JUNE. 185 
Horehound. The English name is derived from the plant 
yielding a black dye, which is used by gypsies to stain their 
faces. There is only one species, which grows in ditches 
and on river-banks. The leaves are opposite, with short 
stalks, wrinkled and very deeply cut at the edges. Flowers 
small, whitish with purple dots, and in thick whorls at the 
base of the leaves. Stem about two feet high, erect, and 
four-sided.

cup-shaped disk. Corolla of two petals. Seed-vessel of two cells,

Circma LureTtana. (Plate XII. Fig. 45.) Common En- 
chanter’s Nightshade. This is one of the most elegant wild 
flowers we have. It is common in shady woods and coppices, 
rocky banks, &c. Its small white or rose-coloured flowers 
are well worthy of examination; they grow in a long spike, 
rather distant from each other, and leave a hairy seed-vessel.
