tnjophora Oerstedi J. Ag. mscr. Genus novum«. The fact that 

 J. Agardh wrote on this certainly the original label Botryophora 

 Oerstedi is rather remarkable, as at the same time on the speci- 

 mens he kept back in 

 his own herbarium he 

 has written as already 

 pointed out by M. A. 

 Howe »Batophora Oer- 

 stedu and it is rather

 he (1. c. 1887, p. 139) 

 writes : »Antea quam

 he does not mention at all the name Batophora, as just this 

 name is to be found on his own specimens. However this may 

 be, I think it is necessary in ac- 

 cordance with the laws of priority 

 to call the genus Batophora in 

 agreement with Dr. Howe. 



In Bulletin Torr. Bot. Club, 

 Vol. 31, 1904, p. 95, Howe has 

 described a new variety of this 

 species which he has called var. 

 laxiis ; it is said to be specially 

 distinguished by its open, loose 

 structure and by having the spor- 

 angia obovoid, oblong — elhpsoid 

 or pyriform in shape. Later on 

 Howe has himself (1. c. 1905,

good reason, l^or one reason the ^ ' 



original material has just this loose habit, also we find all 



possible intermediate forms. Even in the same locality (Krause's 



Lagoon in St. Croix) I have found not only the already mentioned 



forms of the sporangia but also spherical and a little fiat- 



tened forms as Harvey figures them. The accompanying Fig. 60
