order named. Alopecurus grows in caespitose clumps 3-6 inches 
in diameter. These tufts are the nucleus for the growth of such 
plants as Epilobium Hornmannit Reich., Agrostis hiemalis, and 
Veronica serpyllifolia L. Following the establishment of these 
herbs come Carex vartabilis, C. lanuginosa Michx., C. festiva Dewey,
