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.

 shining, the lower surface slightly paler, dull, glabrous or very minutely 

 grayish-puberulent ; nerves about 7 on each side of the midrib, obsolete 

 or nearly so above, distinct beneath, tlie reticulations ol)Solete or nearly so;
