ON CYPERACEX 241 
had the same experience at Bremen. Bubdk experimentally demonstrated 
the truth of the suspicion (Gisterr. Bot. Zeitschr. 1898, xlviii. 14). 
The teleutospores were first found, in this country, on Scirpus lacustris 
floating down the river Ouse at King’s Lynn, Nov. 17, 1877. The plants 
had evidently been cut on that river or one of its tributaries, but it 
was not till 1894 that the teleutospores were found in situ near Earith, 
Huntingdonshire ; and a visit to the Old Bedford Level at that place, 
in July, 1895, revealed the zecidia in abundance. See Gard. Chron. (/. ¢.). 
DistrisuTion: Europe generally; a similar ecidium on 
Limnanthemum indicum has been found in Queensland, but no 
teleutospores have yet been found there.
