axillar rosettes; 4) a large central rosette at the base, 
even in the biggest specimens, like that of S. saginoides ; 
5) peduncles longer and thinner; 6) the majority of the 
flowers abortive and a great many of them fading at 
an early state, in spite of the considerable length of 
the peduncle. 
I suppose that these specimens were considered by 
Brügger as either doubtful or hybrid, for he has left 
them wflthout names. They are collected in Graubün- 
den, at Cresta, river Avers (teste Thellung et Seiler in 
schedula!), and not far thus from the Bernina Alps. 
Another quite similar specimen also exists in the same 
Herbarium, labelled only »Via mala, Thusis». 
Although this aberrant Sagina in Brügger’s Herba- 
rium (there are a dozen large tufts of it) has merely 
tetramerous flowers, there can be no doubt as to its 
hybrid nature, and the characteristics seem only to point 
out a combination of procumbens and saginoides. The 
specimens are also very much the same in size and 
growth as the hybrid specimens of other collections. 
If the tetramerous flowers indicate a form nearer to S. 
procumbens , such a form in a hybrid series cannot be 
unexpected. I therefore think there is in Brügger’s 
Herbarium quite sufficient material of a » Sagina media». 
There are thus two older specific names, media 
(1880) and Normaniana (1898j, which could be substi- 
tuted for scotica , and provided they all refer to the 
same plant, the latter should be called Sagina media 
Brügger, the name possibly to be taken in a broader 
sense than originally. 
Should this widely distributed plant in its whole 
extent also be considered as a mere hybrid? There 
may, theoretically, exist grounds for that view, but there 
is no complete evidence, and practically it is very tempt- 
ing to treat this plant as a species on account of its 
wide and fairly continuous distribution, well-marked dif-
