This plant altogether resembles P. polyatachyos, var. laxijiora, except that its 

 spikelets (glumes and nuts) are larger and brighter.

This and tlie preceding 4 species may be treated as extreme forms of P. poly- 

 stachyos, Benuv. P. Hildehrandtii, with its strong development and compound 

 Umbel, yet with excessively narrow spikelets and capillary rays, appears as distinct 

 as any of the preceding 4.

 Umbel 1-6 in. in diam., simple or compound, or one compound head ; 

 bracts 3-5, lowest overtopping the inflorescence, similar to the leaves.
