R. Paulas Tausch. ‘‘Caule repente cespititio, foliis omnibus 
emersis petiolatis vaginantibus decompositis linearibus, carpellis 
minutis glabris in spicam oblongam dispositis.” fe is the plant 
figured in Jean Bauhin, Hist. Plant. iii. 781, f. 2 (1651); as may 
be noted, the wavy lines loneoouaiite water are not seen in the 
woodcut, showing that it is the Jand-form that is represented, as 
Tausch also says “ foliis emersis.’ 
R. minutus Déll. Subsequently in the author’s later Fl. d. 
Baden, p. 1337 (1862), he reduced y to R. Be thee var. succulentus 
Koch, giving as a synonym R. cespitosus Thuill. It therefore 
does not differ from the plants depended by the two previous 
names.

differs from KR. trichophyllus and R. Drouetii in the short mid 
leaf-segments, the very small petals, and the subglobose carpels.

From the characters I do not see in what way this plant differs 
from R. divaricatus var. eradicatus, which is an earlier nam 
(1842) than confervoides (1845). ‘Folia longius petiolata”’ is 
sep sat “cee as a differential character. It occurred with 
confervoides in the Limingo district of Finnland.
