Fig .—E. B. 929 .—Flo. Dan. 1184.— Bolt. ZS.- 
Des. — Root much creeping, with scattered fibres. Stem erect, 
quite smooth, striated but not channelled, generally naked, but 
sometimes putting out a few branches late in the season, which are 
smooth, simple, and ascending. Catkin terminal, broad and short, 
for the most part sessile in the upper sheath. Sheaths short, close 
pressed to the stem, with very numerous short brown teeth. 
Often confounded with Equisetum Palustre,. of. which by some of the older 
Botanists it was considered only a variety. It is, however, very distinct, and 
may easily be distinguished by not bearing branches till late in the season, 
after the catkin has decayed ; its branches also are , less numerous, shorter, 
and either scattered over the plant or in irregular whorls ; it has shorter and 
more numerously toothed sheaths, which are pressed close to the stem. The 
whole plant is smoother, and has shorter, thicker, and nearly sessile catkins.
