Stem erect, slender, rather flexuose, about 2 feet high; leaves a span long, linear, smooth, 
doubled up without revolute margins, in whorls of three, except at the lowest node of each 
shoot, where they are opposite—internodes 2” or more long, each with one or more slim and 
densely-leaved branchlets, giving it a comose appearance. Umbels 2-3 in each of the upper 
whorls, scarcely half the length of the leaf, with pedicels half the length of the peduncles, and, 
together with the involucral bracts, somewhat tomentose. Stipe of the staminal crown, about 
the length of its lobes, claws cultriform, erect, as high as the white tips of the connectives.
