Var. cruenta Spring (8 . erythropus Fée F il. Bras. 280, non
Spring) is a form with bright red stem and root-fibres. S. lliim -
holdtiana A. Br, in F il. Nov. Gran. 877, from the banks of the
Orinoco, is said to differ from sulcata by its more flaccid texture,
shorter base on the upper side of the leaves of the lower plane, and
lower side with a longer auricle.
