YORKSHIRE NATURALISTS’ UNION ON THE WOLDS. 305, 
another somewhat rare grass, confined mostly to calcareous districts, 
was seen. None but the generally-distributed Ferns were seen, such 
as Athyrium filix-femina Roth., Lastrea filix-mas Presl., and 
L. dilatata Presl.; the last-named being by far the most common fern 
met with in the de 
“CELLULAR CryptoGams.—The botanists who made this section 
of plants their main object of research, confined their exploration 
mostly to the trunks of the living trees growing up the sides of the 
dale. Earlier in spring or later in the autumn are more favourable 
seasons for the collection of this tribe of plants, not many being in 
active growth at this season. The following Mosses and Hepatics 
were collected :— 
Mosses. 
Isothecium myurum Poll. Neckera complanata L. 
Hypnum cupressiforme L. Orthotrichum affine Schrad. 
Hypnum resupinatum Wils. Orthotrichum lyellii H.& T. 
Plagiothecium denticulatum L. Ulota bruchii Hornsch 
Homalothecium sericeum L. Zygodon viridissimus Dicks. 
Leucodon sciuroides L 
All the above are of general distribution, and were gathered off the 
trees in the dale. TZhutdium recognitum Hedw. was growing on 
grassy banks by the sides of the calcareous roads. is moss has 
not hitherto been recorded for the East Riding, although it was 
gathered last year near Sledmere by Mr. G. Webster of York, and 
also previously i in the neighbourhood of Settrington by Mr. Slater. 
The plant is obtained in the calcareous tracts of the North Riding, 
in the Howardian tract, and in the neighbourhood of Hovingham, 
Hildenley, etc. It has, however, hitherto not been gathered in fruit. 
It is not recorded in Dr. Parsons’ list of East Riding Mosses. 
Lophocolea selina Schrad. Frullania dilatata L., in fruit. 
Metzgeria furc Radula complanata L., in fruit. 
All seen on the trees, and of general distribution. A small patch of 
the rare Ptilidium ciliare Nees var. pulchrum was gathered from 
a tree in the wood in York Dale. This is new to the East Riding, 
and is not in Dr. Spruce’s list. 
The Rev. E. Maule Cole, F.G.S., Teports for the Geological 
from Hull, etc., were met by Mr. Wilmot Cole, who con- 
ducted the party to a quarry east of the village, and on the northern 
slope of the slight eminence on which the village is built, chiefly for 
the purpose of showing the absence of flint in the beds of the Upper 
Chalk. Returning past the Vicarage, they were met by the conductor, 
the ae_Rev. E. Maule Cole, F.G.S., who guided them to a quarry on the
