54 SUPPLEMENT TO THE PINETUM. 



more or less twisted at the base, rather distant and strictly 

 arranged in two horizontal rows along the shoots, and from 1 1 to 

 2 1 inches long, and one line broad, blunt pointed, or with a slight 

 notch in the centre, particularly those on the adult trees, and 

 all of a dull glaucous green above, but much paler, and with 

 two faint glaucous bands below, between the elevated mid-rib 

 'and thickened margins. Branches in distant whorls, horizon- 

 tally placed, and rather slender; branchlets more or less op- 

 posite, quite smooth, slender, laterally placed in two horizontal 

 rows, and of a pale yellowish colour. Cones from 3| to 5 

 inches long, and 1|- inch broad; erect, cylindrical, obtuse at 

 the point, rounded at the base, of a pale brown colour, and 

 emitting numerous transparent resinous tears externally, and 

 very similar in shape and general appearance, but somewhat 

 larger than those of Picea grandis ; scales broad, more or less 

 crescent-shaped, rounded on the outer side, incurved round the 

 margins, woolly on the exposed parts, tolerably equal in size, 

 and deciduous when fully matured; bracteas very minute, 

 dorsally placed at the base of the scales ; broader than long, 

 somewhat rounded, wedge-shaped on the upper part, toothed 

 or fringed round the edges, and with a prolonged sharp point 

 in the centre ; seeds angular, soft, and with a broad hatchet- 

 shaped persistent wing. 



A noble tree, frequently upwards of 250 feet in height, and 

 5 or 6 feet in diameter, found in British Columbia and Northern 

 California, but always in valleys or along the alluvial banks of 

 rivers. 



This new and very distinct species appears to have been first 

 discovered by Mr. William Lobb, who mistook it for the Picea 

 grandis of Douglas ;* an error easily accounted for, on account 

 of the great similarity of the cones and usual habitat of the 

 tree, both kinds being always found in damp valleys, or along 

 the alluvial banks of rivers, and never as mountain trees. It 

 is to be found in nearly all the Nurseries, and in many private 



The original plant of Picea grandis^ at Elvaston, raised in 1831, from 

 Douglas's se^ds, proves the identity of the true kind.
