glandular calyx-lobes; with us, the red choke-berry does not succeed 

 well in cultivation in the open, seldom becoming over four feet high, 

 and not appearing anything like as vigorous as A. atropurpurea 

 when growing alongside of it; the red fruits persist on the shrub well 

 into the winter. The third species, Aronia nielanocarpa, the black 

 choke-berry, dififers from both the others in having glabrous leaves, 

 twigs, and cymes, and its black or nearly black fruit, a quarter to a 

 third of an inch in diameter, falls in the autumn; its stems and 

 branches are nearly straight and upright. 



The foregoing obsen^ations upon these shrubs have been made 

 from plants in the fruticetum of the New York Botanical Garden. 

 The plants from which our illustrations were obtained were grown 

 from seed collected on Staten Island, New York, in 1896, near the 

 type locality at Tottenville.
