everywhere glabrous; it has a similar root, but with smaller 

 tubers; stems branching, erect, bare at the base; at first the lower 

 leaves are only 1 line long, increasing upwards to a length of 4 

 lines, are shortly subulate, spreading, cuspidate at the apex, rigid, 

 5-nerved; the inflorescence is capitate, sericeo-tomentose ; calycle 

 concave, acute, half the length of the tube of the corolla.

A low-growing, suffruticose species, with few branching erect 



stems 3 in. high, bare at the base, very glabrous ; lower leaves 



barely 1 line long, increasing upwards to a length of 6 lines, and 



J line broad, linear, sub falcate, channelled, 3-nerved; inflorescence

lous outside ; tube extremely slender, 5 lines long ; segments
