Additional Floristic Results. 115 
yellow anthers (therefore not Robertianum) and almost odourless 
foliage. The specimen I examined has glabrous carpels, but I find 
in some others from Ballyvaghan a very few hairs are present. 
Jordan in constrasting Villarsianum with Robertianum does not 
mention the hairiness of the carpels, but he includes in his diagnosis 
“ glabris,” and his type specimen, which is young, at Kew, Mr. W. B. 
Turrill tells me has glabrous smooth carpels. But a point of interest 
arises. Is the hairy or glabrous character of the carpels adequate 
to separate the two groups? I have plants indistinguishable from 
Robertianum by other characters, and from inland situations, with 
glabrous carpels, whereas many plants passed as purpureum by 
British authors have more or less hairy carpels. It may be borne 
in mind that Syme (Eng. Bot. ii., 204) says the hairs are deciduous, 
and the hairiness varies greatly in quantity. However the 
monographer of the genus in the Pflanzenreich has quoted Rouy 
and Foucaud’s (Fl. Fr. iv. 95, 1897) arrangement, than which 
apparently he had nothing better to suggest. But it is quite evident 
that the last word has not been said upon the subject. Dr. 
Ostenfeld’s suggestion that at any rate his Clare specimens may 
represent a special variety is extremely probable, and closer 
attention being given to the group may show that Robertianum 
has a parallel series of variations to purpureum, and that in 
Britain we may possess several endemic forms. 
902. Potentilla procumbens Sibth. var. subsericea (Wolf in 
Mon. Potentil. 653, 1908, as forma), near Truro, I.P.E., 1911. I 
have also seen it near Penzance and from Dolgelly, Merioneth. 
927. Rosa sarmentacea Woods var. stenocarpa (Déség.), West- 
wood, York. I.P.E. 
942. Rosa omissa Déségl. var. submollis (Ley), Silverdale, 
Lancashire, I.P.E., 1911, teste Wolley Dod. 
1000b. Parnassia palustris L. (see p. 28). The dwarf plants 
with large flowers and fruits which we collected in the damp “slacks” 
of the Southport dunes, and which Dr. Graebner and myself thought 
formed a good variety, proved constant in the Berlin garden. Mean- 
while it has been described and named var. condensata by Travis and 
Wheldon (Journ. Bot. (1912), 254) who have had the plant under 
observation for some years. This year I have also seen it on low 
cliffs at White Park Bay, Antrim, and in Forfarshire on the Sands 
of Barry. 
1015. The new species of Sedum which Prof. Grazbner proposes 
to name after the writer has been already alluded to; it appears to 
replace S. acre in Britain so far as the native habitats are concerned. 
1077. Mesembryanthemum acinaciforme L. Under this name 
Prof. Graebner (p. 73) alludes to the Cornish plant. I am hoping 
to get Dr. Schönland’s opinion on it, as the plant was named 
aequilaterale by English botanists (see Flora of Cornwall), while 
I rather leant to its being M. edule. 
1260. Erigeron borealis (Vierh.)=E. alpinus auct. Brit. To this 
name Ostenfeld (p. 59) refers the British E. alpinus, differing as 
it does from the true plant by the obtuse basal leaves, the rather 
sparingly hairy base of the stem, and the strongly hairy, often purple 
phyllaries, characters which would have led me rather to call it var. 
borealis, than a distinct species.
