of the leaf, sometimes, however, rather low, but always separated by 

 chlorophyll-bearing cells from the lower epidermis. Pallisade tissue- 

 well developed under superior epidermis, the parenchyma with inter- 

 cellular spaces communicating with the stomata, well developed below. 



ribro-vascular bundle double, with one or two thickened cells 

 above and below, the whole surrounded by a well-marked sheath. 



The figure (Plate 47, fig. 12) is drawn from a plant cultivated in 

 Glasnevin Garden, and kindly supplied to me by Dr. Moore. 



This species is cultivated in the Botanic Garden, Glasnevin, and in 

 the Eoyal Botanic Garden, Edinburgh, ujider the name of Pichta. I 

 have also received it from Mr. Syme, of Elvaston ]S^urseries, correctly 

 named sibirica. In Mr. Syme's specimen a single thick hypoderm 

 cell was noticed in one leaf under the epidermis covering the midiib' 

 below.

Shoots and arrangement of leaves not observed. Leaf flat, linear, 

 grooved on upper side, apes obtuse and emarginate, above glaucous 

 green, with no stomata, below with two bands of stomata on each side 

 of the midiib, there being from 6 to 7 rows of stomata in each band. 

 Leaf from ^ to 1 inch long, and about ^V inch broad. 



Transverse section of leaf. — Leaf flattened, about three times as 

 broad as thick, sides rounded, upper surface with a longitudinal furrow, 

 below with a slightly prominent midrib. Hypoderma only slightly 

 developed, a few cells being placed above and below, touching the epi- 

 dermis in the middle line. jSTo hypoderm, or rarely a single thickened 

 cell, at the rounded margin of the leaf. The resin-canals are placed 

 in the middle of the parenchyma. The pallisade parenchyma is well 

 developed above, and the parenchyma with intercellular spaces below. 



The fibro-vascular bundle is double, the tissue between the bundles 

 and the well-developed sheath being thickened. 



The figure (Plate 47, fig. 13) is di'awn fi'om a dried specimen in 

 Eew Herbarium. 



This species does not seem to be in cultivation, and the only speci- 

 men known to me is that in Kew Herbarium. The single specimen 

 has two labels, viz. : — " T^o. 946. Abies microsperma. From Fusi 

 Tami. 2/63. Yokohama;" and " 813. Picea Yeitchii, Ldl. Oldham 

 legit." 



It is undoubtedly the Abies Yeitchii of description, and is perfectly 

 distinct fi'om Abies Yeitchii of gardens.
