LETTSOMIA (named in hononr of J. C. Lettsom, 
a British physician and naturalist). Orb. Convolvulacex. 
A genus embracing upwards of thirty species of climbing, 
more or less hairy, stove shrubs, natives of Eastern Asia 
and tropical Africa. Corolla tubnlar-funnel-shaped ; 
stamens included or exserted: cymes axillary, pedun- 
culate, densely corymbose or capitate, bracteate. Leaves 
alternate, undivided, often rounded or cordate at base. 
Only one species calls for mention here—that described in 
Vol. I. as Argyreia capitata. For culture, see Argyreia. 
LETTSOMIA (of Ruiz and Payon). Included under 
Freziera (which see). 
LETTUCE. On hot, dry soils, where Lettnuces are 
so liable to ‘‘bolt”’ during the summer, without forming 
hearts, it is a good plan to sow the seed thinly in drills, 
and thin out the plants to proper distances apart as 
soon as they are large enough to handle, at the same 
time keeping them well watered. By this means no 
check is given, as in the case of transplanted Lettuces, 
and they quickly form good, tender hearts. In many 
gardens it is almost impossible to get good Lettnuces in 
hot, dry weather without adopting this method of 
sowing the seed, and not transplanting. 
Sorts. To the varieties named in Vol. II., the following 
may be added as especially good. 
Cabbage Lettuces. *DANIELS’ ConTINUITY, heads medium, 
solid, leaves thick and edged with red, very crisp and tender ; 
withstands hot weather better than any other variety. 
*GOLDEN YELLOW, heads large, solid, crisp, and of good flavour ; 
an excellent variety for summer use. PERFECT GEM, heads 
medium, solid, tender, and fine flavour; a good, dark green 
variety, withstanding drought well. 
Cos Lettuces. *CHAMPION WHITE, heads very large, whitish- 
green, firm, and sweet; a very good summer variety. 
*LEVIATHAN, a larger and improved form of the old Brown or 
Bath Cos; *LONDON WHITE, heads large, quickly developed, 
firm, and of good flavour; much esteemed by market growers. 
LETTUCE APHIS (Siphonophora 
Lettuce—Insects, Vol. II. 
LETTUCE MILDEW (Peronospora ganglioniformis). 
Little can be added of practical value to the information 
contained in Vol. II, Though the name above adopted is 
the one generally applied to the disease, yet the fungus 
is not restricted to the Lettuce, but is found upon 
Cinerarias, Sonchus, Artichokes, &c. Whole houses of 
Lettuce are sometimes affected by the disease in winter, 
and when this is the case care should be taken not to 
utilise such structures another season for a similar crop. 
A more recent scientific name for the Lettuce Mildew is 
Bremia lactuce.
