to be intermediate between the two species. Professor 
Wille originally determined the species he observed 
to be V. prcemorsnm, and professor Nordstedt confirmed 
the determination. I have seen a great many speci- 
mens of it. and I am inclined to regard it as a separate 
variety.

Professor Nordstedt writes further: 
»Ehuru denne växt mycket afviker frân den vanliga 
Char a aspera har jag icke ansett mig att kunna uppställa 
den som egen art utan tillsvidare endast som en form. 
Möjligen kan den vid odling öfverga i en mera vanlig 
form». 
»Af Char a fragilis hunes en temligen, dock ej füllt 
analog form, v. Sturrockii J. & H. Groves, som jag sjelf 
sett i Skottland. Char a dissoluta A. Br., som i vissa af- 
seenden visar likheter, misstänkes af Hera förff. endast 
vara en form af en annan art» 1 .

Although this plant differs conspicuoush r from the common Chara 
aspera I have not thought it right to introduce the plant as a 
separate species, but preliminarily only as a form. Perhaps it may 
change into a more common form when cultivated. 
Of Chara fragilis exists a somewhat, but not quite, analogous 
form, the var. Sturrockii J. & H. Groves, which I have seen in Scot- 
land. Chara dissoluta A. Br. which in some respects shows simil- 
arities, is suspected by a number of authors to be only a form of 
another species.
