Slender, hirsute or hispid annuals, 'with narrow entire alternate leetyes 

 andbraetless (sometimes leafy-bracteate below) flowers in slender, spikes^ or 

 racemes. Calyx more, i or less hispid, closely embracing the fruit and de- 

 ciduous with it. .Corolla small, often inconspicuous. Nutlets, 4, or by abor- 

 tion fewer, attached from the base upward usually nearly fp the apex, smooth, 

 muriculate or tuberculate, sometimes with a slight dorsal ridge, the margin 

 ^pmetimes acute or even winged. — Krynitekia Fiseh. & Mey. in part.

 hispid throughout, closely and, intricately- branched from the base up, the 

 whole forming a subsphei&il mass" 2— 4 dm. in' diameter: leaves small, nu- 

 Hierous, linear,,, the hairs wjtl^ pus,tul3,te .baise: spikies uniserial, crp;<yded, the

 iculately branched, frpii near the base, rather rigid, 2-3 dm. high: leaves 

 linear, 2-4 Cm. long: spikes slender, braoteate at base: sepals narrowly linear

* Besid^ the species described, several other^ are occasibnctlly reported from our range, 

 among which may be named C. aifinisi ' C Torfeyana. 'C ambigua, etc. It Seems doubtiul 

 w lether these ^cies occur in our range. FuHy developed material with mature niitlets is 

 li elv *o show that those so reported belong to one or the other of the species 'h'ere de-
