the fields adjoining Riccia glauca. Linn. Campanula, glomerata is plentiful along 
the bank, as also is C. latifolia. Respecting the latter plant, Thomas Johnson, 
who in 1633 wrote an edition of " Gerard's Herbal," says : — "I have found this 
plant growing on the banks of the River Ouse, between York and Selby, the 
place where I was born." 
Near Barlby may be seen Colchicum autumnale, now in fruit, and occasional 
spikes of Botrychium lunaria. 
Leaving the river bank at Turnhead Farm and crossing the railway bridge 
Rhinanthus major, Ehrh. is seen along the road side, and in the first wood on the 
right Pyrola minor. Now the Common is reached may be found Corydalis 
claviculata, Stellaria glauca, Hypericum elodes, Sium latijolium, Arctium majus, 
Pimpinella magna, Droscva rotundifolia and intermedia, Polygala vulgaris, Gentiana 
Pneumonanthe , Menyanthes trifoliata, Ptnguiciila vulgaris, Utricularia vulgaris, Hottonia 
palustris, Nasturtium amphibium, Vaccinium Myrtillus, in Cliff Common Wood and 
on the Common near Skipwith. Epipactis latifolia, Hahcnaria bi folia, Mentha 
Pulegium in ponds near Skipwith Church, and on the Churchyard wa.\ls A spleniutn 
ruta-muraria. Isoetes lacustris, and Pilularia globulifera should be looked for in the 
shallow ponds. They were formerly abundant. The latter still grows in two or 
three places, but Isoetes has not been seen for some years. 
Some six or eight species of the Order Ciiaraceoe await definite determination. 
Mr. Wm. Ingham, B.A., adds: — Riccall Common has been well worked for 
these plants. Early in May the following may be found in flower: — Ranunculus 
sardous, Corydalis claviculata, Scleranthus annuus, Ornithopus perpusillus Alchemilla 
arvensis, Apium inundatum, Samolus Valerandi, Littorella uniflora, Alisma ranuncui aides, 
Scirpus fluitans, Carex pulicaris, C. ovalis, C.panicea, C. dioica, Apera spica-venti, 
Equisetum palustre and E. limosum. 
Mosses and Hepatics. — The Yorkshire Bryological Committee will 
be officially represented by the Chairman, Mr. Wm. Ingham, B.A.. 
Mr. Wm. Ingham, B.A., writes: — Riccall Common is rich ground in all the 
departments of Bryology. Selecting from a long list the chief are the following — 
I. — SPHAGNA. 5 laricinum, S. cuspidatum var. falcatum, S. fimbriatnm var. 
vohustum, S. crassicladum, S. rufescens, S. subnitens, with several of its varieties, 
S. inundatum, S cymbifoliuift of several varieties, and a beautiful Sphagnum 
S. papillosum var. sub-lave, forma glaucescens. 
II. — HEPATICS. Fossombronia Dumortievi, Lothozia gracilis, Cephaloziella 
bifida, Calypogeia fissa, Scapania irrigua and Blepharozia ciliaris. 
III. — TRUE MOSSES Polytrichum gracile, P. commune var. fastigiatum, 
Campylopus atvovirens var. gracilis, C. fragilis, C. brevipilus, Dicranella cerviculata, 
Dicranum spurium of fine growth, Hypnum elodes, H.polyganum var. stagnatum, 
H. stellatum, H. Wilsoni and its var. hamatum, H lycopodioides, a rare moss in 
extensive sheets, H. fluitans and its vars., J eanbernati, gracile, falcatum, and Arnellii, 
the last very rare variety in extensive sheets, H. exannulatum and its vars., 
brachydictyon and falcifolium, H. revolvens. H. intermedium fruiting, H. falcatum, 
H. imponens, H. molluscum, a marsh form, H. scorpioides, H. stramineum, H. 
cordi folium fruiting, and H. giganteum. 
Fungi. — The Yorkshire Mycological Committee will be represented. 
Mr. W. N. Cheesman, J. P., F.L.S., writes: — The woods surrounding the 
Common have been well worked at several forays for autumnal species, and 
many rare and interesting records have been made, viz. : — Lepiota metulcespora, 
L. delicata, Tricholoma onychinum, T. lascivum, Clitocybe ericetorum, Mycena 
hamatopoda, Volvaria speciosa, Eccilia atropunctata, Pholiata aurea, Flammula 
gummosa, Cortinarius tabularis, C. hemitrichus , Gomphidius roseus, Paxillus arcelloides, 
Lactarins circellatus, Russula xerampelina, Boletus spadiceus, Polystictus radiatus- 
Craterellus sinuosus, Hymenochate fuliginosa, Peniophora rosea, Cordyceps ophioglossoides, 
parasitic on Elaphomyces granulatus, Rhizina inflata, Peziza mellea. It is very desir- 
able that vernal species should be now recorded, few Agarics will be seen, but a 
look out might be made for Morels and allied genera, as several are known to occur 
but have not been officially recorded. The Mycological Committee will be 
pleased to receive any specimens of the groups Ascomycetes, Hyphomycetes and 
Mycetozoa, as the records for these are at present very incomplete for the 
Common. 
MICRO-ZOOLOGY and BOTANY.— This Section will be officially 
represented by its Secretary, Mr. J. W. H. Johnson, B.Sc, F.L.S. 
VERTEBRATE ZOOLOGY.— The Vertebrate Section will probably 
be officially represented.
