When well-developed, var. filiforme is distinctive, with filiform julaceous stems and straight leaves. There are variants with somewhat falcate-secund leaves that can be confused with H. andoi. The latter species has long-attenuate leaf apices, is not julaceous, although filiform, and the leaves are not strongly imbricate as in var. filiforme. The many specimens that closely resemble var. filiforme strongly suggest that it may be an environmental form induced by the habitat that holds moisture rather briefly during the growing season.
