 Ham. MSS. ; Q. ferox Rox. Hort. Beng. p. 68. This species, according to 

 Sir J. E. Smith, was discovered by Dr. Buchanan (Hamilton) in the forests 

 of Upper Nepal, flowering and fruiting at various seasons. Dr. Buchanan sup- 

 posed it to be an oak ; and he describes it as being a tree with smooth branches, 

 and leaves on short footstalks, lanceolate, more or less ovate, entire, taper- 

 pointed, somewhat unequal at the base, about 4 in. long, 1$ in. broad ; rigid, and 

 rather coriaceous, with irregular, distant, slightly curved veins ; the upper surface 

 polished, and the under one paler, and opaque. The flowers are generally 

 monoecious (though Dr. Buchanan observed one tree with only female 

 flowers), in slender, downy, clustered, axillary or terminal spikes ; the male 

 spikes being the more numerous. Stamens about 8, with a dotted central disk. 

 The calyx of the fruit is armed with very numerous, rigid, prominent, sharp 

 thorns, a fourth of an inch or more in length, spreading in every direction.
