74 HARDY CONIFEROUS TREES. 



gives place with age to a bronzy-green tint. It is highly 

 ornamental. 



P. excelsa Gregroryana is of neat and very dwarf 

 growth, rarely being found more than 2 feet high. The foliage 

 is of a pleasant green shade, short, stiff, and arranged thickly 

 on the branches. 



P- excelsa inverta cannot be described as at all an 

 ornamental variety, but it is highly curious and interesting, 

 from the branches hanging down almost close to the main 

 stem, and thus imparting to the tree a strange and striking 

 appearance. 



P. excelsa Maxwellii. A very neat, dwarf-growing 

 form of the common spruce has been sent out under the 

 above name. Unlike several of our well-known pigmy 

 varieties, the shrub in question remains at all times as hemi- 

 spherical as if it had been trimmed by the shears, and never 

 juts into irregular growths, as do many of the dwarf forms 

 that are at present widely cultivated. It only grows 2 feet 

 high, but is full and rounded, and fully i yard in spread. It 

 is said to have originated in a New York nursery, and is rare 

 in cultivation in this country. 



P. excelsa pyg^maea is the dwarfest form of the 

 common spruce, rarely rising to more than i foot in height, 

 but spreading laterally in a disproportionate manner. 



P. excelsa Stricta is of neat and quite compact growth, 

 with glaucous green leaves. It is of unusual habit, but 

 strikingly distinct and ornamental. 



P. Glehnii, Schmidt. Island of Sachalin. Little is yet 

 known regarding this species, which was found by Glehn, 

 who accompanied F. Schmidt in his travels in Sachalin and 

 Amoorland. From the specimen that I have seen, the plant 

 may be described as of rather dense growth, with four-sided, 

 curved, and sharply-pointed leaves, each J an inch long, 

 these being thickly arranged on the branches. The cones 

 are dull brown, and about li inches in length. Scales wedge- 

 shaped, and with the bracts much shorter than these.
