e. Hydnophytum zippelianum Becc.

Hydnophytum zippelianum Becc (1885) 174, t. 54: 8–11. — Type: Zippelius s.n. (L), New Guinea?

Base tuberous? Leaves lanceolate-elliptic, 8 by 2.1 cm, apex and base attenuate-acute, petiole 0.6–0.9 cm. Inflorescence sessile in axils. Corolla lobes long. Flower illustrated in Beccari (1885: t. 54).

Ecology & Habitat — Unknown.

Note — Type locality uncertain, possibly New Guinea. This species is illustrated by Beccari, and we have seen the Zippel collection, however, since the locality is dubious, and it equates to no other species, we have left it as little known. Interestingly H. stenophyllum, H. virgatum and H. sp.1, three other little known species share the combination of narrow leaf and sessile or shortly pedunculate inflorescence.
