heiranthus alpinus. 
The Alpine Wallflower is a native of Nonvay and Sweden, 
em whence it was first introduced in 1823. Sometimes we 
io> it iii gardens under the name of Erysimum alpinum and E. 
ehroieucum. The last-named is a very procumbent plant, 
awever, not rising much above the rocks on which it grows, 
lie plant under notice grows about a, foot high, with upright 
iufy stems bearing a raceme of large lemon-yellow flowers, 
liich are sweetly scented. 
Being naturally a rock plant like the common. Wallflower, 
lis is admirably adapted for cultivation on the rockery, and 
ill succeed in almost any position, provided it is well exposed 
hi light, and air, which increases its hardiness and sturdiness, 
n the course of a year or two it will make a good-sized patch 
: low persistent stems, from which it develops its flower- 
ierns. In early summer, long after the common Wallflower is 
ut of bloom, this makes a tine display, and lias considerable 
rsemblance to it, except that, the leaves are thinly toothed, 
ud the flowers are lemon-yellow, recalling Lemon Queen, a 
piety of C. Cheiri. 
It does not seed very freely, but all the plants that are 
iecessary may be obtained by taking cuttings in June 
Lnd July and inserting them in pots of sandy soil, plac- 
n'g the same under a handlight or in an unheated frame 
acing the north. - Here they will root in about a fort- 
light, provided the euttingsi were not too hard when 
aken. Care should also be exercised to take cuttings 
rear the base of the plant, neither showing flowers nor 
laving flowered. If put into root thus early, the cut- 
ings often commence to throw out side shoots, and 
Jiese in turn may be used as cuttings if a large stock 
:s desired. Cuttings taken from plants in a closed 
fame will root in half the time of those from the out- 
ide, especially if the weather is at all dry. 
Our illustration shows a plant growing amongst the 
ocks 1 , the stems being borne down by thei wet weather 
lust before the plant came into bloom, so t hat the stems 
lo not appear so high as they really were. 
ilium tenuifolium. 
When, planted out of door’s 1 this is one of the dwarfest 
ind most slender of all the Lilies, the stems flowering, 
dthough only 6 in. to. 12 in. high. In northern gardens 
ve have seen this flower every year, but carrying only 
i solitary bloom at the top of the stem. It is a very 
umdsome, graceful, and dwarf Lily, even under those 
auditions, as it. proves very attractive when a, clump of 
'ailbsi is in. bloom. 
Besides being perfectly hardy and suitable for out- 
lour culture, it also succeeds admirably when potted up 
n autumn and brought on under glass with very little 
r no heat beyond what may be necessary to keep out the 
fast in severei weather. 
Our illustration was prepared from a specimen given us by 
Jessirs. It. Wallace and Co., Kilnfield Gardens, Colchester, 
ibis, of course, had been grown under glass in order to bring 
t on early, and this treatment is certainly favourable to its 
welfare, as the stem was nearly 21, ft. high and carried nine 
dooms. The number of blooms, it. will thus- be seen, depends 
cry largely upon cultural treatment, and the strength of the 
iulbs employed. It has been, known to carry as many as 
wenty flowers, which vary from in, to. 1| in. in length of 
be segments. When fully expanded these segments are rero¬ 
ute, while the flower hangs with the face downwards. This 
vould put it in the Martagon. or Turk’s-cap section of 
nlies, and it is certainly one of the most handsome 
f them, although at the same time one of the moist slender, 
die flowers are of a brilliant orange-scarlet, usually without 
my spots, as in the specimen we tigure, and owing to the 
Inning gloss the flower has a very attractivei and rich appear- 
mce. Under artificial light this colour is equally telling, as 
n daylight. The leaves are very numerous, linear, slender and 
mo-nerved. 
The species was first introduced from Siberia, in 1820, and, 
notwithstanding its distinctness, it has received several names 
by different botanists. In a. wild state, however, it extends 
from the Altai Monntains to Northern. China, including Man¬ 
churia. 
Xanthoceras sorbifolia. 
Although introduced from China in, 1870 (some say 1866), 
this beautiful shrub has not received the attention in this 
country that its merits deserve. In the United States it has 
practically been neglected to a similar extent. For a number 
of years we have heard little or nothing of it in this country, 
except from botanic gardens chiefly. It is quite hardy, in 
England at least, and is well worthy of extended cultivation 
in private gardens for the beauty of its flowers in spring, and 
its finely-divided leaves during the rest of the season. The 
flowers are borne in, dense racemes, terminating almost, every 
shoot of the plant, but, the petals not being spread out, each 
individual only measures about A in. across. The petals are 
white, with a, red zone at the base. These are succeeded by 
fruits which attain the size of small Apples, and contain some 
eatable matter, and are accordingly eaten to some extent by 
the Chinese. The fruit ripens in this country'. The leaves 
are not unlike those of the Mountain Ash, as the specific 
name implies. The generic name is derived from the presence 
of yellow horn-like glands between the petals. Even for the 
foliage alone the shrub would be worthy of cultivation either 
in a shrubbery or on tlie grass. 
The plant may be propagated by seeds,, cuttings,, layers, or 
’root cuttings. Those who succeed in ripening fruits will have 
no difficulty in raising young plants. It, can be more readily 
and as speedily raised by cuttings of the root cut into pieces 
about 1 in. long and inserted in pots of sandy soil in a pro¬ 
pagating pit. As these roots; are somewhat fleshy they may 
be allowed to diy somewhat, before inserting them. 
The plant is a member of the same family as the Horse 
Chestnuts, Buckeyes, and Maples. Besides its use as an out¬ 
door ornament, it, may also, be grown in pots for conservatory 
decoration during March and April. The specimen from 
which our illustration was prepared was so grown by Messrs. 
James Yeitoh and Sons', Limited, Chelsea,, who exhibited a 
large group of it in 8-in. or 10-in. pots, producing a, splendid 
effect at one of the Drill Hall meetings of the II.H.S. 
An Enthusiastic Orchid Collector.— The “ South American 
Journal ” says that, Signor Barbasa Rodrigues, director of the 
Botanic Gardens at Rio de Janeiro, has discovered no less than 
500 new species of Orchids.
