 Hab. In Hispania Tarraconensi, et in Lusitania frequens, ubi 



in montibus Cynthia? sive cle Cintra - varielatem pedunculis 



insigniter elongalis adnotavi.

 Hab. Arbor excelsa in alpibus Eliberitanis de la Sierra Nevada, 



in monte Sierra Tejeda , et alibi in Baetica. In montosis ad 



flumen Durium , ad promonlorium Magnum , et in tota 



Lusitania frequens. 



Obs. The geographical expansion of this species is much wider 

 than is generally supposed. I gathered it not only in Spain plentifully 

 but likewise in the woods around the Bosphorus and in the valley of 

 Domouz Dereh on the Black sea. It will doubless be met with in 

 other intermediate points between these widely separated stations.

Quercus prasina Bosc. 



Hab. Non longe a freto Herculeo ad septentrionem \iculi Los 

 Barrios, et ad occasum oppiduli Sancti-Rocci , ubi sylvis 

 Quercus Lusitanicee proceris planities alta atque inculla su- 

 pereminet. In campis aridis Lusilanise media? et meridionals 

 communis. In tractu aspero et ventoso sub vertice montis 

 Magni seu Djibbel Kibir Tingilanorum. 



Obs. This is altogether a southwestern species. I believe the 

 neighbourhood of Gibraltar to be its easternmost station. It entirely 

 covers the arid tracts where it appears, reaching a height of from 6 

 inches to 5 feet , though I have seen at times bushes which had at- 

 tained 12 or more. I have compared it with the plant described by 

 Bosc, and find it to be identic with his Quercus prasina.
