parative absence of the Meadow Crane’s-bill. The distribution 
of these species in the Dale may be noted. Geranium 
sylvaticum, which blooms rather earlier, is the common one 
in the upper parts, and G. pratense in the lower. Incidentally. 
Wensleydale is rich in its number of British Geraniums, as of 
species of Speedwell, but G. sanguineum is not one of them. 
In order to complete the meeting, Ellerbeck was visited 
during the week following. A diligent search for the Alpine 
penny-cress ( Thlaspi occitanum ) did not reveal a single specimen, 
a somewhat remarkable experience, as Babington, in his flora, 
gives as the period for Thlaspi alpestre, June to August. 
Indeed this year there were blooms on March 7th, and similar 
dates have been established for the last seven or eight years. 
Scurvy grass likewise had mostly n n its course, as was the 
case with Primula farinosa, but the Thrift (Armeria 
maritima ) — in what might be described as a unique situation 
— and Arenaria verna were generally distributed and in fine 
condition. Though not conspicuous, Moonwort ( Botrychium 
Lunaria) and Selaginella Selaginoides were fairly common. 
Other species noted by members during week-end as having 
something of interest were : — 
Viola lutea var. amoena, Geranium lucidum, Potentilla 
verna, Myrrkis odorata, Peucedanum Ostruthium, Carum 
carvi, (at Marsett). Saxifraga tridactylites, Sax. hypnoides, 
Parnassia palustris (in bud). Galium Mollugo, G. erectum, 
Pinguicula vulgaris, Rumex domesticus, Orchis latifolia, 
Habenaria albida and Habenaria conopsea Benth = Gymnadenia 
conopsea Br. 
Mosses and Hepatics. — Mr. W. Ingham writes : — On 
Addlebrough a mass of the golden-yellow moss Hypnum 
chrysophyllum var. erectum Bagnall was found, also, in a hole, 
a very filiform form of Eurhynchium Swartzii was noted by 
Mr. Bellerby. 
By Semmerwater was abundance of Hypnum vernicosum, 
the typical plant, associated with the mosses Hypnum gigan - 
teum, Fontinalis antipyretica, Bryum bimum, and Mnium 
affine var. elatum. 
At Park Scarr were the mosses Swartzia montana, 
Trichostomum crispulum, typical, and Hypnum vernicosum 
with the hepatics Cephalozia bicuspidata, a very small form, 
and a large form of Lophozia ventricosa. 
At Mill Gill, in addition to common mosses, was the rare 
species Trichostomum crispulum var. elatum growing in crevices 
of rock close by the fall. 
In Whitfield Gill the dominant mosses were Brachythecium 
plumosum, Porotrichum alopecurum, Hypnum uncinatum and 
H. molluscum. 
On vertical cliffs on the left side facing the fall were many
