DESCRIPTIVE LIST OF NEW PLANTS. 
using sandy peat with a small portion of loam, place it in a moist 
temperature in bottom heat, so as it may grow away freely, 75° 
will be sufficient for it; towards summer it should be hardened 
by degrees to endure the temperature of the greenhouse, and in 
autumn it should be placed in rather a cool stove, where it will 
continue flowering for some months. The plant is as yet scarce 
in this country, it is not, however, difficult to propagate, as it will 
strike readily by cuttings in heat under a hand-glass.— Bot. Beg. 
12-46. 
Asteracejs, or Composites. —Syngesia Polygamia. 
Mulgedium macrorhizon. This, although its flowers are but 
those of Succory, is nevertheless a charming perennial, with 
numerous trailing stems, two feet long, and scarcely rising more 
than a few inches high. For decorating rock-works it is unsur¬ 
passable among autumnal perennials. It grows willingly in a 
soil composed of sand peat and loam, and is hardy enough to 
stand the winter in the open border, but its large fleshy roots 
render it impatient of moisture and it is frequently destroyed in 
winter by damp. It should not only he planted in a very dry 
situation, but protected either by a hand-glass or dry leaves. It 
is easily increased by seed sown in pots and placed in a cold 
frame. It flowers in September and October, and remains for a 
long time in perfection; trailing over stones or rocks and covering 
them with a carpet of lively blue. It was raised in the garden of 
the Horticultural Society from seeds received from Dr. Eoyle, 
and stated to have been collected in Cashmere or Thibet.— Bot. 
Reg. 17-46. 
Archidace^e. —Gynandria Monandria. 
Dendrobium aduncum. Of this very pretty orchid we know 
nothing more than that it was sent from Calcutta to Messrs. 
Loddiges by Dr. Wallich, and that it flowered at Hackney in July, 
1843. In some respects it is allied to D. Pierardi, especially in 
its small pink flowers and manner of growth; but it is more 
closely related to D. moschatum, of which it may be regarded as 
a feeble imitation. It is, however, widely different from both, 
and especially known by its half transparent flowers of the most 
delicate texture and clearest tints. Why it is called D. aduncum, 
or whence it comes, we know not.— Bot. Reg. 15-46.
