Botany. — Mr. J. F. Robinson writes: — The botanical 
contingents did excellent observational work on both Saturday 
and Monday along the coast southward of Filey. ‘ Primrose 
Valley,’ a quite considerable ravine which bifurcates inland 
at a few hundred yards’ distance from the sea-shore, is cut into 
the Boulder Clay, the steeply sloping sides being well covered 
with a very varied vegetation. Here the botanists lingered 
long and had a good time before moving half-a-mile further 
on to the ‘ Flat Cliff ’ a form of undercliff caused by the slip- 
ping of the Boulder Clay. The grassy undulations of the 
‘ Flat Cliff ’ and the numerous ponds in the hollows thereof 
proved particularly interesting. In both places the assemb- 
lage of plant forms was of a very mixed character ; and 
although from the similar geological characters of the two, 
many species were common to both, yet each had its own 
characteristic association. For example, ‘ Primrose Valley ’ — 
a rather unfortunate local name ; ‘ ravine ’ would be better — 
alone showed such species as Viola hirta. Polygala serpyllacea, 
Lychnis dioica, Hypericum pulchrum. Geranium sanguineum 
(profuse). Trifolium medium, Lathyrus montanus, Spireea 
Filipendula — quite the most abundant and luxuriant growth 
that one has yet seen anywhere of this species — Agrimonia 
Eupatoria, Poterium Sanguisorba and Rosa pimpinelli folia in 
one of its few stations in East Yorkshire. Epilobium hirsutum 
and Sium erectum grew respectively near or in the beck. On 
the slopes of the ravine, or in damp depressions thereof, were 
found Arctium minus, Serratula tinctoria, Centaurea nigra, 
Hieracium pilosella, Fraxinus excelsior — poor looking speci- 
mens for ash trees and all terribly infested by the ash canker — 
Scrophularia aquatica, Stachys Betonica, Ajuga reptans, occas- 
ionally with beautiful rose-purple flowers instead of the usual 
steel-blue ones, Habenaria viridis, Scilla festalis, several 
sedges including Car ex disticha, C.flacca and C. acutiformis with 
the two grasses Bromus giganteus and Brachypodium gracile. 
Two cryptogams Pteris aquilina (bracken) and the great 
Horsetail, Equisetum maximum may conclude an interesting 
but by no means exhaustive vegetal list of Primrose Valley. 
The plants of the Flat Cliff might be said to constitute 
one, or more correctly perhaps two, very full associations, 
including as it did such species as follow : — 
Ranunculus Drouetii, R. heterophyllus, R. Flammula, and 
in one pond now nearly dried up. Ranunculus Lingua (the 
first record for the locality of this fast diminishing species). To 
these may be added Hypericum quadratum, Ulex europceus. 
Primus spinosa— both of the last two species being low and
