282 GREEN-HOUSE — OP REPOTTING. [ October. 
collections, flowers rosy purple, in terminal heads, and late- 
ral bunches in great profusion ; blooms from January to 
May, and is of a peculiar fragrance. D. oleoides is what 
maybe termed "ever-blooming:" flowers of a lilac colour; 
leaves elliptic, lanceolate, smooth. D. laureola, Spurge lau- 
rel; D. pdntica, D. alpina, and D. Cncdrttm, are all fine 
species, and in Europe are esteemed ornaments in the shrub- 
bery, but they are not hardy in our vicinity. (Soil No. 15.) 
Primula. There are a few fine species and varieties in 
this genus, adapted either for the green-house or rooms. All 
the species and varieties will keep perfectly well in a frame, 
except the China sorts. Having previously observed a few 
of the other species and varieties, we will observe the treat- 
ment of these. P. sinensis, now prsenitens, known commonly 
as China primrose; flowers pink, and in large proliferous 
umbels, flowering almost through the whole }'ear, but most 
profusely from January to May. There is a double white 
and a double purple variety that will always be scarce, from 
the slow method of their propagation. Keep them in the 
shade, and be careful that they are not over-watered during 
summer. As the stems of the plant become naked, at this 
repotting a few inches should be taken off the bottom of the 
ball, and placing them in a larger pot will allow the stems 
to be covered up to the leaves. P. p. albijiora, colour pure 
white and beautiful. P. p. Jcntijiora ; there is also a 
white variety of this, both similar to the former two, only the 
flower indented or fringed. All these require the same treat- 
ment. As they live only a few years, many individuals, to 
propagate them, divide the stems, which in most cases will 
utterly destroy them. The best, and we may say the only 
method to increase them is from seed, which the}- produce 
every year. (Soil No. 2.) 
Psednio mdutcot : this magnificent plant and its varieties 
are quite hardy with us, but most of them require the green- 
house in northern latitudes. These are P. moutan, Tree 
Paxmy; the flower is about five inches in diameter, of a 
blush colour, and semi-double. P. M. Banksii, is the common 
Tree P;rony, and called in our collection P. moutan ; it has 
a very large double blush flower, and is much admired. P. 
M. papaveracea is a most magnificent variety; has large 
single white flowers, with purple centres. P. M. rosea is a 
splendid rose-coloured double variety, and is scarce; there arc
