the resin-canals in the parenchyma of the leaf, and possesses very little- 

 hypoderm. The same characters are given by Bertrand for Yeitchii, 

 so that there can be no doubt that we have both had the same plant 

 under examination. The Veitchii from Yeitch's I^ursery ; Royal 

 Botanic Garden, Edinburgh ; Mr. Syme, Elvaston Nurseries ; and the- 

 Lawson jSTursery Co. (Limited), Edinburgh, is quite distinct, having 

 the resin-canals, close to the lower epidermis, and the hypoderm well 

 developed. In the absence of sufficient materials for description, as- 

 the cone remains unknown, I would provisionally name it Pinus- 

 Harryana, after Mr. Harry Yeitch, the head of the firm of Yeitch & 

 Sons. 



The leaves of this species rather closely resemble in general form 

 and appearance those of Pinus (Pseudotsuga) Fortunei, Murray, and 

 it seems not improbable that it may have been confounded with that 

 plant under the name of Jezoensis. It is a Japanese species, but is- 

 not A. Jezoensis, Sieb. et Zucc, to judge from the figure.

Shoots hairy or smooth. Leaves inserted singly all round the stem, 

 but bent so as to form two lateral rows, a few directed upwards and 

 downwards. Leaf long and linear, twisted above the base, narrowed 

 towards the orbicular insertion, width uniform, the apex bifid, with 

 two narrow sharp points, iipper surface deep green with no stomata, 

 beneath with a more or less conspicuous band of stomata on each side 

 of the midrib, there being from 7 to 8 rows in each band. Leaves from. 

 1 to 2^ inches long, and about iV inch wide. Buds resinous, covered 

 with brownish scales. 



Transverse section of leaf. — Leaf flattened, four times as broad as 

 thick, sides rounded, upper surface with a slightly marked longi- 

 tudinal furrow, midrib not prominent below. Hypoderma well 

 developed, forming a continuous, or very nearly continuous, band from 

 the resin- canal of one side, under the epidermis of the upper surface, to 

 the resin-canal of the other side ; the hypoderma is also developed 

 beloAv the fibro-vascular bundles. The resin-canals are placed, one at 

 each side of the leaf, close to the epidermis of the under side. The 

 pallisade parenchyma is well developed on the upper side, and below 

 is the parenchyma with well-marked intercellular spaces communi- 

 cating with the stomata. 



Fibro-vascular bundle double, the parts rather widely separated, a 

 few thick cells developed both above and below ; the whole surrounded 

 by a well-marked sheath.
