Ericas; Ericas -- Pictorial works
LEAVES grow mostly by fours, oblong, sawed, clothed with long hairs,
smooth on the upper, and furrowed on the under part, having very short
leaf-stems pressed to the branches.
FLOWERS are numerous, in single whorls, near the summit of the branches,
bending downward, and spreading, the foot-stalks hairy, with three small
leaves fixed on their under part.
EMPALEMENT. Cup four-leaved, which are lance-shaped, hairy, pressed to
the blossom, and rolled back at the point.
BLOSSOM nearly cylindrical, shining, clammy, and most beautifully
coloured with red, yellow, and green, narrow at the mouth, which is
divided into four segments.
CHIVES. Eight hair-like threads, the length of the blossom, fixed into
the receptacle. Tips beardless.
POINTAL. Seed-vessel club-shaped, and furrowed. Shaft thread-shaped,
rather without the blossom. Summit four-cornered.
Native of the Cape of Good Hope.
Flowers from August till December.
