Paramapania longirostris


Leaves narrowly linear, flat, very gradually narrowed into a flagelliform, curved to circinnate, aculeate-scabrous point, scabrous on the margins and keel at least in the upper half, pale green or glaucescent, 30-65 cm by 4-6 mm; Inflorescence simple, with up to 4 spikelets, usually consisting of a single spikelet; Flowers 2½-3 mm long; Stamens 2.


Asia-Tropical: New Guinea present, Dallman present, Idenburg R present, NE. New Guinea present, Nabire present, Sepik region present, Sorong present, W. New Guinea present
Malesia: New Guinea (W. New Guinea: Sorong; Idenburg R.; Dallman, Nabire; NE. New Guinea: Sepik region).


Very similar in habit to P. gracillima, but readily distinguishable by the quite different shape of the nut.
P. attenuata S. T. BLAKE is said to differ from P. longirostris by the twice as long glumes, the flowers slightly shorter than the glumes, and the indistinctly 3-angled (not 6-angled) nut passing gradually (not abruptly) into the relatively shorter beak. However, “glumae. 1,5 mm longae” in UITTIEN's description of P. rostrata UITTIEN (1935, l.c.) is obviously an error for 2.5 mm. The young nuts in the type collection of P. attenuata (BRASS 12930) do not differ from those of P. longirostris.
