Yorkshire Naturalists in the Ripon District.

At least two areas gave promise of good yield of species if it had not 
been so dry. It would be interesting if anyone living in the Ripon 
district could find all the molluscs reported in the Circular for 1905. 
Flowering Plants (J. M. Brown) : — While no strikingly new finds 
were made, the district proved of great interest to the botanists owing 
to the abundance of flowering plants, and to the wealth of blossoms 
which with the sunshine experienced, combined to give colour and 
brightness to the woods and lanes. The routes followed, keeping mainly 
to the valleys and by the waterside, resulted in moisture-loving plants 
being the most obtrusive. Particularly noticeable was the abundance 
of Epilobium angustifolium L. and E. hirsutum L. (Rose-bay and Hairy 
Willow-herbs), which gave the dominant colour effect to stream sides 
and clearings, of Mimulus luteus L. by the waterside, and on the shores 
of Eavstone Lake, the extensive areas occupied individually by Comarum 
palustre L. (Marsh Cinquefoil), Mentha verticillata Huds. (Mint), Iris 
Pseudacorus L. (Yellow Iris), and especially by the luxuriant growths 
of Scutellaria galericulata L. (Skull-cap). 
Of particular interest was the association of plants noted around 
the Lumly Moor Reservoir. Owing to the dry season the water level 
was low and a large area normally submerged had been left exposed. 
This strand was dominated in great part by Littorella uniflora Asch. 
(Shore-weed) plentifully in flower, but in places giving way to Peplis 
Portula L. (Water Purslane), also in flower, and to trailing growths of 
J uncus bulbosus L. Higher up the strand and in drier situations were 
limited patches of Gnaphalium uliginosum L. (Cudweed) and curiously 
stunted plants of Oenanthe aquatica Poir (Water Dropwort) probably 
representing material brought into the reservoir with the inflow. More 
landward still occurred Achillea ptarmica L. (Sneezewort) , Corydalis 
clavicularia DC. and (as pointed out by Mr. Winter) specimens of Plantago 
major var. intermedia (Gil.). At the upper inflow, a damp area showed 
a characteristic bog association dominated by Comarum palustre L., 
Menyanthes trifoliata L. (Bog-bean) and Mentha aquatica L. (Water 
Mint), but including abundance of Veronica scutellata L. (Marsh Speed- 
well), Hydrocotyle vulgaris L. (Marsh Pennywort), Lotus uliginosus 
Schk. (Marsh Bird’s Foot Trefoil) and Galium uliginosum L. (Bog 
Bed straw) . 
The most abundant aquatics appeared to be Potamogeton polygonifolius 
Pourr. and Myriophyllum verticillatum L. 
Epipactis latifolia Druce was seen plentifully in the Spa Gill Woods. 
Equisetum maximum Lam. was abundant, and Botrychium Lunaria Sw. 
was observed. 
Entomology (J. M. Brown) : — In spite of what appeared to be 
particularly favourable conditions both as regards weather and locality, 
insects of most orders seemed distinctly scarce. Considering that the 
expeditions were mainly in the immediate neighbourhood of water, 
either as streams or ponds, the paucity of Stone-flies, Caddis-flies, 
Dragon-flies, and May-flies, whose larvae live in such places, was 
particularly noticed. Under such circumstances few rarities were 
taken. Hemiptera and Psocoptera seemed more numerous, and there- 
fore most attention was given to these groups. 
Beetles, butterflies, bees and wasps, and saw-flies were not much 
in evidence, but the Wood Ant ( Formica rufa L.) was quite plentiful 
in Piclcingill, where a large number of nests, composed as usual of pine 
needles, were noticed. 
Plecoptera. — Very few Stone-flies were seen. Those taken were : — 
Isoptera tripunctata Scop. Leuctra geniculata Steph. 
Leuctra klapaleki Kmpy. Amphinemura cinerea Oliv.
