LAVENDER §. 
The general aspect of the various species which compose this 
genus of labiate plants, although presenting very characteristic 
differences, merges gradually from one species to another ; all are, 
in their native habitat, small ligneous undershrubs, from 1 to 2 feet 
in height, with a thin bark, which detaches itself in scales; the 
leaves are linear, persistent (until the stems become woody), and 
covered with numerous hairs, which give the plant a hoary 
appearance. The most commonly known species are Lavandula 
vera, L. spica, and L. Stechas. 
Commercially the Z. vera is the most valuable by reason of the 
superior delicacy of its perfume; it is found on the sterile hills 
and stony declivities at the foot of the Alps of Provence, the lower 
Alps of Dauphiné and Cevannes (growing in some places at an 
altitude of 4500 feet above the sea-level), also northwards, in — 
exposed situations, as far as Monton, near Lyons, but not beyond 
the 46th degree of latitude; in Piedmont as far as Tarantaise, and 
in Switzerland, in Lower Vallais, near Nyon, in the Canton of 
Vaud, and at Vuilly. It has been gathered between Nice and 
Cosni, in the neighbourhood of Limoné, on the elevated slopes of 
the mountains of Western Liguria, and in Etruria on hills near 
the sea.
