BOTANICAL REPORT — 1878. II 



which may be mentioned Helleborits fcetidus, Berberis znilgaris, 

 Sedum reflexu7n, Sison aino)iiuin and Smyrnium olusatrum. 



Mosses and hchens though not luxuriant occurred in tolerable 

 numbers. 



The oxlip, Primula vulgaris /? caulescens was observed in two 

 or three places; in one apparently wild, with reddish flowers; in 

 two of the places at least it was noticed to be growing side by 

 side with both the primrose and the cowslip as if a hybrid between 

 those species. 



ILKLEY, MAY 25TH, 1 8 78. 



At the meeting on May 25th the localities explored were 

 Ilkley and neighbourhood, Otley, Rqmbald's Moor, Shipley, 

 Bolton Woods, the Strid, Skipton, the Washburn A'^alley, &c. 

 The number of flowering plants observed during the day was 

 large for the time of year, but many more would no doubt have 

 been found had the season been more advanced. The flora of 

 Wharfedale is of a mixed character, many plants of a limestone 

 type being associated with those usually found on the carboniferous 

 grits and shales; this is no doubt to be attributed to the large 

 number of limestone boulders present in the glacial beds by which 

 in the sides and bottom of the valley the millstone grit is 

 concealed. Bolton Woods yielded species characteristic of sub- 

 alpine Avoods, as Trollius europcv.us, Gerafiiu//i sylvaticum and 

 Crepis paludosa ; and Rombald's Moor those of mountain moors, 

 as Vacciniuin Vitis-Idcea and Empetrum nigru7n. Many aliens and 

 denizens occurred, as Hesperis matronalis, Geraniuvi phceu)n 

 and pyrenaicum, Dorotiiawi Pardalianches, Aconitum Napellus, 

 Saxifraga hypnoides, Peucedanuni Ostruthiuin and Amsiiickia 

 Lycopsoides. 



Mosses, except those of corticolous habit, were plentiful; 

 some being of a mountain type, as Atidrecea rupestris, 

 Racomitriuin aciculare and R. heterostichum. Saxicolous lichens 

 were plentiful, but corticolous kinds were scarce and stunted, as is 

 usually the case in the West Riding.
