Fernandez-Villar placed it as a synonym of Shorea 
robusta Gaertn., a species that does not extend to the Philippines. 
Blanco’s Euphoria malaanonan has page priority over Mocanera 
guiso, the name-bringing synonym of Shorea guiso Blume, but 
it cannot be adopted in place of the latter as it is based on 
as abnormality; it is further invalidated by Shorea malaanonan 
ume.
