THE SEGREGATES OF SPERGULA ARVENSIS L, 175 
any seeds of S. vulgaris without, nor any plants with intermediate 
characters. I have seen plants which were labelled «3. sativa 
with seeds having a few papille,” but the sheet so labelled 
in the Boswell Herbarium will be seen on examination to consist 
of two plants fastened down together, one S. sativa, the other 
S. vulgaris. 
As to the distribution of the two plants, my observation 
bears out Mr. Nicholson’s statement that S. sativa is the Scotch 
plant. Up to now I have not seen any Scotch specimens of S. 
Oo 
Westerness, Easterness, Nairn, Banff, Aberdeen N. and §., Forfar, 
Perth E., M. and W., Stirling, Edinburgh, Peebles, Wigton, and 
Kirkeudbright. 
England and Wales I have seen it in Cumberland, West- 
moreland, Durham, York N.W., Oxon (very rare), Berks (rare), 
Anglesea, and Carnarvon ; and in Ireland in Co. Dublin. 
the Boswell Herbarium 8. sativa is represented by specimens 
from Lancashire, Cheshire, Salop, Orkney, Lanark, Cardigan, 
Surrey, Essex, Middlesex, and Antrim 
- vulgaris is the common plant of Central England. I have 
collected it in Lincoln §., Warwick, Gloster E., Northants, Beds, 
Bucks, Oxon, Berks, Sussex E., Hants N. and §., Wilts N., Dorset, 
rk, , and Dublin. 
The Boswell Herbarium contains specimens from Cheshire, 
Lincoln, Surrey, Middlesex, Somerset, and Jersey. 
e O: Herbarium we have S. sativa from Khasia 
(Hook. f. et T. sub nom. S. pentandra) ; St. Petersburg (Fl. Ingric. 
122); Portugal (Welwitsch 812); Sweden (Rel. Maill. 929). I have 
seen it in ce, Spain, and Germ 
S. vulgaris is represented b imens from Marocco; Russia ; 
near Paris (Rel. Maill. 198); Sicily (Todaro 985); Greece (Melos). 
I have seen it in Belgium, Holland, France, Austria, Switzerland, 
S. sativa for fodder purposes. §. maxima has papillate seeds, hence 
it comes under S. vulgaris 
To sum up—I would 
rv 
claim specific rank for these two segregates 
of the Linnean S. a J i 
ensis, basing my conclusion on the constant 
in mind. If they be given specific rank, we shall have to call the 
plant with papille S. arvensis L. Sp. Pl. ed. 1,440, et Herb.! The 
plant without papille on the seed will be S. sativa Boenn., thus 
reversing Reichenbach’s determination.
