a native of Transylvania, and in tin’s country is one of the 
earliest to flower in spring. Similar treatment should he given 
it as in the case of A. carnea. When seeds are matured the 
f'ult ivator should take this means of rearing it. Reserve 
plants are always valuable,- and a careful plantsman can 
manage it in pots when for some reason or other it might fail 
on the rockery. Pot plants can always be moved so as to 
avoid the fierce glare of the sun in summer. Plants can thus 
be reared in cold frames to make good any loss that may occur 
in the collection. Cuttings also may be easily rooted in pots 
of sandy soil placed in a cold frame facing the north during 
summer, and shaded till roots are formed. 
A. brigantiaca. 
Peep green leaves and white flowers are characteristic of this 
pii 1 1 y low growing species, which enjoys a fairly wide diatribe 
tion on Continental Europe. It should he planted where the 
mots can penetrate pretty deeply between stones, which assist 
in keeping the roots cool in summer and di-y in winter by per¬ 
fect drainage. There is no question about the hardiness of 
these European species, but the open and moist character of 
our winter is different from the cool and dry conditions which 
keep these plants at rest in winter. 
A. villosa. 
As the name would imply, the foliage of this species is of a 
woolly nature, recalling the general appearance of Cerastium 
alpinum vdlosum, though the individual leaves are smaller and 
different in shape. The umbels of flowers are white, though 
liable to variation in this respect, like many other subjects of 
geological antiquity which are found over a large area of the 
globe. It has been collected in various places extending be¬ 
tween South-Western Europe and the Himalayas. The flowers 
vary from white to pink, while the plants also differ in vigour 
in different regions. Cultivation is as easy as any of the above, 
provided some little care is taken to protect the foliage against 
snow and rain in winter. This can easily be done by fixing 
a pane of glass over it by means of pegs in such a way as to 
allow a free play of air at the sides. The covering may simply 
remain till growth recommences in spring. 
A. v. Chamaejasme has been applied to a strong growing 
variety, also dignified with the name of Rock Jasmine. The 
flowers vary in the intensity of colour to a greater extent than 
the typical plant to which it is subservient. Although it likes 
to be kept dry overhead in winter, it delights in a constant 
supply of moisture in summer like other mountain plants. 
Where the rock garden is of any extent, this watering should 
be done with the hose attached to a stand-pipe from which a 
plentiful supply can be obtained, otherwise the watering would 
have to be confined to those subjects which specially require it. 
A. helvetica. 
In this instance the flowers are produced singly from the 
rosettes of leaves like its not very distant relation Primula 
minima. The size of the bloom compensates for the lack of 
numbers, though the density of the cushion of leaves brings the 
flowers close together, so that a patch in spring is really hand¬ 
some. The small leaves are very hairy, so that the whole mass 
resembles a cushion of moss set over with white flowers. A 
shady, cool situation should be selected for it between stones 
of a porous character likely to retain the moisture. In some 
districts an oolitic and porous kind of limestone is readily 
obtainable, and if employed in building a portion of the rock 
garden would form a cool medium in the crevices of which 
plants of this and a similar character might be grown success¬ 
fully. The roots would also be well drained in winter. It 
was one of the earliest introductions, being in cultivation in 
1775. 
A. alpina. 
The leaves of the alpine Androsace are also produced in 
small rosettes, producing in the aggregate a close cushion, one 
flower from each in early summer. The flowers are rose-' 
coloured with a yellow eye, and make their appearance in .Tune. 
The species was introduced in the same year as A. helvetica, 
hut is rather difficult to cultivate successfully, and has 
doubtless been re-introduced several times from its native 
habitats. A peaty soil selves to keep it cool, while that of a 
loamy character would lie likely to get hot and hiked, which 
would mean ruin to the plant. Shade from the sun after ten 
in the morning would also be of material advantage to it. 
A. glacialis. 
bike the last, this conies from high elevations, hut provid'-d 
the plant is kept cool in southern latitudes it may be "town 
in full exposure, as light is the life of it. The white or rosy 
flowers appear early in spring, like many others from similar 
elevations which prepare for flowering during the previous 
season. Freestone grit may be freely used in the soil in which it 
is grown, and stones of that character or of a schistose nature 
will afford conditions that will enable it to pass through the 
heat of summer. Some books regard this as being identical 
with A. alpina, but though a certain similarity prevails in out¬ 
ward fonn, their likings are different. 
A. lanuginosa. 
Several of the Himalayan species are markedly different in 
habit from their European relatives, but this applies to habit, 
stems and foliage more than to the flowers. Planted out in a 
sunny spot on the rockery, this makes a liberal growth during 
the summer, the slender stems elongating and falling over the 
ledges more after the manner of a lowland plant. The silvery 
leaves, being covered with silky hairs, resemble those of a 
Mouse-ear Chickweed (Cerastium) more than any of the above 
species. Neither is it so particular in the matter of soil, pro¬ 
vided it is of an open or friable nature and well drained, espe¬ 
cially in winter. The silky leaves dislike the neighbourhood 
of towns where the atmosphere is filthy in winter owing to the 
presence of soot, which collects upon and is retained by the 
leaves. In such districts it would be greatly benefited by the 
protection of a pane of glass in winter, as recommended for 
A. villosa. It was introduced from the Himalayas in 1842, and 
may be regarded as one of the easiest to cultivate provided the 
above precautions are taken in districts where the conditions 
necessitate the same. Propagation is easily effected by cut¬ 
tings taken from the short side shoots ; and if this is done early 
in July the tops of the rooted cuttings may also be taken off 
and rooted as soon as long enough to be removed without de¬ 
priving the first one too much of foliage. Provided this addi¬ 
tional batch is not required, the rooted cuttings should be 
potted off singly to encourage branching, and a fine lot of 
plants will be in readiness for planting out- in spring. 
The variety named A. 1. Leichtlinii has rather darker flowers 
with a yellow eye that changes to red. The blooms are also 
said to be larger, but it seems largely a matter of cultivation. 
A. sarmentosa. 
The special feature of this Himalayan species is the 
numerous runners that each crown produces when planted out 
on the rockery in rich, friable, and well-drained soil. Each 
crown may be said to consist of a rosette of spathulate, hairy, 
or shaggy leaves lying close to the ground. The runners give 
rise to other rosettes that soon stud the ground all round the 
mother plant, forming a large patch in a single season. Small 
pieces of sandstone laid round the mother plant and between 
the rosettes of the offspring will keep the ground moist and 
cool. Some protection must also be given the silky leaves in 
winter to protect them from filth and moisture. A pane of 
glass will answer the purpose, for though a projecting ledge 
of rock is often recommended, this lias the effect of throwing 
off the rain in summer which is beneficial to the foliage and 
plant alike. The flowers are rosy-purple and produced in 
umbels of fifteen to twenty on short scapes from the rosettes. 
The offsets may be separated as soon as rooted to form other 
colonies, or allowed to form a broad patch so long as there is 
room. 
A beautiful plant that made its appearance quite recently in 
cultivation, and named A. Chumbyi, is now considered to be a 
hybrid between A. sarmentosa and villosa, having runners like 
the first named, proceeding from the rosettes of leaves, and 
richer purple flowers with a dark red eye. 
A. foliosa. . 
The rosy-red flowers of this species are produced in succes¬ 
sion from May to September, in large umbels, on plants similar 
in habit to A. lanuginosa, but of greater vigour. It may be
