TSUGA. Hemlock 
Of all evergreen species none surpass the Hemlocks. Their absolute hardi¬ 
ness, rapidity of growth, good transplanting qualities, together with their beautiful 
forms and fine foliage, have made them general favorites in all sections. 
T. Canadensis. Hemlock. (L r) One of our finest native evergreens, so 
well known as to need little description. Form pyramidal ; branches some¬ 
what pendulous and delicate; the dark green foliage light, yet tufted. Valu¬ 
able for specimens, mass planting and hedges. 
T. Canadensis, var. gracilis. Graceful Hemlock. (Ss) A slender form 
of Hemlock, with much smaller foliage than T. Canadensis. 
T. Canadensis, var. Sargenti pendula. Weeping Hemlock. (Ss) A 
beautiful variety of distinct weeping habit, making a low, broad specimen. 
Very desirable. 
T. Caroliniana. Southern Hemlock. (L r) Of distinct pyramidal growth, 
with dense, dark green foliage. 
T. Hookeriana. Alpine Hemlock. (il / f m) A beautiful variety, native 
of the northwest. Form conical ; branches long , somewhat pendulous ; foli¬ 
age dense, of a rich bluish green, that of some specimens coloring as well as 
that of the Blue Spruce. A valuable addition to ornamental evergreens
