A. intermedia Spach. (?) — An Amelanchier collected in 1920 in 
an open bog at Ward Pond, Becket, was sent to Professor Wiegand, 
who writes, " This specimen resembles A. intermedia Spach but is not 
quite like our Ithaca plants. I have seen A. intermedia in New Eng- 
land only from the bog at Rutland, Vt." 
A. intermedia is a tall shrub, rarely a small tree, widely branching 
near the ground or at first growing in clumps : leaves elliptic-oblong or 
elliptic-obovate on the shoots; base rounded; apex acute; margin 
finely but somewhat distantly serrate ; veins irregular ; surface moder- 
ately tomentose when young, slightly so at maturity on the veins 
beneath and on the petiole ; young leaves often reddish ; racemes short 
(2 to 4 cm. long) 5- to 8- flowered, sparingly hairy; lower pedicels 8 to 
14 mm. long; sepals short (2 to 3 mm. long), hairy on the inner face; 
petals short (7 to 8 mm. long), oblong-cuneate ; fruit dark purple, 
juicy; fruiting racemes short, subcorymbose. The species grows in 
boggy soil, and should be looked for in bogs in Berkshire. Vid.
