403 (2). Sagina scotica Druce in Rep. of Bot. Exch. Club 
(1911) 14 April, 1912. This is the Ben Lawers plant which in my 
paper (p. 26) | named S. glabra Penzl. var. scotica; but even before 
the paper was printed I had seen that it could not be put under that 
species, since the Tirolean specimens with which I had compared it 
were, | found, not authentic. The petals of S. glabra are much 
longer than ours, besides other marks of distinction. This was 
borne out by specimens of true glabra kindly sent me by Prof. 
Schroeter. Dr. Ostenfeld identifies it as Sagina procumbens x 
saginoides—S. media Brigg (but with a wrong synonym-—it should 
read S. glabra var. scotica Druce, not S. glabra Druce). This was 
his view at the time, and although strongly controverted by one or 
two of our confreres has some probabilities in its favour, though I 
think he places too much stress on the supposed barren condition 
offthe plants. But its great abundance over considerable areas, its 
different flowering time, and to me the absence of evidence of the 
presence of saginoides in it led me to adopt Prof. Graebner’s view 
that it was a distinct plant, which I have named scotica in the work 
cited above. Since doing so Prof. Graebner writes (July 8th, 1912) 
“the Sagina from Ben Lawers grows very well, it has flowers and 
well developed ripe fruit. It is right to take it as a species; it is 
very characteristic and cannot be a hybrid,” and on August 21st 
“it is impossible that S. scotica is a hybrid! we cultivate it with 
saxatilis (saginoides), but 1 cannot find anything of this plant in S. 
scotica. It is without doubt near procumbens, but a quite different 
plant. It has had good fruits.” In culture I find that it produces 
good seed, and although reverting in appearance towards pro- 
cumbens, still I think keeps distinct. In my paper I suggested that 
it would prove to be often named saginoides (or by one of its 
synonyms) in herbaria, and I find quite a considerable portion of 
Scottish saginoides to be really scotica, It exists under that name 
in Babington’s Herbarium. The acute botanist, Mr. Webb, had 
also in Herb. Edin. first labelled specimens of it S. saxatilis and 
subsequently thought it to be S. procumbens, while there are other 
specimens under saginoides on various sheets. S. scotica is not 
confined to Ben Lawers, for I have seen it from Craig Chailleach 
in Mid Perth; from Glen Callater, S. Aberdeen, and from Clova, 
Forfar; a distribution itself somewhat antagonistic to its being of 
hybrid origin. 
488. Geranium Robertianum L. var. Villarsianum (Jord). Dr. 
Ostenfeld (pp. 57-58) believes the forms he collected in the west 
of Ireland cannot belong tothis name. But while it is quite possible 
that he is correct, it is by no means certain whether we are speaking 
of the same gathering, since I had three distinct sets, two of which 
must be put under Robertianum (see p. 41) and another (Ref. No. 
4581) from the rocks west of Ballyvaghan, which is apparently a 
local form, since plants from the vicinity sent me this year by Mr. 
P. O’Kelly are not. identical. Mine were small prostrate plants 
agreeing very closely in facies with Jordan's type Villarsianum, had
