tomentose within, and covered with closely appressed tomentose scales, reddish at 

 their apices, those at the margin of the cupule minute, gradually increasing in size 

 and thickened towards the base. 



The above description is taken from specimens in cultivation, which show 

 considerable variation in the shape of the leaves. Herbarium specimens from 

 Mexico show greater variation, and have been grouped by De Candolle into three 

 forms, the type and two varieties, pandurata and Hartwegi. 



This species appears to be widely spread in the mountains of southern Mexico, 

 where it was discovered by Humboldt near Ario, at an elevation of 6000 ft. He 

 describes it as a lofty tree, 3 to 4 ft. in diameter, with very thick deeply cracked 

 bark, and very compact strong wood, susceptible of taking a fine polish. Galeotti 

 found this oak in the woods and savannas of Mirador and Zacuapan at 2500 to 

 3000 ft. altitude. It was collected by Hartweg at Tuxpan near Anganguio, by 

 Bourgeau near Santa F^, and by Berlandier between Tula and Tampico. Seemann 

 found it also on the Cerro de Pinal in northern Mexico. 



Specimens of this oak, described by Bentham as Q. Hartwegi, were sent by 

 Hartweg to the Horticultural Society in 1839; and seedlings probably were raised 

 in the Chiswick Garden, though there is no definite record of its cultivation.

The finest specimen which we have seen is a tree in the Cambridge Botanic 

 Garden, which is grafted on the common oak. It retains its leaves till March or April, 

 and does not appear to suffer from severe winters. In 1908, a favourable season, it 

 bore well-formed acorns ; but in 1 909 none of the fruit ripened, 



A small tree, about 1 2 ft. high, at Kew, was obtained from Smith of Worcester 

 in 1873. It has long borne the label Q. genuensis \ but this appears to be an abbre- 

 viation of Q. rugosa ^ genuensis, the name applied to a tree at Glasnevin, about 1 6 ft. 

 high, which was obtained from the same firm in 1885. 



At Kilmacurragh, Co. Wicklow, there is a good specimen, reported by Capt. 

 Acton to be 36 ft. high and 2 ft. 8 in. in girth. Its history is unknown. 



This species is also in cultivation at Westonbirt ; where a number of uncommon 

 oaks were planted in Silkwood by the late Mr, Holford, on soil too dry and thin to 

 enable them to develop themselves. (H. J. E.)
