LESKEACEAE 207 



easily seen and wide-spreading, and arc a rather dark 

 yellowish-green. 



Both species of Helodium are to be expected only in 

 very wet places, and both have small leaves. The erect, 

 close growth of //. lanatum, with stout stems regularly 

 pinnate, and the thin, straggling mats of //. paludosum, 

 with prostrate, slender stems and distant branches, are 

 distinguishing characteristics.
