NDER the name of Spongodendron , Zanardini 1 established 
in 1878 a genus of Siphoneae from specimens collected 
by Dr. Beccari in New Guinea. In the course of the work 
of one of us at the above group, it became necessary to see 
specimens or drawings of this type which should give more 
information than the short description in the Nuovo Giornale. 
On applying to Dr. Beccari, he at once with the greatest 
kindness and courtesy sent specimens of the two species 
N. crassum and N. dichotomum described by Zanardini. On 
examination they proved to belong to the remarkable genus 
Spongocladia of Areschoug, described by him in 1853 2 . Only 
one species of this genus, N. vaucheriaeformis , has been re- 
corded hitherto, and specimens of it collected at Mauritius 
(whence Areschoug’s material came) by Col. Pike are in 
the herbaria of the British Museum and Kew. Spongocladia 
can hardly be said to be siphoneous, and so it follows that
