17. SHOREA TEYSMANNIANA Dyer. 
Luzon: Cagayan, Ilocos Norte, Nueva Ecija, Bulacan, Laguna, Tayabas, 
Camarines, Sorsogon. Polillo. Mindanao: Agusan. 
This species has not yet been found in flower or fruit. 
18. SHOREA SCROBICULATA Burck. 
Luzon, Tayabas Province, For. Bur. 22712, July 30, 1914. This differs 
from the type of Shorea scrobiculata in having generally smaller leaves 
and fruits and in the longer and more slender wings to the fruits. Its 
general appearance is so like the species, however, that it is thought best 
to place it with S. scrobiculata, for the present. Credited with being a 
yacal. This species has, till now, been known only from Borneo. 
19. SHOREA NEGROSENSIS Foxw. 
Luzon : Cagayan, Isabela, Laguna, Tayabas, Albay, Sorsogon. Negros. 
Mindanao: Surigao, Agusan. 
20. SHOREA PLAGATA sp. nov. § Anthosliorea. 
Arbor magna, 40 m alta, 90 cm diametro. Cortex nigro, cras- 
so, squamuloso. Folia coriacea, ovato-lanceolata vel elliptica; 
lamina 6 ad 12 cm longa, 3 ad 5.5 cm lata ; petiolo 12 ad 15 mm 
longo, nigro. Nervis secundariis 9 ad 12, plerumque 10. Stipu- 
lae parvae, fugaceae. Paniculae terminates. Flores ignota. 
Fructus ovoideus, sericeus, 12 ad 15 mm longus, 11 mm diametro. 
Ovarium, conoideum sericeum. Stylopodium 0. Stylus conicus, 
sericeus. Alae 5, 3 majora 7 cm longa, 12 ad 16 mm lata; nerviis 
longitudinalis 7 ad 10, reticulatis. 
A very large tree with thick black, furrowed or scaly bark. 
Heartwood dark red, moderately hard and light. A fine grade 
of red lauan but harder and heavier than is usually the case with 
that wood. It has some resemblance to guijo and is locally 
known by that name. It grows with other Dipterocarps in tall 
forest. The fruit, when fresh, showed a distinct reddish tinge 
in the wings, the nut being covered with a pate silky pubescence. 
The fruit is eaten by the forest animals very quickly after its fall. 
Mindanao, Zamboanga District, Port Banga, For. Bur. 13758, Fox- 
worthy, De Mesa & Villamil, June 17, 1912 (type). This species was first 
collected by Whitford & Hutchinson, Por. Bur. 917 1, 9193', in the same 
neighborhood, in December and January, 1907 and 1908. More recent 
collections have been (all of them from the same part of the Zamboanga 
Peninsula) : For. Bur. 11210, Foxworthy, De Mesa & Villamil, June, 1912 
(with the name malacayan Colorado) ; For. Bur. 20266, Stadtmiller & 
Ferraris, January, 1913. 
The specific name “plagata” is given because of the resemblance of the 
leaves to those of Hopea plagata. It is allied to Shorea selanica Blume 
and apparently also is rather closely related to Shorea warburgii Gilg.
