30 The Scottish Naturalist. 



J. lamprocarpus Ehrh. Here and there, but not so com- 

 mon as J. supinus. 



J. Gerardi Lois. N. Marshes near the sea at Queyfirth ; on 

 the shore near OUaberry. I was unable to detect J. compressus. 



Schcenus nigricans L., var. nana Lange (in litt.). U. 



Abundant on the hills north of Baltasound, the locality mentioned 

 by Edmonston, and uniformly, whether in wet or dry, low or high 

 places, of a very small size 5-8 inches high. Whether it differs 

 from the type in any more important characters I cannot say, as- 

 it was only in early flower. 



% Scirpus acicularis L. U. Queyhouse Loch, a branch of 

 the Loch of Cliff. 



* S. uniglumis Link. U. about the Loch of Cliff, abundant 

 at the south end. N. Salt marsh near Queyfirth. 



X S. pauciflorus Lightf. Rather common. U. Common in. 

 north Unst. N. Bogs near Hillswick ; bogs and roadside ditches 

 about OUaberry. 



Gar ex. All the species accepted for Shetland in Top. Bot, Ed. 

 II., were noted, and most of them collected, with the exception of 

 C. incurva and G. capillaris, the localities for which were not 

 visited ; and G. prcecox, which must, I think, be excluded on 

 present knowledge. It is recorded by no one except Edmonston, 

 who speaks of it simply as " common,"' but I failed to find it. On 

 the other hand, Edmondston does not mention G. pilulifera at 

 all. This is recorded by Tate from Scarpoe, Unst, and is in 

 reality general and rather common. I think, therefore, that the 

 latter plant probably represents Edmondston's G. prcecox. 



C. pilulifera L. f. reptans Lge. U. Grass slopes above 

 Burrafirth cliffs ; a form with slightly creeping and rooting stems, 

 not at all crespitose. 



C. binervis Smith. Rather frequent ; a small form from (U.) 

 Saxa Vord Hill ; and (N.) wet rocks by Ronas Voe, is thus- 

 characterised by Dr. Lange : " f. gracilior ! vix ultra J ' longa, 

 culmus gracilis, subflexuosus, spicse feminese breviores quam in 

 forma typica." The Ronas Voe plant is a remarkably dwarf one, 

 not unlike G. prcecox in look ; but as examples from the various 

 districts show a gradual transition to fairly typical plants 18 inches 

 high, I hesitate to give it a varietal name.
