125. PHARUS L. 



Spikelets in pairs, appressed along 

 the slender spreading, nearly simple 

 panicle branches, one pistillate, sub- 

 sessile, the other staminate, pediceled, 

 much smaller than the pistillate spike- 

 let; fertile lemma subindurate, terete, 

 clothed, at least toward the beaked 

 apex, with thick uncinate hairs; 

 blades petioled (the petiole with a 

 single twist reversing the upper and 

 under surfaces of the blade), the 

 nerves running from midnerve to mar- 

 gin, with fine transverse veins be- 



tween the nerves. Perennials with 

 broad flat elliptic or oblanceolate 

 blades and terminal panicles with 

 rather few stiffly spreading branches 

 breaking readily at maturity, the 

 terete pistillate spikelets appressed, 

 the uncinate fruits acting like burs. 

 Type species, Pharus latifolius L. 

 Name from Greek pharos, cloth or 

 mantle, possibly alluding to the broad 

 blades. 



1. Pharus parvifolius Nash. (Fig. 

 819.) Culms long-decumbent and 

 rooting at base, the flowering shoot 

 30 to 50 cm. tall; blades elliptic,
