THE NEWER EVERGREEN ORNAMENTAL TREES. 529 



T. ericoidcs (the Heath-like yew). A very pretty, slender 

 8yn. variety, with very minute foliage, quite dis- 



T.microphylla. tinct}ve an(1 liard y ^^ and ftt 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 us 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. ijk e t j ie 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 VITJE. 

 Name derived from Thuia, arbor vitas, and opsis, like. There 

 is but one variety of this new genus recognized in Gordon'* 

 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 JBorealis, by which it is gen- 

 erally invoiced. 



Thuja. THK ARBOR VITM. 



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 vitse (Thuja occi- 



dentalis), but few distinctive Thujas remain for us to mention. 



Thuja gigantea (Gigantic arbor vitas). If this succeeds in 



Syn. the United States and there is every 



T. Craigiana. reason to be satisfied with its success
