and peat soil to grow in. It is easily increased by dividing the old plants when in a dormant 
state, or by seeds, which should be sown, directly they are ripe, in pans filled with light rich soil."

Indigo'fera Do'sua. Referred by Mr. Bentham to the Indian species of the above name, 
although differing materially in appearance. It is said, however, to be exceedingly variable in 
character. The plant is " very pretty when in flower, forming a struggling bush, whose bright 
deep rose-coloured blossoms are highly ornamental. It has been raised in the garden of the 
Horticultural Society from seeds sent to England by Dr. Falconer from the Botanical Garden of 
Saharunpur, and presented by the Honourable Court of Directors of the East India Company. 
It flowered for the first time in May, 1 840 ; but subsequently it has produced blossoms occa- 
sionally through the summer. What gives it its chief value, is that it appears to be a shrub 
sufficiently hardy to stand an ordinary winter in the open border, and growing vigorously in any 
good rich garden soil. It flowers freely during the months of July and August in the open 
border, but earlier if kept in the greenhouse. It is easily increased from cuttings of the young 
wood, treated in the ordinary way, or by seeds." Bot. Beg. 57. 
Mammilla' RiA pycnaca'ntha. " From the collection in the Royal Gardens of Kew : a native, 
it is said, of the neighbourhood of Oaxaca, Mexico. The plant, figured by Lehmann, represents 
a young plant, more elongated than usual. In other respects, it quite accords with our specimens. 
When well grown, the form is almost globose. It flowers copiously, in July, from the summit, 
and numerous off'sets are produced also from the apex, by which the plant may be easily 
increased." The flowers are five or six in number, " opening at a time, on the top of the plant, 
and making a handsome appearance when spreading under the influence of the sun ; of a deep 
sulphur-yellow colour, two and a half or three inches in diameter." Bot. Mag. 3972. 
Sta'tice monope'tala ; var. denuda'ta. The ^S*. monopetala is an interesting evergreen 
shrub, and " that now before us is a well-marked variety, but nothing more, having smaller and 
paler flowers, a more * drawn up ' manner of growth, broader leaves, somewhat wavy at the edge, 
and a much smaller quantity of calcareous scurf. No trace of it is found in books, and it is pro- 
bably of garden origin. The Horticultural Society received it from the Botanic Garden of 
Leyden under the erroneous name of .S*. suffruticosa. It is nearly hardy, requiring only a slight 
protection during winter, when planted in the open border, but it suffers from damp. It flowers 
during the autumn months, and grows freely in any rich light soil, and is easily increased by 
cuttings of the young wood, treated in the ordinary way." The blossoms are light pinkish-purple.

Ste^lis atropurpu'rea. " This new Stelis was sent by Mr. Parkinson from Mexico, to his 
Grace the late Duke of Bedford, and it flowered in the orchidaceous house of that nobleman at 
Woburn, in February, 1839. It has little beauty to recommend it in comparison with many of 
this family of plants, which are such universal favourites." The flowers are borne on a long 
half-drooping spike, and are of a dark blood colour. They are small, but showy. Bot.

As the heat of the sun has now ceased to be felt with any power, and evaporation is carried 
forward with extreme slowness, all plants under artificial culture will require to be cautiously 
supplied with moisture, according to the season. Evaporation is the only sure test of the amount 
of water requisite for plants in pots ; and when that is almost at a stand-still, it is certain that 
very little water can be needed. 
There is another reason, however, why plants should have scarcely any fluid furnished to 
them at this period, and that is that they have now no young wood to nourish and develop. 
When growing, they demand a double supply of nourishment ; but while dormant, their necessities 
are of the most limited desci'iption. And to give them food which they do not need, is a very 
ready way of inducing disease, or bringing them into a generally unhealthy condition.
