FUBT9EB NOTES ON HLERACIA. 207 



drying, and I have bad it in constant cultivation since. During the 

 same month Dr. White found it at Loch Voil, whilst Mr. Marshall 

 collected it a few days earlier on the Glen Etive side of Clach 

 Leathad, Argyle, writing on the label of the specimen he sent me, 

 " This I consider an extremely well-niarked plant*" In 1886 

 I gathered fine specimens by the Dee, near Braemar, but at that 

 time they were simply put aside, as Mr. Backhouse returned them 

 to me without any attempt at naming them ; whilst in 1887 the 

 crags in Glen Callater yielded a further locality ; and in 1890 the 

 Rev. E. P. Linton sent me the same plant from Glen Dole, Forfar. 

 Last year Mr. Marshall collected it on Ben Chaistel, near Tyndrum, 

 and, what are probably weak specimens of the same thing, from 

 Glen Lochay ; whilst the Rev. Augustin Ley and I found it in 

 splendid condition on Craig Dulyn, Carnarvon, near Babing ton's 

 original station, from which locality a full description and excellent 

 drawing were secured. 



Allied to H. ccesmm in some respects, notably in general appear- 

 ance, arrangement of leaves, size, &c, it differs from all forms of 

 that species in important particulars, the long, narrow, cylindrical 

 buds, short divaricate peduncles, and frequently adnate heads 

 affording a facies by which it may be easily recognised. The plant 

 ranges in height from 10 to 18 in. Radical leaves ovate-lanceolate, 

 acute, almost entire (in Wales), or somewhat coarsely toothed (in 

 Scotland), gradually tapering into (usually) rather long petioles; 

 bright grass-green, softly hairy on both surfaces, clouded with 

 purple beneath. Stem reddish below, with few long hairs, but 

 rough with short downward-pointing bristles, usually bearing one 

 large shortly-stalked leaf, and often a much smaller one at the 

 point of branching. Heads often crowded, two or three being borne 

 on very short straight peduncles at the end of remarkably straight 

 and divaricate branches, or singly on long straight peduncles. 

 Peduncles very floccose, sparingly hairy and setose. The mature 

 involucre very truncate and conical, dark green to purplish. Phyl- 

 laries appressed, rather blunt, margins paler, floccose-tipped when 

 young, as in H. senescens, clothed with numerous white black-based 

 hairs, and very sparingly floccose and setose. Ligule glabrous at 

 the tips when expanded, scarcely ciliate when young. Styles faint 



olive-green beneath. 



H. lasiophyllum Koch, var. planifolium, n. var. — A peculiar 

 form that as yet I have only seen from the Great Doward Hill, 

 Hereford, growing quite near the locality for the type, from which 

 it differs in the remarkably broad, flat, ovate and very truncate- 

 based radical leaves, which are softly hairy, and borne on long 

 shaggy petioles. The stem is ordinarily simple, dividing at the top 

 into° from two to four rather short, erect peduncles, giving the 

 panicle a crowded and very narrow appearance. The heads are 

 small, but in other respects resemble the type. When I gathered it 

 with Mr. Ley in 1889, I referred it to a form of R. pallidum Biv., 

 but on a sheet sent with other things to Dr. Lindeberg he erased 

 this name, adding, " Non H. pallidum, cujus folise sunt rigide 

 pilosa, nee, ut in hac forma, molliter ! Folia Hieracii pallidi sunt
