n 4 ANNALS OF SCOTTISH NATURAL HISTORY 



H. dovrense, Fr. 



Sub-sp. humidorum, Almq., var. Hethlandiae (F. J. Hanb.). 

 Cliva Hill Rocks, Delting, in some plenty (Nos. 1107, 1151). 



Sub-sp. demissutn, Stromf., var. australius, Beeby, var. nov. 

 Considered by Dr. Almquist to be closely allied to the Icelandic 

 If. demissum, from which it differs in the more numerous stem- 

 leaves, the upper ones more amplexicaul, and the lower ones 

 less attenuated towards their base. Pericline short, broad, 

 truncate -based, blackish, sub-glabrous, with a few glandular 

 hairs. Ligules glabrous, styles livid. H. crocatum, Tate ? 



U. In some plenty about the north-east corner of the Loch 

 of Cliff; Burrafirth Cliffs (Nos. 609, 859, 860). 



Sub-sp. demissum, Stromf., var. pulchelliforme, W. R. Linton, 

 = H. pulchellum, auct. brit. 



Dahlstedt places this near H. demissum, while Almquist 

 regarded it as very closely allied to, but distinct from, the 

 last, thus assigning it a similar position. 



U. Burrafirth ! W. R. Linton. North-east banks of Loch of 

 Cliff; by Queyhouse Loch (No. 608). 



H. protractum, Lindeb. = H. vulgatum, Tate. In many places from 

 Unst and Yell southwards to Sandsting and Aithsting. The 

 form with marbled leaves is the more common (Nos. 610, 611, 

 1093, etc.). 



H. subtruncatum, Beeby, sp. nov. Pseudophyllopodous ? Root- 

 leaves ? Stem -leaves numerous, about 10-13, lanceolate or 

 ovate-lanceolate, all sessile, upper clasping with a broad base, 

 lower less so, with a few medium-sized more or less spreading 

 teeth, a few long hairs on both sides, and rather many stalked 

 stellate hairs beneath. Stem purplish red, hairy, especially 

 below, branching dichotomously, branches sub-erect, 12-25 

 inches high according to situation. Peduncles sparingly 

 floccose, with a few simple and glandular hairs. Pericline 

 somewhat rounded below, outer phyllaries short ovate, inner 

 lanceolate, all more or less blunt ; the recurved tips violet- 

 coloured in the living plant, very faintly floccose, otherwise 

 glabrous. Flowers rather pale, ligules glabrous, styles yellow. 



This plant has been referred to H. truncatum, Lindeb., by 

 Dr. Elfstrand and the Rev. E. F. Linton, but that species 

 differs conspicuously in its glabrous leaves, and in the long, 

 winged petioles to the lower stem-leaves. It differs also from 

 the Shetland plant in the following points among others 

 stem-leaves fewer, 5-7, broader in the middle, stem glabrous, 

 phyllaries slightly floccose and senescent, panicle with branches 

 "arcuato-patentibus," etc. Mr. Linton writes: "In all the 

 above points Lindeberg's H. truncatum contrasts markedly
