Abies nigra. — Ad ornamental tree, with shorter leaves and 

 branchlets ; of more compact habit and darker hue than A. alha. 



Abies pyramidalis is said to be a French variety ; it differs from 

 the species in being remarkably fastigiate and of very compact 

 growth. 



Abies Hookeriana. — The late Andrew Murray described this in 

 Lawson's " Pinetum Britaunicum " as an Alpine, with a spreading 

 and irregular, but remarkably graceful habit; thickly branched, 

 and clothed with light feathery foliage; " leaves slightly curved, 

 with a rib in the middle, and sometimes depressed above, so as to 

 give the leaf a triangular, or boat-shaped form ; rich, grassy- 

 green above, pale green and very slightly silvery beneath, except 

 when young and fresh ; closely but irregularly set along the young 

 branches, chiefly on the upper side, except at the extremity of the 

 shoot, where they surround the whole twig." 



Abies lasiocarpa. — Known also as A. Lowiana, and A. Parsonsi, 

 A handsome, quick-growing species. 



Abies magnijica. — A noble tree, quite hardy ; sometimes known 

 as A. nobilis robusta. 



Abies Menziesii appears to thrive best where the soil is moist 

 the greater part of the year. It is an ornamental species, with 

 sharp-pointed leaves, which are silvery beneath. 



Abies Mertensiana (California Hemlock Spruce). — This forms 

 a roundish conical head, is very dense and compact in growth, 

 and remarkably graceful in the arrangement of its branches. 



Abies robusta. — A variety of A. nobilis, the Noble Silver Fir, 

 which Douglas styled " beautiful and immensely large trees." 



Abies Morinda Smilhiana. — A remarkably beautiful tree, not 

 unlike the Norway Spruce in shape and character, but more 

 graceful in growth and delicate in color. 



Abies nobilis (the Noble Silver Fir) is quite vigorous in 

 growth, beautiful in verdure, regular and graceful in form, of 

 large size ; it has ivy-colored, dark green leaves, Avith horizontal, 

 outspreading branches. 



AJnes Nordmanniana. — A handsome tree, with ample branches 

 and brightly varnished foliage. The growth is vigorous, regular, 

 and graceful in form. 



Abies orientalis (Eastern Spruce). — This has been classed as a 

 variety of A. alba and also of A. excelsa. It is of a regular, 

 conical form, and so thick and close as to be considered a perfect 

 model of the compact form of conifers.
