Has. Cerro del Tamber, Guatemala, where the average tempe- 
rature of the climate is 68°—69°. G. U. Skinner, Esq. 
For the knowledge of this splendid fruited oak, which attains 
aheight of 80 feet, we are also indebted to G. U. Skinner, Esq- 
The acorns are even larger than those of Q. Skinneri, (see our 
preceding plate) and the foliage and the cupula, especially, are 
_ quite different: the latter singularly rough and corrugated. Mr. 
__ Bentham observes that the cotyledons of the embryo are unequal 
__ insizeand slightly uneven on the surface, but that there is nothing 
Tike the dissepiments and furrows of Q. Skinneri, and only a few 
very slightly prominent ribs on the endocarp.
