10. Lycopodites.—Leaves linear, or setaceous, without ribs, or traversed by a single rib, inserted all round the stem, or in a double row.

This genus is subdivided into four sections, as follow:—

a. Leaves narrow, lanceolate, inserted in a regular manner all round a stem having the characters of Sagenaria.
