Stems six to eight inches long, erect or sub-erect, or 
procumbent and rooting at the base, and continuous and 
ascending toward the point. Green portion pinnately and 
repeatedly much branched. Leaves of two kinds, the smaller 
above on the stems and under on the spikes. Larger leaves 
one line long, rather distant on the main stem, close on the 
branches, acute, oblique, serrulate on the upper edge, over- 
lapping; small leaves shorter, pointed. Spikes one-third inch 
long, terminal on the branchlets, with the smaller bracts on 
the same plane as the larger leaves, i.e. below. This was 
referred to but not identified in our first edition, page 262.

Genus 59. Isoetes Linn. 
Small rush-like plants, having a small bulbous crown from 
which rise numerous narrow linear-pointed leaves, one to four 
inches long, containing four air tubes, and with frequent 
transverse partitions. The leaves widen and thicken at the 
base, and in their axils somewhat sunk into the base of 
the leaf, and often partly covered by its epidermis, is to be 
found the single sporangium. Sporangia one-celled, those 
in the axils of the outer leaves containing a few large re- 
productive spores, those in the axils of the inner leaves the 
numerous minute microspores. 
The genus has no outward resemblance to Selaginella,
