Sion where Rion gathered the original specimens the plant has 
ee ae disappeared or been destroyed, but grows plentifully 
ween Guercet and Charrat (Favre, 1883), and near Saillon and 
Siders (ex Gremli, Swiss Flora, p. 54, transl. Paileon, 1889)—all 
in the canton of Valai ais. In Herb. Kew. are aut entic specimens 
and from pools at the Chateau Neuf near Sion, at 600 metres (ex 
herb. Joad); also examples gathered by Brunet (1861). The 
Transylvanian plant has pilose achenes, but Simonkai has seen in 
herb. ur an example from Nagy-Szeben, in the county of 
Szilagy, with glabrous achenes. In all Lagger’ s authentic speci- 
mens, including those mentioned above, the achenes are glabrous, 
but in the original description he does not state whether they are 
glabrous or pilose. In herb. Simonkai are Swiss examples with 
pilose achenes. In Joad’s examples in Herb. Kew. the plant 
beari l 
fruit the achenes are quite glabrous. In Lower Austria it is found 
in lakes on the Nimmersatteiche, near Peldeberg a and 
below the Manhartsberg at 200 metres above sea-level (Dr. Wester- 
leithigen in Herb. Kew.,—achenes stiffly pilose, with leaves some- 
what darker). It is the R. circinatus of Baumgarten, Fuss, and 
Go pehlan de amples “med stand. kortare in pist.” (with stamens 
shorter hate the pistils—which cannot apply to any other form).

These two varieties are distinguished from the others in having 
the stamens shorter than the pistils.
