ember 1920, writes as follows: — "This represents an im- 

 portant extension of the range of the species in the British 

 Isles. It is a form Avith unusually short branchlets. The 

 fruits, of which very few are developed, are shorter and 

 broader than in other British forms." On 2nd August 

 1920, when in compan}- with Dr. G. Claridge Druce, and 

 searching for specimens of Chara baltica, Bruzel, for 

 him, I raked up plants of C. CANESCENS, Linn., and 

 ToLYPELLA NIDIFICA, Leonluirdi, which Dr. Druce pre- 

 served ; but, not being aware at the time what they were, 

 I did not preserve specimens of them myself, and it was 

 only after Dr. Druce's specimens had been identified by 

 Mr. James Groves that I knew what their names were, 

 and that both of them were new records for H. C, Watson's 

 county No. Ill Orkney, as published by Dr. Druce in 

 '• Bot. Exch. Club Secretar^^'s Report for 1919," Addenda 

 1920, p. 730 (October 1920). 



ToLYPELLA NIDIFICA, Leonlairdi {fide James Groves). — 

 Mud at bottom of brackish water, 5 feet deep, in a loch 

 at sea-level, near the noiist for boats. Nether Bigging, 

 Loch of Stenness, Stenness, Mainland, 2nd August 1920, 

 G. 0. Druce; and 14th September 1920, H. H. Johnston. 

 Native. Common. Plants in fructitication. My largest 

 specimen measures 16 inches (40 cm.) in length. With 

 reference to my specimens, Mr James Groves, in a note 

 dated 18th November 1920, writes as follows: — "The first 

 record of the plant for Britain. I have little doubt that 

 the ToLYPELLA collected in Orkney by Mr. A. H. Evans, 

 and recorded as T. glomerata, Leonhardi, belonged to this 

 species, but the specimens had only small unripe fruit." 

 Mr. A. H. Evans collected his specimens in the Loch of 

 Stenness in 1911. A new record for H. C. Watson's county 

 No. Ill Orkney, published by Dr. G. C. Druce in "Bot. 

 Exch. Club Secretary's Report for 1919," Addenda 1920, 

 p. 730 (October 1920).
