ADJACENT TO HORTICULTURAL HALL. 37 
Taxus cuspidata, Siedo/d. Aprupt-PoINteD Yew. Is a desirable, tall, 
handsome shrub or small tree with ascending branches, and leaves very dark 
green above and lighter green below. Does not appear hardy, if one may 
judge from its absence in our nurseries. From Japan. 
Thuiopsis. Japanese trees, with whorled pendent branches, the smaller 
twigs being very numerous and 2-ranked. The leaves are opposite, over- 
lapping, or sickle-shaped, and sharply pointed. The small cones have cori- 
aceous, round scales, under which are 5 seeds; the seeds have a notched wing. 
Thuiopsis dolabrata, Stedo/d. HATCHET-LEAVED ARBOR VIT&. Thuja 
dolabrata, Thunberg ; Platycoides dolabrata, Spach.) Tree 40 to 50 feet high, 
with branches drooping at the points. According to Thunberg, “ it is a lofty, 
vast, and beautiful tree, of all evergreens the fairest.”” It requires a rather 
moist situation. The following varieties appear in the collection: nana, Sve- 
bold ; is the Dwarf Hatchet-Leaved Arbor Vit, and also appears in gardens 
and in garden lists under the name of Z7hutopsis dolabrata letivirens. Itisa 
variety seldom over 4 feet high, with the leaves and branchlets of a light green 
color, like an erect Club Moss. The Japanese cultivate it in pots. Also a de- 
sirable rock-work ornament. variegata, Fortune; VARIEGATED HATCHET- 
LEAVED ARBOR VITA; differs from the species in having branchlets and leaves 
of a pale yellow color intermixed. The form known as 7huiopsis borealis, 
Fischer, is Cupressus Nuthkaensis, Hooker, of this Catalogue. 
Thuja. ARsBor ViIT#&. Sexes separated in small clusters, but on the same 
branches, the male (stamens) each having 4 anther-cells, the female clusters of 
a few scales, each of which bears a pair of erect ovules. Spray flat, bearing 
awl-shaped scales and blunt-pointed scales, the latter shorter than the others 
and united to the branch. Gordon’s Pinetum has been mainly followed in 
these species. 
Thuja gigantea, Nuttall. GIANT ARBOR VIT#, YELLOW CyPRESS. 
( Thuja plicata, Lambert ; Thuja Douglasii, Nuttall; Thuja Menziesii, Doug- 
fas.) One of the striking trees of our Northwest coast, growing often 150 feet 
high. The inner bark is used by the Indians to make cloaks, mats, sails, ropes, 
and clothing. It does not appear to be entirely hardy here. 
Thuja occidentalis, Zinmzus. AMERICAN ARBOR VITA, WHITE CEDAR. 
Native; from the cooler parts of Pennsylvania, northward, forming often exten- 
sive cedar swamps. Grows 20 to §0 feet high; yields a pungent oil ; wood is 
durable, but too soft to hold nails firmly. The foliage becomes rather dingy 
as cold weather approaches. It has the following varieties: * argentea, Car- 
riere; has some silvery white color along with the green. compacta, A. 
Smith ; is conical in outline and compact in growth. cristata, Crips ; has 
the crested and spreading small branchlets recurved and cockscomb-shaped. 
densa, Gordon, is the variety compacta of Stendish; a conical bush, with 
stout, compact branches and horizontal, fan-shaped branchlets of a fine glossy 
color. This has also been called 7 huja Caucasica, Hort. globosa, ‘fort. ; 
is a dwarf bush, round in outline and very dense. Hoveyi, Hort. ; Hovey’s 
AMERICAN ARBOR VIT4; is also known as 7huja Hoveyi, Hort. ; a compact 
round bush, with flat spray and branchlets: a slender form, originating in 
America. pendula, Gordon ; branches along the main stem reverted, and 
the branchlets for the most part clustered or tufted towards the end of the 
branches and still more declined. variegata, Loudon; has some of the 
branchlets of a pale yellow. verveneana, //ort. ; a golden-tinted variety 
produced in Ghent. It has produced a new form also.
