118 HTERACIUM. 



twisted towards the points, which are revolute in the buds. The 

 ligules of the flowers are smooth and quinquefid, and the revolute 

 styles dark brown. The fruit varies in colour from yellowish to dark 

 chestnut-brown, according to its stage of maturity, is smooth, deeply 

 grooved longitudinally, entire at the apex, and crowned with a copious 

 rough pale yellowish papj)us. 



We have three varieties of H. murorum. Var. a. Plate II. fig. 1. 

 = Pulmonaria gallica, sive aurea latifolia — Ger. Em. 304, — a cha- 

 racteristic figure. The leaves somewhat resemble the small leaves 

 of the Coltsfoot, and are deeply empurpled on the \inder surface, 

 while the upper surface is " of an elegant opake, rather glaucous 

 green." They are ovate-acute or ovate-lanceolate, cordate at the 

 base, and cut into small segments there which look backwards, the 

 margin otherwise being obsoletely sinuated, having the slight pro- 

 jections tipt with a blunt gangrened mucro. It is a graceful plant, 

 often met with on the steep scaurs of the Tweed and Whiteadder, 

 especially where shaded from the sun. I have seen it plentiful on the 

 banks below Norham Castle; on the south bank of the Whiteadder 

 in Tibby Fowler's glen ; and on tl^e sea banks at Burnmouth, &c. 

 — Our var. /3. Plate II. fig. 2. ( = Broad dented Hawklung, Petiv. 

 Eng. PI. tab. xiii. fig. 3) grows in abundance in Dunsdale on Cheviot, 

 and it may be the II. plumbeum described by Mr. Baker in the 

 Phytologist for 1852, p. 453. In this variety, Avhich is a larger plant 

 than var. a, the leaves are more elongated and more numerous, ovate- 

 lanceolate, incised at the base, and narrowed there, so as to run in- 

 sensibly into the stalk, and the mucronated angles are either patent 

 or pointed forwards. The plant has much of the succulent character 

 of the Crepis paludosa. — Our third A^ariety y. (Plate II. fig. 3.) is a 

 smaller and less attractive plant than either of the preceding, and is 

 at once distinguished by having its leaves marked with irregular black 

 blotches, as those of H. maculatum are described to be. I have seen 

 it only on the rocky face of the hill above Yetholm manse, where it 

 grows in considerable quantity. The root is woody and scaled with 

 the remains of old leaves. The leaves, often numerous, are ovate or 

 elliptical, so obsoletely waved on the margin as to be properly 

 described as almost entire; but there are distant mucro-like den- 

 ticles above, and at the base one or two small teeth with a backward 

 direction. The stem is leafless, often oblique, and with from two to 

 five flowers. 



351. H. SYLVATicuM. Plate II. fig. 4. "Leaves ovate-lanceo- 

 late, toothed chiefly about the base ; teeth pointing forward." — 

 Leaves few, elliptic-lanceolate, narrowed below, and running insensibly 

 into the stalk, which is about half the length of the leaf; the margin 

 cut or toothed at the base, the segments pointing forward, tipt with 

 a blunt mucro ; and this mucro alone remains towards the apex : 

 upper surface sparingly hispid, more or less blistered, and the inferior 

 is frequently empurpled. Stem firm, erect, with usually two small 

 sessile leaves, divided above in a forked manner, and having from five 

 to twelve flowers. There is a small bract at the base of every flower- 

 stalk, which is clothed with down and spreading black hairs. Scales
