Has. Mexico, Henke.—The habit of this plant is so en- 
tirely similar to that of Helminthostachys dulcis of Kaulfuss, 
that we should almost have considered the two as identical, 
were it not that the author figures and describes the capsules 
as pedicellate and solitary, and crowned with a four-lobed 
appendage, instead of having them combined in a whorl be- 
neath a lobed and peltate scale with which they are united. 
"We have seen no specimen, and therefore retain the genus; 
adopting with Presl's character.

differing not only in fructification, but remarkably so in its 
habit. It is exclusively an Asiatic plant, unless, as we suspect, 
the Botryopteris of Presl should prove the same. It is proper 
to mention, that the figure of the fructification given by 
‘Kaulfuss (Zn. Fil. t. 1. f. 1.) is incorrect; pince 
having been omitted.
