Histoiy, Use, Propagation, CuUui-e, 
Lactucarium, and was first brought into notice by Dr. Duncan, of Edinburgh, who finds it can be adminis- 
tered with effect in cases were poppy opium is inadmissible. Details of the process of collecting and preparing 
the article, will be found in the Caledonian Horticultural Memoirs. (Vol. i. 160-259. ii. 314. and iv. 153.) 
The culture of lettuce as a salad plant is familiar to every one who has a garden. It is sown monthly, or 
oftener, throughout the year, in order to have asuccessional supply, and thinned out or transplanted to increase 
the size and succulency. The latter quality is greatly increased by watering in summer ; and blanching, 
another desirable property, is promoted by tying up the leaves when the plant has attained about two-thirds of 
its usual size. Snails and slugs are very fond of this plant, and should either be watched and hand-picked, 
or the ground well watered with lime water, which effectually destroys them. The lettuce, unlike the cabbage 
and spinage, is a vegetable which can be grown to as great perfection in a warm as in a temperate climate, pro- 
vided it be grown on rich soil, and abundantly supplied with water. Hence the lettuces of Paris, Rome, and 
Calcutta, are as large and tender as those of London and Amsterdam. 
This genus is the type of the tribe Lactucece of M. Cassini. It differs essentially from all other tribes of 
Compositce, in having a divided or ligulate corolla only, and from nearly all other tribes in its style, which can 
be compared to that of Vernoniese only. The radiant head of flowers is a character common both to 
Lactucese and Nassauvieae. The greater part of Lactuces are found in Europe, a smaller number in Asia and 
Africa, very few in America, and in the southern hemisphere none at all. 
1629. Chondrilla. Derived from %av§«o?, a lumi>. Dioscorides says, it bears on its stems little lumps of 
gummy matter. But Theophrastus speaks of the grumous or tubercled roots of his Chondrilla. The plant 
now so called is an inconspicuous perennial plant, of no recorded use.
