P. nigra. Black Spruce. (L r) A native variety of pyramidal form, not 

 unlike P. excelsa. Foliage light green. Suitable for light, dry soil, and does 

 well in the northern states. 



P. orientalis. Eastern Spruce. (L v) Perfectly hardy; form pyramidal; 

 foliage dark green, much richer than the Norway Spruce, though resembling it 

 somewhat. One of the best evergreens ; valuable for group or specimen 

 planting. Should be in every collection. 



P. orientalis, var. gracilis. Graceful Eastern Spruce. (VD s) A variety 

 dwarfer than Remonti. Form conical and compact ; foliage dark green and 

 very small. 



P. pinsapo. Spanish Fir. (Ms) One of the most interesting of rare 

 conifers. A good grower; form pyramidal; foliage light green ; leaves sharp 

 and stiff, being set entirely around the branches. 



P. pungens. Colorado Spruce. (L r) A noble tree from the Rocky 

 Mountains. Hardy in any exposure ; a good grower ; branches stiff and 

 close ; foliage light green. A valuable lawn tree. 



P. pungens, var. glauca. Blue Colorado Spruce. (L r) A form of 



P. pungens with the same general character, but foliage of an exceedingly rich 

 silvery blue. One of the most valuable trees for ornamental planting, giving 

 a very distinct color note in any situation. (See plate on page 7.) 



P. pungens, var. Kosteriana. Koster's Blue Spruce. (L r) A form of 

 P. pungens. Foliage steel-blue; color quite uniform, as they have been propa- 

 gated by grafting. 



P. pungens, var. glauca pendula. Weeping Blue Spruce. (M v) A 

 tree of great merit, combining with all the desirable features of the Blue 

 Spruce a distinct weeping habit. Rare and interesting. 







PINUS. Pine 



Included under this genus are many of our noblest forest and ornamental 

 trees, suitable for all soils and situations ; they are, however, rather impatient of 

 stagnant moisture, and generally succeed best on good, well-drained land. We 

 have been careful to mention only those species and varieties which are known to 

 be perfectly hardy in this climate. As all our trees have been frequently transplanted 

 and are well furnished with roots, satisfactory removal is assured. 



P. Austriaca. Austrian Pine. (L r) Rounded form; vigorous growth; 

 glossy dark green leaves. One of the most important for specimen or mass 

 planting, and exceptionally good for windy exposures and as a shelter to pro- 

 tect less hardy varieties. It is also a good tree near the seacoast. (See plate 

 on page 17.) 



P. Cembra. Swiss Stone Pine. (Ss) A perfectly erect form, regularly 

 branched from ground to top, forming a handsome conical tree. Long foliage 

 of silvery green. (See plate on page 17.) 



P. excelsa. Bhotan Pine. (L r) A noble tree. In general it resembles 

 the White Pine, but its longer, more silvery leaves are pendulous and grace- 

 ful. It is not particular as to soil or situation, but requires space for proper 

 development. Makes a grand specimen.
