stems closely jointed, young stems distantly jointed, dull 

 brown when dry, usually branched from near the base, the 

 younger portion of the stem yellowish strigose; joints clothed 

 with boot-like sheaths I to 1.5 cm long or those along the 

 old stem withered down to a broad shallow cup, brown, 

 truncate at the apex or nearly so, yellowish brown strigose 

 especially toward the bristly top, submembranous. Leaves 

 alternate, well scattered, obovate or obovately elongated, sub- 

 membranous, spreading divaricately, flat, rich or deep green 

 above, much lighter beneath, curing nearly equally dull 

 1 jwn on both sides, entire, glabrate above, minutely puber- 

 ulent beneath or subglabrate, the average lamina 8 cm 

 long by 3.5 cm wide above the middle, apex bluntly pointed 

 and obtuse, base cuneate; petiole 1.25 to 2 cm long, deeply 

 caniculate along the upper side, short strigose beneath, ciliat^ 

 along the upper lateral margins; midrib puberulent on both 

 sides, darker brown beneath, slightly raised also on the up- 

 per side especially toward the base; lateral nerves 7 to 11 

 pairs although with secondary intervening ones along the 

 midrib, faint, asoendingly curved especially toward their distal 

 ends, cross bars and reticulations quite numerous and very 

 faint. Inflorescent spikes subterminal, erect, ascending, soli- 

 tary or 2 to 3- branched from the base where it is usually 

 subtended by small leaves, greatly varying from 1 to 3 dm 

 long or even longer, very slender and usually strict, curing 

 straw brown, sides fluted, puberulent, flower bearing from 

 below the middle; flowers usually only one in an thesis at 

 a time, odorless, light pink or roseus, erect, evenly scat- 

 tered except toward the base; nodal sheath 3 mm long, 

 brown, submembranous, truncate and obscurely pointed at 

 the top, the outer portion more prominently pointed, glab- 

 rous on the inner side, dull yellowish brown ciliate on the 

 outer side and along the upper edge; flowers 1 to 3 from 

 each joint, each nodal group alternating with the adjoining 

 ones; involucre surrounding the flowers brownish, more mem- 

 branous than the sheath, 1.5 to 2 mm long, glabrous, more 

 or less united below the middle or nearly free, the 3 to 5 

 lobes diverse in size and shape, usually oblongish, apex 

 acute to subtruncate, each segment with a midrib; pedicel
