822 FOREST CULTURE AND 
Kentia Mooreana, F. v. M.—Dwarf Palm of Lord 
-Howe’s Island, where it occurs only on the summits 
of the mountains. 
Kentia sapida, Blume.—The Nika Palm of New 
Zealand and the Chatham Islands. It also attains a 
height of 40 feet, and is one of the hardiest of all 
palms. The unexpanded flower- spikes can be con- 
verted, as palm-cabbage, into food. 
Lactuca, virosa, L.— Middle and South Europe, 
North Africa, Middle Asia. A biennial. The inspis- 
sated juice of this Lettuce forms the sedative Lactu- 
carium. : 
Lathyrus pratensis, L. — Europe, North and Mid- 
dle Asia. The Meadow Pea. A good perennial 
pasture-herb. 
Lathyrus sativus, L. — Middle and South Europe. 
The Jarosse. An annual forage-herb; the pods also 
available for culinary purposes. Probably other spe- 
cies of Lathyrus could advantageously be introduced. 
Lavandula angustifolia, Ehrhart. (L. vera, Can- 
dolle.) —Countries around and near the Mediterra- 
nean Sea. The Lavender-plant, of somewhat shrubby 
growth, from which, by distillation, the best oil of 
lavender is prepared. It lives on dry soil, but is less 
hardy than the following. 
Lavandula latifolia, Villars. (LL. spica, Candolle. )— 
South Kurope, North Africa. Also from this species 
much layender-oil is obtained. 
Lavandula Steechas, L.—South Europe, North Af- 
rica. This shrub can also be utilized for oil-distilla- 
tion and other purposes, for which the two other 
lavenders are used. The quality of the oil of these 
species seems to differ according to their locality of 
growth.
