parties. The Permian limestone tract towards Conisborough 

 yielded a characteristic set of plants, and sets quite as typical were 

 obtained in the district occupied by the Bunter pebble beds, in 

 the black boggy ground of the " Cars," and in the dykes draining 

 the " Cars." Some of the rarer plants observed were Thalidrum

Twenty-one species of mosses were collected, including 

 Barbula Hornscliuchiana and Pogonatum nanum. 



A few common Hepaticse and Lichens were collected. 



Among the fungi collected were Melanipsora populina, Tilletia 

 caries, Uredo Circece, and Trichobasis stiaveolens. 



Few Algse were collected, though no doubt this is a district 

 that would well repay working. Fragilaria capucina was very 

 abundant.
