Stem 20 — 30 cm high with short internodes of equal length richly branched, 

 in each leaf-axil only one branch with very short internodes, secondary branches 

 wanting. Stem-/eaves linear, ± 1 mm broad, fragile, lacunous (no whole stem-leaves 

 are preserved on the material and the basal leaves are quite wanting) with sheaths 

 15 mm in length or somewhat longer in the lower part. Branch-leaves linear, short, 

 50—60 mm, 3-nerved, the lateral nerves running in the very margin as in P. filifor- 

 mis, apex roundly obtuse; sheaths of the branch-leaves brown, short. Young ligu-

 5 — 7 cm. Spike of 5 — 6 (or possibly more) whorls, the basal one a little retired, the 

 others more approached to each other, the whole ca. 30 mm in length. Pollen and
