Slender, tuberous, deciduous perennial herb up to 43 cm tall. Stem:
tuber compressed globose to rhizomatous, 2 - 2.4 x 1 - 1.5 cm; stolon

HABITAT. Unknown. Hapaline ellipticifolia
is close in appearance to H. benthamiana
and differing in the shape of the ovary (bottle-shaped versus ovoid)
and leaf blade outline (elliptic versus sagittate). The Kurz 268
collection cited above (see also Kurz 1873: pl.9) has long been
assumed to belong to H. benthamiana.
However, the Kurz collection has a leaf blade with parallel posterior
lobes and bottle-shaped ovaries.
