This division is characterized by the dense ramuli aggregated 

 on botli sides of the main branches. Morphologically speaking, 

 the segments corresponding to the pinnae as well as to the pin- 

 nules of the Officinales are stunted in the present group, forming 

 a sort of " kurztrieb," The simpler form suggests close affinity 

 with the preceding section and there can be no sharp line drawn 

 between the two. Corallina Cuvieri var. calUftera, Cor. rosea, 

 etc., of this section are closely related to Cor. Berterii of the 

 preceding section. Some vexatious and erroneous references, as a 

 consequence, have been made in the genus. For example, Jania 

 granifera Sond. was taken by Areschoug^^ as synonymous with 

 Cor. Cuvieri Lamx. ; Kutzing'^ transferred the former to the 

 genus Corallina keeping the original specific name : finally Coral- 

 lina granifera KiJTZ. was referred by Hauck'^' to Cor. officinalis 

 L. Consequently, if these referrences have all been correctly 

 made, Cor. Cuvieri Lamx. must be united with Cor. officinalis L., 

 or at least there must be a close similarity between both species, 

 which can not be readily admitted.
