I have examined the type of this species in the DeCandolle Herbarium, and 
also the type number of Quercus companoana Vidal at Kew, and although the type 
of Quercus llanosii is a flowering specimen with leaves 20 cm in length, and the 
type of Q. companoana is a specimen with immature fruits and with leaves 8 to 
13 cm in length, I am disposed to consider the two species identical, and ac- 
cordingly here reduce Vidal’s species. The account of the fruit and Blanco’s 
synonyms must be excluded from DeCandolle’s description of the species, as 
Quercus concentrica Blanco appears to be referable to Q. soleriana. This may 
be the species determined by Blanco as Quercus cerris, as suggested by Vidal. 
Koorders has reported this species from Celebes, under Q. companoana Vidal. 
4. Quercus luzoniensis sp. nov. 
Arbuscula vel arbor parva subglabra; ramis teretibus, lenticellatis, 
ramulis glabris, nigricantibus ; foliis alternis, coriaceis, integris, 4 ad 6 
cm longis, oblongo-lanceolatis vel elliptico-lanceolatis, breviter acuminatis, 
basi acutis, supra nitidis, subtus glabris vel minutissime griseo-puberulis ; 
cupulis circiter 1 cm diametro, utrinque cinereo-pubescentibus, squamulis 
imbricatis, acuminatis, adpressis, circiter 1.5 mm longis ; glandibus conico- 
ovoideis, glabris, nitidis, apiculatis, circiter 1 cm altis crassisque. 
A shrub or small tree about G m high, nearly glabrous. Branches 
terete, lenticellate, brownish, the branchlets somewhat angled, slender, 
glabrous, blackish when dry. Leaves alternate, oblong-lanceolate to ellip- 
tical-lanceolate, 4 to 6 cm long, 1.5 to 2.5 cm wide, the apex rather 
gradually short-acuminate, the base acute or slightly decurrent-acuminate, 
the margins entire, recurved, coriaceous, the upper surface glabrous, 
shining, the lower surface slightly paler, dull, glabrous or very minutely 
grayish-pubendent ; nerves about 7 on each side of the midrib, obsolete 
or nearly so above, distinct beneath, the reticulations obsolete or nearly so; 
petioles about 5 mm long. Inflorescence unknown. Fruits in short 
spikes, terminal or in the ’upper axils; involucre about 7 mm high, 
abruptly narrowed below into a stout stalk, about 1 cm in diameter, 
rather densely gray-pubescent on both surfaces, the scales lanceolate, 
acuminate, alternate, imbricate, not arranged in concentric lines; glans 
ovoid-conical, glabrous, shining, about 1 cm high and the same in 
diameter, apiculate.
