144 Rhodora [JULY 
together, the upper strongly ascending, all slightly irregular and not 
running straight to the margin; mature petioles 15-20 mm. long: 
racemes many flowered, mostly lateral, short, dense, erect, glabrous, 
3-5 em. long; lower pedicels 8-17 mm. long, in fruit 10-25 mm. long: 
flowers small or of medium size: petals from oblong to narrowly 
oblong, 7-15 mm. long: hypanthium open saucer-shaped, very rarely 
slightly woolly, 3-4 mm. in diameter, constricted below on the young 
fruit: sepals short, triangular or lanceolate, 1.5-2.5 mm. long, re- 
curved from the middle when the petals fall, slightly woolly inside: 
summit of the ovary woolly, becoming almost glabrate in fruit: 
mature fruit almost black, glaucous. Fies. 3 A-G. 
Related to A. sanguinea in its narrow and often long petals, but dif- 
fering in the blunter leaves with veins which do not reach the margin, 
fewer teeth of a different shape, shorter erect racemes with the flowers 
on shorter pedicels, and the more glabrous character of the whole 
plant. Closely related to A. humilis in the venation of the leaves and 
in general appearance, but differing in narrower, often longer, petals, 
blunter leaves, usually sharper teeth, and much earlier loss of to- 
tentum.
