104 THE LADIES' FLOWER-GARDEN 
Tlie seeds of the Calandrinia discolor of the London gardens are generally sown in March, on a hotbed, potted 
off when they come up into small pots, and afterwards transplanted into the open border in May ; or the seeds 
may be sown in the open border in May, the only difference being that the first-sown plants will flower earlier, 
though so little as scarcely to be worth the trouble of transplanting, &c. This species requires a rich calcareous soil, 
and an open sunny situation. We sowed some seeds obtained from Mr. Charlwood, in May 1838, in the open 
ground, in a warm border, sheltered by a wall ; and the plants grew luxuriantly, being from a foot and a half to 
two feet high. The flowers began to expand in July, and in August we had a most brilliant display, which con- 
tinued till the first frost, which, though a very slight one, destroyed the Calandrinias completely in a single night. 
When young, the Calandrinias are also liable to be killed by the slightest frost ; and for this reason, in gardens 
where there is but little shelter, it is always safest to raise the plants on a hotbed. 
OTHER SPECIES. 
These are very numerous ; but we believe that no others have been as yet introduced that can be treated 
as annuals. 
- GENUS II. 
CLAYTONIA, Lin. THE CLAYTONIA. 
Lin. Syst. PENTANDRIA MONOGYNIA. 
GiHiRic CBAnACTER..— Sepals 2, permanent. Petals 6, unguiculatcd ; claws connate at the base. Stamens S. Style 1, trifid at the apex. 
Lobes stigmatose inside. Capsules 3-valved, 3-seeded. — (G. Don.) 
Description, &c. — Succulent plants with small flowers, usually white or rose-coloured ; which, as they are 
certainly not worth cultivating for their beauty, we shall only say a few words of, without entering into details. 
1.— CLAYTONIA PERFOLIATA, Don. Bot. Mag. t. 1336. 
. This species was discovered on the North-west coast of North America, by Archibald Menzies, Esq., and 
sent by him to the Kew Gardens, in 1796. The flowers are white, and very small ; and the leaves, which are 
rather short and broad, are eatable, like those of the common Purslane. 
2.— C. ALSINOIDES, Sims, Bot. Mag. t. 1309. 
This species resembles the common Chickweed, except in its succulent leaves. A native of North America, 
introduced in 1794. 
3. — C. SIBIRICA, Sims, Bot. Mag. t. 2243 ; Sweet, Brit. Flow. Card. t. 16. C. ALSINOIDES, var. ROSEA, Dec. 
A dwarf plant, not growing above six inches high, with pink flowers ; very suitable for rockwork. A 
native of Nootka Sound, and said also to.be found wild in Siberia. Introduced in 1820, and worth cultivating. 
4.— C. GYPSOPHILOIDES Fisch. et Mey. ; Brit. Flow. Card. 2nd Ser. t. 375. 
A native of the Russian colony of Ross, in California, whence seeds were first sent to St. Petersburg, and 
thence, in 1837, to England. It is low-growing, with a great number of grass-like stems, and a profusion of 
very small bright pink flowers. All the Claylonias require a dry sandy soil, and the last two are worth culti- 
vating for rockwork.
