LATACE (name not explained by its author). Orn. 
Inliacez. A monotypic genus. The species is a green-

LATANTA. 
genus. 
LATENT. Remaining dormant; e.g., Latent Buds. 
LATERALS. A term applied by gardeners to the 
side shoots springing from a stem or branch. For 
instance, those shoots on Vines which emanate from the 
spurs caused by pruning are Laterals, and any shoots 
starting from the Laterals are sub-Laterals. Again, the 
shoots emanating from strong growths of the current 
year’s growth are Laterals, as frequently seen in Peaches, 
Nectarines, and Plums, and large trees are quickly formed 
by “‘laying-in” all the Laterals which grow in a suitable 
direction on young wall-trees. 
LATHRZA. Including Clandestina. To the species 
described on p. 237, Vol. II., the following should be 
added : 
L. Clandestina (Clandestina).* . pale _greyish-purple or 
violet, with a dark purple lower lip, erect, 2in. long; racemes 
3in. to 5in. high, many-flowered. April. Stems innumerable, 
densely crowded, nearly buried in the earth, 4in. to 6in. high ; 
scales jin. to fin. broad. Rhizomes densely interlaced. Europe, 
1888. A very handsome perennial. (B. M. 7106.) 
LATHYRUS. Including Clymenum. So important 
has the culture of the Sweet Pea become, alike as a 
pot-plant for the greenhouse and as a decorative and 
a market plant outside, that some fuller information 
than is given in Vol. II. is called for. First, it may 
be considered as a hardy annual than which there is 
nothing finer. In the garden of the average amatenr, 
the Sweet Pea receives but scant attention, and its 
period of beauty is naturally very restricted; but 
where it is cultivated as it shonld be, the flowering 
season may be prolonged to almost any extent. 
To start with, the soil must be rich, and if this is not 
so naturally, it must be made so by the incorporation of 
thoroughly rotten manure, dug in, say, the previous 
autumn, and then allowed to remain open to frost and 
air until the time for sowing the seeds comes round. 
This is usually some time in early spring, choosing a day 
when the soil is in working order, and breaking it up 
roughly. To prevent the seeds when sown from being 
taken by birds and mice, it is usual to soak them for a 
quarter-of-an-hour in paraffin, or else to coat them with 
red-lead. The seed may either be sown in rows some 
6ft. or 8ft. apart, to form a hedge, or in colour-groups, 
using a large inverted pot and sowing the seed round the 
impression made by the rim, keeping the seed, in the latter 
case, a good distance apart. In large gardens it is usual 
to make sowings in March, April, and May in drills drawn 
about 3in. deep, and to protect the quarters with black 
cotton arranged diagonally. 
As soon as the seedlings are an inch or two ont of the 
soil, they should be firmly staked, using sticks containing 
all the twiggy growths, and the soil at each side made 
firm. It is rar advisable to use a light mulching, as 
this prevents the moisture in the soil from evaporating
