The rigid, coriaceous, very peculiar and striking aspect which the 

 sterile part of this Fern presents, is not unlike some species of the 

 genus Ficus. We were not fortunate enough, during a short excursion 

 into the interior of Luzon, to detect the fertile fronds.

Presl, in his Tentamen Pteridographiae, in defining this genus, 

 divides the species into two groups, viz. : " § I. Gymnopteris. — Frons 

 cipice fertilis aut frondes dissimiles. Vence internee aut prominulce. 

 Venulce in maculas Tiexaganoideas anastomosantes." Under this section 

 he enumerates Q. spicata and five other species. " § II. Anapausia. 

 Frondes dissimiles, coriacece aut lierbacece. Vence internee aut elevatee 

 costwformes. Venulce in maculas transversim et irregulariter parallelo- 

 grammas lateribus curvatis anastomosantes." To this last section belong 

 the Q. latifolia and nicotiancefolia, with other two allied species.
