In most species many of these buds, which alternate with the leaves, remain dormant, but in others the aerial shoots are copiously and repeatedly branched.
They derive this moisture from the air by means of aerial roots, developed from the stem and bearing an outer spongy structure, or velamen, consisting of empty cells kept open by spiral thickenings in the wall; this sponge-like tissue absorbs dew and rain and condenses the moisture of the air and passes it on to the internal tissues.
Open aerial longdistance lines have also been loaded, but not to the same extent.
They are grass-like herbs, sometimes annual, but more often persist by means of an underground stem from which spring erect solitary or clustered, generally three-sided aerial stems, with leaves in three rows.
