Folia primaria plantulae juvenilis suborbicularia, grosse et irregulariter sinuata, 

 interdum dentibus nonnullis pungentibus munita, lamina ad 2 cm longa et lata, 

 petiolo circ. 2 cm longo apice vel paulo infra distincte articulate Spinae sat 

 mites, nondum pungentes, plerumque simplices, rarissime segmentis I — 2 laterali- 

 bus munitae, 3 — 5 mm longae. Ramelli foliigeri brevissimi, distantes. Folia 

 secundaria anguste obovato-elliptica — elliptico-lanceolata, coriacea, discoloria sub- 

 tus pallida, obtusa, basi manifeste angustata, reticulato-nervosa; lamina 2 — 3,5 cm 

 longa et 0,6 — 1,3 cm lata; petiolus tenuis vulgo 2 — 3, rarius ad 6 mm longus, 

 paulo supra basin articulatus. Cetera ignota.

 ° c— d B. corymbosa: c ordinary leaves, d exceptionally narrow leaves. All natural size. 



Masafuera: Q. de las Casas, one seedling by the side of a waterfall, 

 215 m; larger shrubs seen on the wall of the canyon in an utterly inaccessible 

 place, but some branches were obtained by means of a lasso (no. 503); Q. de 

 la Loberfa, one shrub on a steep rock in the stream. 



Unfortunately, all specimens observed were sterile. B. masafuerana comes 

 very near B. corymbosa, but differs in the colour of the cortex, in the much 

 narrower and more coriaceous leaves and in the slender habit. I have never 

 seen anything like this form in Masatierra, so I am confident that the flower 

 and fruit will offer structural differences. 



Area of distribution: Endemic in Masafuera.
