THE NEWEK EVERGREEN ORNAMENTAL TREES. 529 
T. ericoides (the Heath-like yew). — A very pretty, slender 
Syn. variety, with very minute foliage, quite dis- 
t. microphyiia. tinctive and hardy here, and at Newport, 
T. Hibernica (the Irish yew). — The same as Fastigiata , a very 
striking pyramidal tree, resembling in its close compact habit, 
the Lombardy poplar. There are specimens in England twen- 
ty-one feet high, though usually twelve to fifteen feet seems its 
common height ; it is also known as the Florence Court yew. 
It is quite hardy generally, though sometimes a little browned 
by severe winters. This is a most admirable variety for pot- 
culture. 
T. nana (Dwarf yew). — -A very dwarf, hardy variety, never 
Syn. exceeding two or three feet, but very spreading, 
T. Foxii. like the Prostrate juniper. 
T. variegata (Variegated yew). — A handsome variety, differ 
ing a little from the Golden yew, and sometimes sold as T. ele- 
gans ; hardy here. 
Thuiopsis. Broad-leaved arbor vitas. 
Name derived from Thuia, arbor vitae, and opsis, like. There 
is but one variety of this new genus recognized in Gordon’s 
Pinetum, viz., Thuiopsis dolabrata . The remaining variety, 
known in this country as Thuiopsis borealis , is classed by Mr. 
Gordon among the Cupressi , and has already been described by 
us as a most valuable and hardy tree, known as Cupressus 
Nootkaensis. We think, ourselves, it would be better to adopt 
the nurserymen’s name, Thuiopsis Borealis, by which it is gen- 
erally invoiced. 
Thuja. The Arbor vita:. 
So many of this family have been already described under 
the head of Biota, and Mr. Downing having said all that was 
necessary upon the common American arbor vitae ( Thuja occi - 
dentalis), but few distinctive Thujas remain for us to mention. 
Thuja gigantea (Gigantic arbor vitae). — If this, succeeds in 
Syn. the United States — and there is every 
T. Cratgiana- reason to be satisfied with its success 
T. Libocedra3 decurrens. .... . 
thus far — it will unquestionably be the
