figured by Cavanilles, to the crenated heartsliaped form which I have 

 described as the variety ft. This and the variety y. ) long considered 

 as distinct species , the cup however the least changeable organ of 

 this polymorphous genus, and its scales, are similar in all the va- 

 rieties. On the arid hills of Valencia and Grenada it assumes the 

 form described by Cavanilles, its more normal appearance is that fi- 

 gured by Olivier, whilst in Ihe fertile valleys of Andalusia and at the 

 base the Djibbel Kibir it becomes the ft and y of this catalogue.

Obs. I did not myself meet with this species, but I have thought 

 it right to insert it here in order to give as above its very intricate and 

 little known synonymy. As Desfontaines describes his plant with 

 deciduous leaves, and Santi his as an evergreen, the learned Rei- 

 chenbach with reasonable doubts is inclined to consider them as dis- 

 tinct, (Fl. exc. vol 1. pag. 177) but this difference depends as in Q. 

 Lusitanica , Q. humilis and other subperennant species, on the greater 

 or less rigour of the climate. Its leaves , its stiffer fastigiate habit, 

 the turbinate form of its cup, and the much shorter bristles of its 

 scales, togetherwith its suberosily, sufficiently distinguish it from Q. 

 Cerris , which like itself has been parcelled out into a multitude of 

 supposed species. I have compared the authentic specimens of Des- 

 fontaines with samples cut from the original Lucombe or Exeter oak, 

 and find them identic. The seedlings raised from the- parent tree vary 

 considerably, and as it bears fruit very young we may expect to 

 meet with many garden varieties. In fact the leaves of this genus af- 

 ford characters of form only on a large and general scale , and the 

 quantity and even the quality of their down is a very minor conside- 

 ration. The most stable characters are those taken from the shape 

 and scales of the cup, and its relative size as to the acorn : yet these 

 sometimes vary , for nothing is so unchangeable in nature as to be
