CALLU'NA* * 
Linnean Class and Order. Octa^vdria f, Monogy'nia. 
Natural Order. Eri'cete, Dr. R. Brown. — Lind. Syn. p. 172 ; 
Introd. to Nat. Syst. p. 182; Loud. Hort. Brit. p. 523 . — Eri'c^e, 
Juss. Gen. PI. p. 159.; Sm. Gram, of Bot. p. 115 . — Erici'nea?, 
Rich. by. Macgilliv. p. 450. 
Gen. Ciiar. Calyx (fig. 4.) inferior, permanent, double ; outer- 
most of 4 oblong, blunt, fringed leaves ; inner of 4 elliptic-spear- 
shaped, concave, coloured, polished sepals, concealing the corolla. 
Corolla (fig. 3.) of one petal, bell-shaped, deeply 4-cleft, upright, 
much shorter than the inner calyx. Filaments 8, (figs. 5. and 6.) 
from the receptacle, short, curved. Anthers terminal, upright, 
spear-shaped, with 2 lateral oblong orifices, each united before 
bursting, with the similar orifice of its neighbour at each side ; the 
base bearing 2 deflexed bristles. Germen superior, roundish, de- 
pressed. Style (fig. 7.) cylindrical, nearly upright, the length of 
the inner calyx. Stigma capitate (knobbed) , with 4 notches. Cap- 
sule concealed by the indexed, permanent, inner calyx, round, a 
little depressed, with 4 furrows, 4 simple valves, and 4 cells ; the 
partitions simple, flat, alternate, and unconnected with the valves, 
fixed vertically to a large, egg-shaped, pitted, permanent, central 
column. Seeds numerous, small elliptic-oblong, attached to the 
column. 
Differs from Erica in having a double calyx, and in the dissepi- 
ments (partitions) being attached to the column, and opposite to 
the margins of the valves. It may be distinguished from other Ge- 
nera, in the same class and order, by the monopetalous, inferior, 
4-cleft corolla ; and the 4-valved, 4-celled capsule, with simple par- 
titions. 
Only one species known.

* From calluno, Gr. to cleanse, or adorn ; which is doubly suitable, whe- 
ther we lake it to express a cleansing property, brooms being made of this plant ; 
or whether we adopt the more common sense of the word, to ornament or adorn, 
which is very applicable to the flowers. Sir J. E. Smith. 
The Liiig f ('ultima vulgaris J is the badge of the Scottish Clan Macdonell.
