tration from a specimen collected by Dr. Pancic in the mountains 

 of Servia (Plate VIII.). It also occurs in Bosnia and Monte- 

 negro. For the opportunity of doing this and of examining the 

 specimen, I am indebted to Messrs, Proebel of Zurich and to 



Mr. Georg

The shoots have the "pegged" character common to the Spruces, 

 due to the projections at the base of the leai^es, and are moreover 

 covered with short stiff hair. The buds (woodcut, fig. 28) are 

 ovoid conic, dull brown in colour, and invested by ovate-lanceolate 



scales. The leaves are 

 flattish, straight or late- 



rally curved, between half 

 and three quarters of an 

 inch in length, linear, . 

 oblong obtuse, convex, 

 and shining green on the 

 dorsal surface, slightly 

 flattened near the point ; 

 tlie ventral surfiice is 

 marked by a prominent 

 midrib, on either side of 

 which are lines of sto- 

 mata. There is no indi- 

 cation of any twisting of 

 the leaf; hence the sto- 

 mata are really on the 



uppersurfaceoftheblades, p^cea J.U.'-Plan of sectS of leaf^'^uch 



as in some Junipers and "magnified: bud X3; seed X2; leaves, frout 



other plants. A trans- and back, x2. 



verse section, when examined under the microscope, shows a layer 

 of hypoderm-cells beneath the epidermis, and investing the ground 

 tissue of tlie leaf, which consists of spheroidal cells with undu- 

 lating boundary-walls and with a very slight tendency to form 

 palissade-eells on the lower side, that furtiiest removed from the 

 stomata. Close beneath the hypoderm on the lower surface are 

 two resin-canals, one on each side midway between the centre 

 and the margins^ ; each is surrounded by strengthening-cell^.
