8 THE AMERICAN MIDLAND NATURALIST 



high, 4111m. wide near the top and gradually becoming narrower 

 toward the base, as long as the calyx or even shorter. Seeds 

 black, "silvery" dotted. Leaves and flowers retain their natural 

 colors in drying. 



In ditches with the subsurface clay bare; Leeds (extinct in 

 the type locality, but in 1916, August 28, found in another ditch, 

 not far frcm the original spot). 



Its nearest ally, .4. aspera, is a larger plant, 30 60mm. high, 

 fastigiately branched, with its lower branches longer than the upper, 

 flowers opposite or alternate in the axils of the leaves, calyx teeth 

 triangular-ovate, about 1-2 as long as the tube, corolla about 2.5 

 cm. long, deep purple, capsule ellipsoid, about 10mm. high, almost 

 twice as long as the calyx, the herbage blackened in drying, and it 

 is a plant of the dry plains and hills. 



On August 19, 191 5 Dr. Edw. L. Greene, accompanied by 

 the writer, had a short buggy ride in the country adjoining Leeds. 

 He was too weak to leave his seat, and whenever some plants 

 attracted his attention, I went for them and dug them up. The 

 last plant we made an effort to locate was the one just described. 

 One or two years earlier I had found it in a ditch, but since then some 

 rural nature mender had made a pasture of the plot, and the ditch 

 had ceased to be a refuge for this plant. It was now extinct, and 

 later in the day Dr. Greene was too tired to look for it in my 

 herbarium. He insisted that .4. aspera grows only in dry, elevated 

 ground, never in ditches, and that this must be a distinct species. 



The foregoing statement I trust will serve as a reasonable 

 explanation why it happened that the plant here described was 

 named in his honor, it being the last one the beloved, immortal 

 master looked for during his last visit to his floral realm.
