4-12 cm. X 1-4 mm. Peduncles axillary, erect to strict-ascending, 

 much surpassing the leaves, terete below, channeled above, cinereous 

 above, densely woolly below, numerous, 5-25 cm. high. Sj^ikes 

 erect, thin, with the flowers scattered or in false pairs and clusters. 

 Bracts closely subtending the flowers, erect or nearly so, typically 

 one half surpassing the calyx, herbaceous, saccate, triangular- 

 lanceolate, margins narrowly scarious, apex strictly acute, about 

 2.5 mm. long. Flowers apparently perfect. Calyx glabrous, its 

 divisions inequilateral, with the scarious margins distinctly wider 

 than the herbaceous midrib, apex obtuse, equaling the width of 

 the bract. Corolla very minute, forming incompletely closed beak, 

 with throat short, its lobes triangular, entire, acute, about 0.5 mm. 

 long. Stamens 2, included. Pyxis more than one third surpass- 

 ing calyx, ovoid-oblong, obtusish, circumscissile at about the lower 

 third. Seeds four, obscurely pitted, very dark brown, oblong, 

 1.8 mm. (or a little less) x 0.33 mm. 



This subspecies intergrades strongly with woodland or other- 

 wise sheltered individuals of the typical form.
