 keeled, dorsal surface granulate and transversely ridged with more or less distinct rows of 

 tubercles, ventral surfaces with approximate narrow diagonally transverse ridges; scar lateral, 

 excavated, lanceolate, about one-third the length of the nutlet.

 stricted near the apex, armed along the keels and in the spaces between the firm subulate 

 glochidiate prickles, transverse ridges absent ; scar deep, broadly flanked, ovate or deltoid.

 simple Lower leaves linear to linear-oblanceolate, acute, 1-2 cm. long, strigose on both sides 

 but more thinly on the upper ; racemes elongated, loosely flowered, the lower flowers bracteate ; 

 corolla shorter than the calyx, about 1 mm. broad ; calyx conspicuously bristly with ascending 

 or somewhat appressed bristles, lobes strongly accrescent, becoming 5-6 mm long; nutlets 

 broadly ovoid, 2 mm. long, dorsal side obscurely ridged on the median line, densely covered with 

 bristles, these armed their whole length with divaricate barbs and joined at their bases by ridges, 

 interspaces granulate, ventral side keeled and obliquely rugulose but not bristly; scar sunken, 

 ovate, half as long as the nutlet.

 dorsal side reticulate with thin ridges, keel and ridges armed with minutely barbed subulate 

 spines, interspaces tuberculate ; ventral side distinctly keeled from the large ovate or deltoid
