Gen. Char. Calyx (fig. 1.) inferior, 4-parted, with a naked 
base. Corolla (see fig. 2.) of 1 petal, globose, or bell-shaped, often 
ventricose, with a 4-cleft limb. Pilaments (see fig. 3.) 8, hair-like, 
arising from the receptacle. Anthers (see fig. 4.) terminal, up- 
right, cloven, opening by lateral orifices, which adhere to those of 
the next anther till the pollen is discharged. Germen (see fig. 5.) 
superior, roundish. Style (see fig. 5.) thread-shaped, upright. 
Stigma blunt. Capsule (see figs. 5, 6, & 7.) roundish, with 4 fur- 
rows, 4 cells, and 4 valves, each bearing a dissepiment (partition) 
from the centre (see fig. 7). Seeds (figs. 8 & 9.) numerous, minute. 
The 4-parted calyx , naked at the base ; the monopetalous, glo- 
bose or bell-shaped, often ventricose corolla; and the 4-celled, 
4-valved capsule, with the dissepiments from the middle of the 
valves ; will distinguish this from other genera in the same class 
and order. 
Seven species British, 
ERI'CA TE'TRALIZ. Four-leaved Heath. Cress-leaved Heath. 
Besom Heath. 
Spec. Char. Leaves 4 in a whorl, ciliated. Flowers capitate, 
terminal. Corolla egg-shaped, as long as the style. Anthers with 
two spear-shaped spurs at the base, included.

* From erico, Gr. or ereico, Gr. to break ; from the supposed quality of some 
species in destroying calculi in the bladder. 
Within the last twelve years four species of this beautiful genus have been added 
to the British Flora; namely, E. Mackuii, E. Mediterrdnea, E. cornea, and 
E. cilia r is. f See folio 42, note t.
