angle of about 50 ; pulvini oblong-linear ; buds sub-globose with brown 

 ovate penilse. Leaves crowded in many rows, ascending at an angle 

 of about 45, curved, linear, four-sided, sharply pointed, the concave 

 sides slightly glaucous, the convex sides green. Cones eylindric or ovate- 

 oblong, 1 2 inches long and O75 inch in diameter ; scales leathery, 

 slightly striated, wedge-shaped, the upper free edge rounded, denticulate ; 

 bracts much shorter than the scale, broadly lanceolate. Seed wings 

 obliquely obovate." Masters in Gardeners' Chronicle XIII. (1880),

 p 176, with fig. 



Like Picea ajanensis with which it is in places associated, P. Glehnii 

 is a northern tree, restricted, so far as at present known, to the 

 southern part of the island of Saghalien, the island of Yeso, and 

 districts in the adjacent coast region of Eussian Manchuria, but 

 nowhere very abundant except around Lake Kucliarro in Yeso where 

 it attains its greatest development. The wood is light and soft, and 

 where the tree is common and easily accessible, it is much used by 

 the natives for all kinds of carpentry. 



Picea Glehnii was discovered during an exploration of the Amur 

 region and the island of Saghalien in the early " sixties ' by the German 

 botanist Friedrich Schmidt who was accompanied by Glehn after whom 

 it is named. Botanically it is described as standing midway between 

 P. obovata and P. Alcockiana, thus forming one of the connecting links, 

 in the series of Piceas which spread across the Euro-asiatic continent 

 from Norway to Japan. According to Beissner P. Glehnii has been 

 introduced into Germany and probably into Great Britain,* but no 

 estimate can be yet formed of its merits as a garden or forest tree 

 in this country. 



Picea nigra. 



A low or medium-sized tree 25 50 feet high, but under exceptional 

 conditions attaining a height of nearly 100 feet with a straight trunk 

 diminishing regularly from the base to the summit. Usually the trunk 

 is slender, often not more than a foot in diameter, covered with 

 reddish brown bark which in the oldest trees growing in Great Britain 

 is fissured into small irregular plates. On the borders of forest lakes 

 Picea nigra is ofteai a stunted tree a few feet high,- and at its northern 

 limit a semi-prostrate shrub. As seen in Great Britain branches 

 spreading and much ramified, the lowermost decumbent, those above 

 the middle more or less ascending. Branchlets short, mostly distichous, 

 but sometimes in pseudo-whorls of three four. Buds small, ovoid, 

 chestnut-brown. Leaves persistent five seven years, spirally crowded, 

 four-angled with short callous tips, straight or slightly curved towards 

 their axis, 0'25 0'75 inch long, with glaucous stomatiferous bands on 



* Of the very few sprays sent to me as Picea Ghhnii some weie indistinguishable from 

 P. Alcockiana, and the others were certainly P. ajanensis.
