LOCAL FLORA NOTES VIII 



Albany County 

 Andropogon scoparius Michx. 

 On the sand plains west of Albany, this is one of the most abun- 

 dant of the grasses. Three forms are easily distinguished in the field, 

 but when dried and mounted they lose much of their distinctiveness. 

 The literature at hand does not indicate that they have been 

 formally recognized as varieties, nor is it my intention to do so here, 

 but merely to call attention to the characters which are most marked 

 in the field. 



a The most abundant form. Nearly or quite glabrous, the culms 

 purplish, sheaths green, sometimes with a rathgr sparse and spread- 

 ing soft white pubescence toward the top of the sheath. Culms 

 strictly erect. 



b Culms strictly erect, averaging from 4 to 12 inches taller 

 than a, when growing with it, purplish and conspicuously glaucous 

 beneath the nodes ; leaves relatively shorter and broader than a, the 

 lower and middle ones one-fourth of an inch wide and from 5 

 to 7 inches long, light green above, conspicuously glaucous 

 beneath and on the sheaths, somewhat more noticeably scabrous on 

 the margins and on the midvein beneath than in a ; sheaths copiously 

 pubescent with soft white spreading hairs, especially toward the top 

 of the sheath ; pubescence of the inflorescence more copious than in a, 

 but not longer. 



c Stems quite markedly decumbent at the base, and averaging 

 from a few inches to nearly a foot shorter than those of a, when 

 growing with it ; leaves about as narrow as a, but the sheaths very 

 copiously pubescent, especially toward the top of the sheaths with 

 conspicuously spreading white hairs which are somewhat stiflfer than 

 those of the same parts on either a or b. Color of the culms and 

 leaves practically the same as a ; no glaucous tint noticeable.
