Salicornia dolichostachya, Moss, in Scotland.

Up to the present no record of Salicornia dolichostachya,. 

 Moss, has been made for Scotland, although the species 

 occurs in Denmark. When visiting the salt marsh near 

 Gullane, however, with Section K of the British Associa- 

 tion (September 1921) this sj)ecies was found by the writer 

 growing in its normal habitat, namely, near the seaward 

 limit of the salt marsh. In the higher parts Salicornia 

 herbacea occurred in some quantity, both the forvia 

 stricta and the forma patula being present, though the first 

 named was by far the more abundant. 



The plants of Salicornia dolichostachya were quite 

 typical, exhibiting tlie long, blunt, tapering spikes in which 

 the lateral flowers are almost or completely separated by 

 the central one. In one specimen a very rare and interest- 

 ing abnormality occurred, the partial dichasium consisting 

 of four in place of three flowers. The supernumerary 

 flower was centi-al in position, so that two superposed 

 flowers completely separated the lateral ones. In several 

 specimens the accessory spikes, which ai"e so characteristic 

 of this species, were present. They arise from below and 

 at the base of the sterile segments of the main lateral 

 spikes. 



As might be expected from the presence of both S. 

 herbacea and S. clolicJi,ostachya, a few intermediates occurred, 

 which probably represented hybrid offspring, and in which 

 the central flower did not separate the lateral ones.
