I have examined the type of this species in the DeCandolle Herbarium, and 
also the type number of Quercus companoan/i 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. solertana. 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.
