188 ARBORETUM ET FRUTICETUM BRITANNICUM. 
(Dec. Prod.) A shrub, with the habit of a low deciduous tree. Canada 
to Carolina, in rocky dry situations. Height 20 ft. Introduced in 1629. 
Flowers, female dark purple, male greenish yellow and purple; July 
and August. Fruit hairy, purple; ripe in October. Decaying leaves dark 
purple or red, sometimes mixed with yellow. Naked young wood dark 
ae hairy. DeCandolle has characterised two forms of this species as 
ollows : — 
+ R.t. 1 arboréscens. —A tree between 10 ft. and 25 ft. high ; leaf slightly 
downy beneath. 
a R. t. 2 frutéscens.— Shrubby, between 2 ft. and 10 ft. high; and its 
leaf downy and whitish beneath. 
+ R. t. 8 viridiflora. R. viridiflora oir. — Flowers green. Possibly 
nothing more than the male plant. 
Rhias typhina, in British gardens, is either a large shrub, or a low tree with 
a woody stem and a head composed of many irregular branches, generally 
crooked and deformed. The young shoots are covered with a soft velvet-like 
down, resembling that of a young stag’s horn, both in colour and texture ; 
whence, and probably also 
from the crookedness of the 
branches, the common name. 
The cellular tissue of the wood 
is of an orange colour, with a 
strong aromatic odour, and a 
copious resinous juice. The 
leaves are 2 ft. to 3 ft. long, and 
they are very conspicuous in 
autumn, before they drop off, 
when they change to a purplish 
or yellowish red. The flowers 
are produced in close spikes at = 
the ends of the branches ; they 
are often polygamous or di- 
ecious by abortion, and the 
female ones are followed by seeds enclosed in woolly, simple, succulent covers. 
As the plant is of open irregular growth, and not of long duration, it should 
never be placed where it is intended to act asascreen. Like all objects the 
chief beauty of which consists in their singularity, it produces the most striking 
effect when standing alone on a lawn.
