 floribus paullulo majoribiis recedit. 



Habit of the species, 20-25 cm. high. Leaves crowded, imbri- 

 cate, subsessile or very shortly petiolate ; leaflets linear, cuneate, 

 shortly acuminate, 10-30 mm. long, 1-2-5 mm. broad, relatively 

 thin in texture, the older leaves covered sparingly with appressed 

 silky golden hairs, the younger fulvously sericeous." Spike terminal, 

 cylindric or subhemispherical, 6-15-flowered. Calyx fulvously 



* The indumentum is probably always silvery in living specimens.
