WILD FLOWERS OF THE BRITISH ISLES 
Lower corolla-lip with a large central lobe and 2 small side lobes which are more like 
teeth ; anthers hairy. 
(1) Henbit Dead-Nettle. (Lamium amplexicaule.) — Calyx densely hairy, teeth closing 
in fruit ; corolla-tube straight, without an internal ring of hairs ; upper leaves 
stalkless. 
(2) Intermediate Dead-Nettle. (Lamium molucellifolium.) — Calyx-teeth slightly hairy, 
spreading in fruit ; corolla-tube straight, short, with an indistinct ring of hairs inside ; 
upper leaves stalkless. 
(3) Cut-leaved Dead-Nettle. (Lamium hybridum.) — Calyx-teeth spreading in fruit ; corolla 
tube straight, without a ring of hairs inside ; leaves all stalked. 
(4) Red Dead-Nettle. (Ldmium purpureum.) — Corolla-tube curved, with a marked ring 
of hairs inside ; leaves all stalked. 
(5) ^Spotted Dead-Nettle. (Lamium maculatum.) — Corolla-tube curved, with a marked 
transverse ring of hairs inside ; leaves all stalked. 
(6) White Dead-Nettle. (Ldmium al'bum.) — Flowers white; corolla-tube curved, with 
a marked oblique ring of hairs inside ; leaves all stalked. 
Lower corolla-lip with 3 entire nearly equal pointed lobes ; anthers not hairy. 
(7) Yellow Dead-Nettle. (Ldmium Galeob'dolon.) — Flowers yellow; corolla-tube curved, 
with a marked oblique ring of hairs inside ; leaves all stalked. 
1. Henbit Dead-Nettle. (Ldmium amplexicaule. Linn.) — As just described. The 
flowers are about § inch long, of a purplish-rose, in distant clusters in the axils of the opposite 
leaves (false whorls) ; the calyx is small and densely hairy, the teeth longer than the tube and 
converging in fruit ; the tube of the corolla is long, straight and slender, without an internal ring 
of hairs, the upper lip is entire and the lower lip has a large central lobe and 2 teeth-like side ones ; 
and the anthers are hairy. The stem is 4-12 inches high and is branched from the base; the 
leaves are roundish, partly heart-shaped (subcordate) at the base and bluntly scalloped (crenate), 
the lower ones on long stalks and the upper ones stalkless (sessile). 
Common. In cultivated ground and waste places, on sandy and chalky ground ; generally 
distributed throughout England, Scotland, and Ireland. May — August. Annual. 
2. Intermediate Dead-Nettle. (L&mium molucellifolium. Linn.) — A species inter- 
mediate between the Henbit Dead-Nettle (Lamium amplexicaule) and the Red Dead-Nettle 
(Lamium purpureum), though with more of the characteristics of the former, from which it differs 
in the calyx being less hairy, the teeth spreading in fruit, and in the corolla having a shorter 
tube and an indistinct ring of hairs inside. {Lamium intermedium. Fries.) 
Local. In cultivated ground on sandy soil ; common in Scotland, rare in England and Ireland. 
June — September. Annual. 
3. Cut-leaved Dead-Nettle. (L&mium hybridum. Villars.) — Another intermediate 
species, but more closely resembling the Red Dead-Nettle (Lamium purpureum). The flower- 
clusters are more crowded together at the top of the stem, as in that species, the flowers are 
red and about \ inch long, the calyx-teeth are spreading, the corolla-tube is straight and without 
any internal ring of hairs, and the leaves are all stalked and deeply scalloped (crenate), the 
upper ones wedge-shaped at the base, only the lower ones being heart-shaped (cordate). {Lamium 
incisum. Willd.) 
Rather common. In cultivated ground and waste places ; generally distributed throughout 
England, Scotland, and Ireland. April — October. Annual.
