 Kjellman, F. R., Om Floridé-slagtet Galaxaura, p. 49. 



Of this plant I have only seen the original material which 

 is now kept in Herb. Kjellman in the Botanical Museum in 

 Upsala ; it was collected at St. Thomas and distributed by P. T. 

 Cleve. 



The original material consists of numerous mostly small pieces. 



Kjellman points out that the most characteristic feature of this 



species is that the filaments in the medullary tissue differ very much 



in thickness, and that the supporting cells are often not developed, 



the assimilating filaments in this case growing directly out from 



the medullary filaments. The short 

 assimilating filaments often consist of 

 two cells only. The long assimilating 

 filaments are about 15 n broad and 

 have comparatively short cells, V-j^ — 2 

 times as long as broad. 



Kjellman supposes that the plant 

 forms low tufts pressed to the sub- 

 stratum.

Kjellman does not give any description or figures of this 

 old species of Solander but refers to the description of J. Agardh 

 in Epicrisis and to the figures of Ellis and Solander, p. 115, 

 tab. 22, fig. 3, and of Kützing in Tabulæ Phycologicæ, vol. VIII, 

 tab. 33, fig. 1. But on the other hand, when describing several 

 new species related to or formerly considered as forms of G. ru- 

 gosa, he points out in what way they differ from this species. 



The specimens which I refer to G. rugosa (Fig. 105) are cer- 

 tainly very like those I refer to the following species, on the other
