Pyaidanthera would make a charming rock-plant: the rose-coloured buds are as pretty nestling among the copious 
foliac^e, as the fully expanded white flowers. A small, tufted, procumbent, creepmg, and wide-spreading shrub, having a 
lonff tep-root in the centre of the tuft : branches terete, slender, younger ones woolly. Leaves alternate cuneato-oblong 
very acute, almost aristate, the young ones woolly at their base within, and hence the specific name of » harbulata. That 
character disappears in the older portions of tlie plant Flowers solitary sessile, from little branches with rosulate leaves. 
Calyx of five, concave, reddish sepals, as long as the tube of the corolla. Corolla monopetalous, white : tube short : 
limb of five, rounded-cuneate, spreading, slightly crenated lobes. Stamens in the sinuses of the corolla. Filaments 
broad, white, almost petalloid, bearing a drooping yellow anther of two almost globose lobes, opening transversely, and 
bearing an a^-n on the lower valve. Ovary ovate, with a tliickened ring at the base, three-celled, few-seeded (four or 
five in each cell) attached to a central placenta. Style as long as the tube of the corolla. Stigma of three small 
spreading rays We have several times received from the United States flowering tufts of this very small shrub; but 
although they have been placed under different kinds of treatment, both in the open air and under protection, we have 
not yet succeeded in keeping them long alive. Dr. Asa Gray informs us that the shrub grows in the warm « pine-barrens 
of New Jersey, in low but not wet places, generally on little knolls, fully exposed to the sun, in a soil of pure sand mixed 
with vegetable mould. We have examined the soil 
in which it grows, which we find no difficulty in imi- 
tating, and by attention the proper degree of moisture 
and temperature can be maintained; but as it has not 
thriven under our care, we infer that the want of suc- 
cess is owing to some peculiarity in its nature, together 
with the difference between the climate of this coun- 
try and that of its native locality. One thing to be 
noticed is that our imported plants have certainly 
been very old, having (comparatively) long wiry roots 
Hke the old roots of a heath. It is probable that our 
cultivation might meet with better success if young 
plants could be procured, either from cuttings or from 
seeds. — Bot. Mag., t 4592.

A handsome Lidian epiphjie, with rich 
orange-coloured flowers and rough steins. 
Tlowers in June. Introduced by the Honour- 
able the East India Company. (Fig. 175.) 
When Dr. Wallich's vast accumulation of botani- 
cal records was, by the great and wise liberality of 
the East India Company, dispersed through all civil- 
ised lands, this plant was a mere fragment, without 
any one thing to show that it was a Dendrobe at all, 
beyond its peculiar habit Recently (May, 1851) 
Mr. Loddiges has produced it in flower; and we are
