ALG/E. 



THE bulk of the following list of local Algae is compiled 

 from the ' Alga-Flora of Yorkshire ' : Transactions of the 

 Yorkshire Naturalists' Union, Parts 22, 23, 25, 27, igoo-01, by 

 W. West, F.L.S., and G. S. West, B.A., A.R.C.S. 



Messrs. W T . West and sons have visited the parish on 

 many occasions to collect algae, etc., mostly in Crimsworth 

 Dean, Cragg Vale towards Blackstone Edge, Ogden Clough, 

 Greetland, and Fixby. 



Very little has been done in this branch by resident botan- 

 ists. The late Thos. Carnell occasionally made collections. 

 Some years ago the writer made a number of sketches of 

 Desmids, Diatoms, etc., collected in the spring-water pond 

 near Park Gate Farm, Southowram, and other places ; these 

 have been verified by Messrs. W. West and R. H. Philip. 



When the number of springs in all parts of the parish is 

 taken into account, along with the numerous moorland bogs 

 and swamps, the Alga-Flora would prove a very rich one if 

 thoroughly worked out. 



The sign ! denotes that the species has been met with by 

 the writer. In all other cases, where not specially noted, the 

 records are by the Messrs. West.
