THE ANATOMICAL STRUCTURE OP THE LEAF. 105 



carpa. It was described in 1862 by Mr Gordon as Picea Lowi- 



No. 21 (105). Pinus (Abies) Veitchii. 



Pinus selenolepis, Parlatore. 

 Abies Veitchii, Carriere. 

 Picea Veitchii, Lindl. 



Leaves obtuse and emarginate at the apex. Stomata on the 

 under surface of the leaf only. Hypoderma wanting. Resin 

 canals in the parenchyma of the leaf. 



Only a single specimen of the remarkably distinct form has 

 been seen. It is in Kew Herbarium, and bears two labels, 

 " Abies microsperma" and "Picea Veitchii (Lindl.)." It has no- 

 thing to do with the Abies Veitchii in cultivation. 



No. 22. Abies Harryana. New species. 



Abies Veitchii, Hort., Yeitch. Not of descriptions. 



Leaves acute at the apex. Stomata on the under surface of the 

 leaf only. Hypoderma forming a continuous or almost continu- 

 ous layer under the epidermis of the upper side of the leaf. Resin 

 canals touching the epidermis of the under side. 



This is the plant cultivated as A. Veitchii, and sent to me under 

 that name by Messrs Yeitch. It differs in appearance from true 

 Veitchii, and can be at once separated anatomically by the great 

 development of the hypoderma, and by the position of the resin 

 canals. If further investigation confirms the opinion that it is 

 new, the name Harryana will be retained in compliment to Harry 

 J. Veitch, Esq., the head of the firm of Veitch & Sons, in London. 



No. 23. Abies sp., from Drummond. 



A single plant, in the Royal Botanic Garden, Edinburgh, has 

 been examined, and I fail to refer it to any of the forms already 

 noticed. 



Pseudotsuga, Carriere. 



Leaves not in cushions, but inserted directly into the stem, as 

 in Abies. Two resin canals, one on each side of the leaf. Fibro- 

 vascular bundle single.
