Root of branched fibres. Stem procumbent at the base, becoming 

 erect, square, simple, or branched below, roughish, with short recurved 

 hairs, especially above, leafy below and above, naked in the middle. 

 Leaves ovate, more or less heart-shaped at the base, unequally crenated, 

 rugose, downy, paler beneath and veiny, the lower ones usually with 

 long slender footstalks, the upper much shorter. Inflorescence axillary 

 whorls of numerous sessile flowers, crowded on the top of the stem. 

 Calyx tubular, ribbed and hairy, the teeth lanceolate awl-shaped, as 

 long as the tube, hairy, spreading when in seed, and the tube swollen 

 into a campanulate form. Corolla with a long slender tube, downy 

 outside, and with a hairy ring near the base within the throat, dilated, 

 the upper lip concave, obtuse, the lower one with the lateral lobes 

 furnished with two teeth each, the upper one awl-shaped, the middle 

 lobe cordate, marked with dark purple spots. Stamens covered by the 

 upper lip. Anthers two celled, hairy, scarlet. Seeds triangular, ob- 

 long, pale brown, often beautifully spotted with white. 



Habitat. — Borders of fields, gardens, and cultivated places ; common 

 everywhere. 



Annual ; flowering during the summer months. 



This very common Annual is variable in the shape of its leaves, and 

 their margin, which is sometimes entire, and at others unequally cut. 

 The flowers also vary in the greater or less intensity of their colour, 

 and are sometimes white. The odour of the whole plant is disagreeable. 



3. " L. interme' dium, Fries, (intermediate Dead-nettle). Leaves 

 orbicular, inciso-crenate, the floral ones sessile ; teeth of the calyx 

 subulate, longer than the tube ; tube of the corolla straight, with a 

 very indistinct hairy ring (none, Benth.) lateral lobe of the lower lip 

 with a short tooth."

Habitat. — Waste places about Edinburgh. — Mr. Tyache, Mr. W. 

 H. Campbell. Garden at Shrewsbury. — Mr. LeigJiton. 



Annual ; flowering from March to June. 



This plant has such slender claims to distinguish it as a species, that 

 we have thought it better to give Sir W. J. Hooker's own description ■ 

 but even he remarks " it is too nearly allied, I fear, to the following to 

 be deemed a good species." 



4. L. amplexVcaule, Linn. (Fig. 936.) Henbit Dead-nettle. Leaves 

 roundish, kidney-shaped, lobed and crenated, the upper ones sessile 

 embracing the stem, the lower petiolated; calyx with awl-shaped teeth ; 

 corolla tube straight, naked within, teeth of the lateral lobes of the 

 lower lip very small or wanting.
