Wales, by a number of persons; and were raised, the same year, by most
of those who sowed the seeds. The character of the plant from whence it
derives its specific title is much lost in its advanced state; but in
the first two or three years of its growth, it is extremely powerful;
the under part of the young leaves being of a bright purple. It is
extremely difficult to propagate from cuttings; and it has not, as yet,
perfected its seeds in England. It grows to the height of six or seven
feet; is a hardy green-house plant; and thrives most in sandy peat
earth. Our figure was made from a very fine specimen, communicated by
the Hon. W. H. Irby, in September 1801, from his elegant collection at
the Parsonage, Farnham Royal, near Windsor, Bucks.

This most brilliant variety of Hypoxis stellata, is as old an inhabitant
of our gardens as the other Var. figured in the 2d Vol. of the
Repository, Pl. 101; it was likewise introduced by Mr. F. Masson. The
roots of this plant are rather more tender, or delicate, than those of
the yellow variety; which makes it scarcer, and much less known. The
nursery, Hammersmith, is the only place at which we have seen it; and,
we believe, they have it not in Holland. The root from which our figure
was taken, had been imported, from the Cape, in 1801. It flowers in
April, and increases by the root; should be planted in very light sandy
peat earth, and removed from the pot soon after the flowers are
decayed.

This pretty Cytisus, a native of the Cape of Good Hope, was raised from
seeds at the Hammersmith nursery, in the year 1798. It is rather a weak,
and loose growing shrub, attaining the height of a foot and a half, and
flowering about August. It delights in a light soil, and is propagated
with ease by cuttings; it likewise perfects its seeds. The whole habit
of the plant much more resembles Crotolaria than Cytisus; but the
seed-vessel and empalement preclude its admission to that Genus.

As an annual, this is a most beautiful little plant; but, although the
seeds have been received several times, from the Cape of Good Hope,
where it is native; and first at the Royal Gardens, Kew, in 1787, sent
by Mr. F. Masson; yet, has it never been seen the second year; owing, we
suppose, to the impracticability of procuring ripe seeds in our climate.
Perhaps future trials, by different treatment, may meet with a happier
issue. The figure was taken at the Clapham Garden, in August 1800; when
the plant had apparently attained its greatest perfection; but
unfortunately, no seeds ripened; and at present, we believe, there is no
vestige of the plant in Britain. It appears to delight in sandy peat,
and to be kept under cover, even in the summer season.

Geranium selinum claims the priority of introduction, with us, to any of
that numerous division, in this large family, which are tuberous rooted
and stemless, not including the G. triste, G. lobatum, or G. prolificum;
and of which, although we have given many figures, we still possess
drawings of 18 handsome species, besides numberless varieties. It was
introduced in 1788 by Messrs. Lee and Kennedy; is a hardy greenhouse
plant, being less subject to rot, after the decay of the leaves, than
any of its congeners; flowers freely about June, and is propagated by
the root; the seed (sometimes) ripens likewise. Our figure was taken
from a plant, whose root had been received at the Clapham Garden, in
1800. As all the plants figured in the Botanist’s Repository, are titled
with the commonly accepted names, if any, in England; and, as many have
been given under different names, in some other publications, whence
much confusion; we shall defer all attempt at synonim, till the end of
this Volume, when a copious _Index Synonimorum_ will be published, of
all the plants figured in the work, for the use of those who wish for
such authorities.

Our present plant has a nigh affinity with G. communis, and indeed
might, perhaps, be considered as a variety of it; but, as upon a close
examination this will be found to differ, in many respects, we have
adopted the name, quoted by Willdenow, from Jacquin, De la Roche,
Burman, &c. It is a native of the Cape of Good Hope, and introduced,
from thence, to us, in 1800. Our figure was made at the Hammersmith
Nursery, this year, being the first of its flowering in this country. It
is a very hardy bulb, and increases freely. Flowers in May.

As a singularity among its fellows, this Gladiolus stands prominently
distinct; and the uncommon and curious formation of its flowers will,
undoubtedly, counterbalance, in the eye of the botanist, what they want
in brilliancy of colour. It is a hardy bulb, and appears to require only
the usual treatment of the hardier species of the genus. The Clapham
collection is, we believe, the only one in which it is to be found in
England; to which it was introduced, by Mr. Niven, in the spring of the
year 1801, and where our drawing was made, this present year, in the
month of March 1802.

4. The Pointal of a female floret, magnified.
Amongst the number of very beautiful plants introduced by Mr. Niven, and
which now enrich that fund of botanical rarity, the Clapham collection,
this species of Xeranthemum does not stand the least conspicuous. Twelve
years since we possessed but four species of this genus, viz. X.
fulgidum, X. retortum, X. vestitum, and X. speciocissimum; now they
extend to fourteen. The others, as well as the foregoing, are all (but
one, the X. lucidum of Port Jackson, New South Wales) from the Cape of
Good Hope, and introduced to us from thence, by various hands, in the
following order; X. proliferum, through Holland, by Messrs. Lee and
Kennedy; X. formosum and X. candicans by the same, from Cape seeds; X.
sessamoides by Mrs. Gostling, of Hounslow; X. filiforme by Mr. Dunn, of
Cambridge; X. fasciculatum and X. truncatum by G. Hibbert, Esq. X.
argenteum and X. spirale by Montague Burgoyne, Esq. of Mark Hall, Essex.
They are very subject to damp in the leaves, from a confined air
therefore, should be kept in the window, or most airy part of the
greenhouse. The most sandy peat that can be procured is the best for
their growth. They may be all, thus, propagated by cuttings, taken off
in the early part of the month of June; put these into a pot filled with
sand, and covered by a bell-glass the size of the pot; plunge it in a
north or east border, and let the whole be covered with a hand glass,
which must be kept quite close till the cuttings are rooted; then the
inner glass must be removed, and in about a week the pot maybe taken
from under the outer one, when the plants may be removed into small pots
in about a fortnight. Our present plant seldom grows higher than two
feet, of which, at least, one is the foot-stalks of the flowers; it
continues in flower from March till September.

This handsome Protea we owe to Mr. R. Williams, of Turnham-green,
nurseryman, who raised it by seeds received from the Cape of Good Hope
in the year 1797. It is one of the handsomest we yet possess of the
winged-leaved kind of Proteas; of which division, in this large family,
there are now in the Hibbertian collection eighteen distinct species.
This plant grows to the height of three feet, makes a very bushy head,
and, when in flower, has a handsome appearance; as there are sometimes
twenty spikes of flowers on it at one time. It is propagated by
cuttings, thrives in sandy loam, and flowers in June; in which month
this year, 1802, our drawing was made at Clapham.

3. The Pointal and Seed-bud, cleared of the chives.
We have little doubt but that this is the species of Day-Lily known to
botanists, since the days of Parkinson and Gerarde, under the character
of a small leaved variety of the Yellow Day-Lily, although it has been
many years lost to the country. It is one amongst the many plants
introduced by the late Dr. Sibthorpe, to the Oxford botanic garden. As a
native of the northern parts of Europe, it is as hardy as either the H.
flava or H. fulva, to both which species it bears strong affinity;
although, we conceive, sufficiently distinct from either, to constitute
a species; which however we should not have done, but that the plant is
now known in our gardens, under our specific title. The flowers of this
plant last, in general, two or three days before they decay, are very
sweet scented, and as large as those of the H. fulva. It is increased as
easily as any of the genus, by parting the roots, and thrives in almost
any soil.

2. A Flower cut open, with the Chives in their place.
3. The Pointal, one of the summits detached and magnified.
This pretty little Ixia is quite new to our gardens, never having, as
far as we can learn, been seen to flower before this year. It is the
most delicate in shape and character of any we have as yet examined; and
as we could not trace it as described in any author, we have given it
the trivial name it here bears. The figure exhibits a large specimen of
the whole plant, which is too weak to support itself, although the
leaves are thick and stiff. Our drawing was made in the month of April,
from a plant in the Clapham collection, where only it is to be found;
the roots having been sent from the Cape of Good Hope in the autumn of
the preceding year. It appears to flourish with the treatment Mr. Allen
has given it, a dry situation, planted in very sandy peat. From the
construction of the root, which has a hard smooth skin, we should be led
to think its increase will not be very abundant.

Our figure, which exhibits a small plant, of this superb species of
tuberous Geranium, was taken in the month of June, this year, 1802, at
Messrs. Colville’s nursery, King’s Road, Chelsea, and where it is still
in high perfection, this present month of July. We have every reason to
believe, from all the authorities we are masters of, that this plant has
not, till now, flowered in Europe. It forms a very large tuberous root,
by the dividing of which it is to be propagated; as we suspect the seeds
will not ripen on this species more than most of its congeners. It has
the same manner with the rest of the tuberous species, losing its leaves
in winter, when they are subject to rot, if much watered. Appears to
flourish in sandy peat, with a small portion of rotten dung.

The singular shape and number of the leaves of this plant, which are but

at the edge, constitute the most essential specific difference it
possesses; the flowers, and other parts, much resemble many of its
fellows. It is from the Cape of Good Hope, and introduced to us by
Messrs. Colvills, nurserymen, of the King’s Road, Chelsea; who received
it, from thence, at the same time with the Geranium incrassatum, of our
last. For the treatment, and increase, we must refer to any other of the
tuberous kind of Geranium.
