(EQUISETUM ARVENSE Linn., which has the fertile stem 
simple, herbaceous, and evanescent, and the barren stem 
annual and very much branched in regular whorls, is in- 
cluded by Kuhn {Fil. Afr. 181) from the Cape (Bergius). It 
is not known at the Cape, nor is it known at Kew as a Cape 
plant, and is probably a mistake.)
