whole of its large area, it is very tempting indeed, not- 
withstanding its predominating sterility. 
As to the Sagina Normaniana from Tromsö, Pro- 
fessor Lagerheim has laid stress on the hybrid nature 
of the specimens found there, and in his paper quoted 
above he says: »eine Sagina-Form, welche die Charac- 
tere der Combination S. Linnæi X procumbens unzwei- 
felhaft und deutlich aufweist». He points out that the 
greater part of the capsules are »verkümmert und leer», 
and the pollen »sehr schlecht; nur wenige Procent Pol- 
lenkörner sind gut entwickelt» etc. Moreover, Prof. 
Lagerheim lias informed me that his discovery was not 
a mere chance, as he went out with the express inten-

had to examine a great number of the latter, before he 
came across it late in the summer of 1894. 
Some other facts which seem to indicate the hybrid 
nature of this Sagina, as regards the Scotch specimens, 
have been pointed out by Dr. Ostenfeld in the New 
Phytologist 1912, p. 117. 
I admit that much of its structure and behaviour 
seems to indicate the hybrid character and intermediate 
position of this Sagina, but several features might be 
said to point to a distinct species of a quite peculiar
