In bieisies to Equisetum Telmateja, mentioned above, the 
tubers of E. sy/vaticum are ovoid and arranged so as to — 
tosary; but the structure agrees very well with that ° the 
preceding species, except that some layers of the bark-par- 
enchyma are strongly thickened so as to form a kind of ene 
tecting sheath around the central part of the tuber, whic 
peculiarity is, also, to be observed in the rhizome of this 
species. —THEo. Hobo.
