112 ANNALS OF SCOTTISH NATURAL HISTORY 



the point, as there is not even a record of the occurrence of 

 any species of this group, except Tate's erroneous one of H. 

 flocculosuin referred to below. 



The rocks and crags on the north shore of Roeness Voe 

 extend for a distance of some miles, and as the Hieracia 

 occur from near the sea-level to a height of 450 feet or a 

 little more, it is very probable that this rich locality will yet 

 afford additional species ; in the meantime the following are 

 the forms at present known to occur : — 



The abbreviations used are — 



U. = Unst. N. = Northmaven. 



Hieraciuin Schniidtii, Tausch. — N. North side of Roeness Voe, and 

 on the lower banks of the Orud Burn. The type appears to 

 be the less common form. 



Var. crinigerin/i, Fries. — N. In many places, north side of Roeness 

 Voe, Bjorgs of Skelberry, etc. 



Var. fealense^ Beeby, var. nov. — Leaves narrower, margins setose, 

 heads wath numerous glands. H. lasiophyllum, Tate ? — N. In 

 two places near the croft of Feal, Roeness Voe (Nos. 1045, 

 1 100). Mr. Linton writes: "Identical with the second example, 

 forma angnstifolia glandulosa^ in Lindeberg's No. 113. I have 

 not seen this before from Britain." 



The aggregate occurs in a number of localities from Clousta 

 northwards to the Kattaronis and Bjorgs of Skelberry. The 

 plants from the latter station (alt. 500 feet) w'ould probably con- 

 form to Mr. F. N. Williams' conception of the var. crinigeruvi ; 

 but I can scarcely think that the much more robust forms 

 growing among granite talus in the same locality, but 100-200 

 feet lower, are anything but the same. 



H. Oreades, Fries, var. siibglabratum^ F. J. Hanb. — Cliva Hill rocks, 

 north of Brae, Delting, sparingly (Nos. 1097, 1157). 



H. silvaticum^ Gouan, var. micracladiiwi^ Dahlst. (f.). — N. Among 

 crags, west of Feal, Roeness Voe, sparingly (No. 1094). 

 This is the plant formerly referred to H. duriceps^ F. J. Hanb., 

 from which Mr. Linton points out that it is at once distinguished 

 by the copious glandular hairs on the pericline. 



H. farre7ise^ F. J. Hanb. — N. Crags west of Feal, Roeness Voe, in 

 two places, alt. 400 and 450 feet (Nos. 1095, 1096). 



H. breve, Beeby, sp. nov. — Root-leaves broadly elliptic, with a short 

 broadly winged petiole ; teeth irregular, broadly triangular, 

 spreading, rather large. Stem -leaves similar, but narrower.
