Notes

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.
