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.
