I UTE 
ON. THE NARDOO. PLANT. OF AUSTRALIA. 
At the meetings of the Society of Germa Naturalists and Physi- 
cians held at Stettin, Professor Alexander pi exhibited living spe- 
cimens of four species of Marsilea, two of which (M. hirsuta, R. Brown, 
and M. salvatrie, Hanstn.) had been raised from seed received from 
New ‘Holland, and are éalled ** Nardoo” by the natives. Professor 
Braun does not agree with Mr. Currey (supra, p. 161) in regarding M. 
salvatrie aud M. macropus, Hook., identical. He thinks M. salvatriz 
undoubtedly distinct from M. macropus, but most probably identical 
with M. Muelleri, A. Braun,—a species of which only sterile specimens 
had been described. Moreover, the name M. macropus, given by Hooker 
in 1854, cannot stand, as the species to which it applies had been 
named, two years previously (in 1852), M. Drummondii by A. Braun. 
Professor A. Braun added that thirty-eight species of Marsilea were 
^ present known, all of which had a very limited geographical distri- 
ution. in 
CHROOLEPUS LAGENIFERUM, Hildebrand. 
This Alga is of a yellow colour, and was probably introduced from 
the tropics. It was noticed a few years ago by Dr. Hildebrand in the 
hothouses of the Bonn Gardens, but lately also in those of Dresden and 
Berlin, where Palms and Orchids are cultivated.
