230 ANNALS OF SCOTTISH NATURAL HISTORY 



Artemisia vulgaris, Cichorium Intybns, SoncJins oleraccus, 

 Scutellaria galericulata, Bromus sterilis. Almost all of 

 these were present in 1898 in only small numbers, except 

 where they grew in clumps that were destroyed by the 

 extension of the area covered with cinders. 



The following species observed in former years, but not 

 in 1898, recurred in 1899, chiefly on rubbish - heaps : 

 Saponaria Vaccaria, Malva parviflora, Geranium molle, 

 Scandix Pecten- Veneris, Caucalis latifolia, Centanrea Cyanns, 

 SoncJins asper, PJialaris arnndinacea, Festnca rnbra. 



The following, also chiefly on rubbish -heaps, had not 

 been previously observed on this ground : Barbarea vulgaris, 

 Sambucus nigra, Galinm tricorne, Anthemis Cotula, EcJiino- 

 spermum Lappnla. 



ON HIEROCHLOA BOREALIS, R. & S., 1 AS A 

 SCOTTISH SPECIES. 



By ARTHUR BENNETT, F.L.S. 



THE discovery of this species by Miss Mittelbach on the 

 shore of Kirkcudbrightshire makes it perhaps possible that 

 it may be found in other localities ; but it must be searched 

 for early, since from the first week in May to the first week 

 in June seems the time in Scotland when this grass is in its 

 best condition. In cultivation of the plant, however, from 

 the Thurso station, I found it begins to flower as early as 

 i 3th April, but is at its maximum about the middle of May. 

 It flowers profusely when grown in a pot, but very sparsely 

 in the ground, among Carex tomentosa, SisyrincJiinm, etc. 



In this note I propose to give an outline of its history as 

 a Scottish species (with extracts from various sources, letters, 

 etc.), its distribution in Europe, etc. 



The first notice of it as a British plant seems to be in 

 Hooker's "Flora Scotica," p. 28, 1821, where it is recorded 

 as " in a narrow mountain valley called Kella, Angus. G. 

 Don. A valuable discovery of the late acute Mr. G. Don ; 

 called Hierochloe by Gmelin, because in some parts of the 



1 Gmelin, " Fl. Sib.," i. p. 101 (1747), wrote "Hierochloe."
