In two plates are excellent figures of additions to British lists, 

 viz. on pi. 391 Chara aspera, Willd., subsp. nova desmacantha 

 (characterised by spine-cells in groups of three to five, instead of 

 solitary or in pairs, and by more numerous cortical nodes, there 

 being usually from fourteen to eighteen instead of from ten to twelve 

 to each internode), and on pi. 392 Nitdla hyalina, Agardh. (dis- 

 tinguished from all other species found in Britain by bearing secondary 

 branchlets, usually one above and one below each primary branchlet). 

 The Chara has been found in several localities in England, and is 

 the prevalent form of C. aspcra in Ireland, and it occurs also in 

 Sweden and Bavaria. The Nitella is as yet known as British with 

 certainty only from The Loe, near Helston, in West Cornwall ; but 

 it occurs almost throughout Europe, and in Africa, Asia, Australasia, 

 and North America. Both plants should be looked for in Scotland.
