A. noliJis in cultivation presents tlie followingcliaracteristics : — 

 Brandies verticillate. Young shoots reddish brown, hirtellous. 

 Buds ovoid-oblong, brown, more or less resinous. Scales obloug, 

 the lower ones pointed. Lateral shoots spreading horizontally, 

 oblong obtuse in outline, more or less four-sided (not flat) owing 

 to the arrangement of the leaves. Leaves densely crowded in 

 several rows, those on the lower surface twisted at the base so as 



to bring them into the horizontal position, and allowing the 

 reddish-coloured bark to be seen between their bases ; those on 

 the upper surface more or less curved, assurgeut with the 

 points directed either upwards or away from the apex of the 

 branch, i. e. towards the trunk, entirely concealing the surface 

 of the shoot, and giving it the appearance of a flat brush, 

 the leaves representing tlie bristles. The typical nolilis may 

 generally be recognized by its flattish, broadly linear leaves 

 grooved on the upper surface (see PI. lA^, top fig.), either at the 

 base only, or for tlie greater part of its length, with whitish bands 

 of stomata, on the under surface only or on both. The cones are 

 couoidal, rarely cylindric, and the bracts projecting, acuminate^
