THUJA. 407 



rarely showing the gland on the back ; but as the plant 

 matures, they gradually develop, and the leaves become ovate, 

 more closely flattened along the stems, blunt-pointed, and the 

 branches more rounded along the edges, jointed, and two- 

 edged. Branches horizontal, rather short, flattened length- 

 ways, spreading, rather compact, and scattered along the 

 stem, with the smaller or lateral ones alternate, regularly two- 

 rowed, straight, quite flat, and pointing outwards at an acute 

 angle. Branchlets long, straight, linear, flat and two-edged, 

 regularly jointed, and entirely covered with ovate, blunt- 

 pointed, closely flattened leaves, in opposite pairs, as if plaited, 

 with a row of transparent glands along both sides on the back 

 of the leaves. Cones small, solitary, nodding, scattered, and 

 ovate-oblong. Scales elliptic, blunt at the ends, flat, partially 

 furrowed, and mostly six in number, each containing two seeds, 

 inversely heart-shaped, and surrounded by a transparent wing, 

 emarginated at the apex. 



A small tree, resembling the American Arbor- Vita?, thickly 

 clothed with spreading, light green branches, found along the 

 western shores of North America at Nootka Sound, and, ac- 

 cording to some writers, extending into Northern Mexico. 



It is quite hardy, and differs from the common American 

 Arbor- Vitse in having the branches very much shorter, more 

 compact, stouter, and densely covered with small ovate, flat- 

 tened leaves, bluntly pointed, and in four rows, with a plaited 

 or jointed appearance. 



Thuja plicata vapjegata, Carriere, the Variegated Nootka 



Sound Arbor- Vita?. 



Syn. Thuja Wareana variegata, Hovt. 



A pretty variety, only differing from the original form in 

 having a portion of its leaves and lesser spray of a pale yel- 

 low, intermixed all over the plant in a variegated manner, and 

 in its less robust habit. 



It is of French origin.
