DISCARIA LONGISPINA.--This is at once a curious and beautiful shrub, of

low, creeping growth, and poorly furnished with leaves, which, however,

are amply made up for by the deep green of the shoots and stems, and

which give to the plant almost the appearance of an evergreen. The

flowers, which are bell-shaped and white, are almost lavishly produced,

and as they last for a very long time, with only the pure white

assuming a pinky tinge when subjected to excessive sunshine, the value

of the shrub is still further enhanced. For planting against a mound of

rock this scrambling shrub is of value, but the position should not be

exposed to cold winds, for the plant is somewhat tender. From South

America, and allied to the better known Colletias.

D. SERRATIFOLIA (_syn Colletia serratifolia_), is even a handsomer

plant than the former, with minute serrated foliage, and sheets of

small white flowers in June.
