and would, in a case like A. spicata (Lamarck) Koch, restrict a 

 new binomial to a plant to which an older specific name has been 

 mistakenly transferred, A. sangidnea would have precedence over 

 all others. 



The second form has been known as A. oralis and A. spicata, 

 the former an unavailable name, and is abundant in many parts of 

 New England and probably extends much farther west. It may 

 be described as 



Amelanchier erecta sp. nov. A slender erect shrub, 4 to 12 

 feet high, sparingly branched, growing in colonies and making a 

 thick hedge. Twigs very erect, stocky. Buds very woolly when 

 breaking, bud-scales short ; bracts dark-purple, the starting leaves 

 often yellow. Leaves very woolly on the under side when young, 

 glabrous when fully grown, broad- oval, rounded or slightly 

 cordate at the base, point short and broad or wanting, rather 

 coarsely serrate-dentate or often even finely serrate ; the leaves 

 on vigorous new wood larger, often very broad, sometimes nearly 

 orbicular. Flowers not large, often having a spread of less than 

 an inch, often light-yellow, in close, stocky racemes, densely 

 woolly. Fruit on erect pedicels in close erect clusters, the calyx- 

 lobes rather short, reflexed-curled, rather small, the top of the 

 pome densely woolly within the calyx lobes. Starts some days 

 later than A. canadensis and ripens its fruit several weeks later. 



Type in herbarium of W. H. Blanchard. 



The fruit seems to drop badly when nearly ripe, and with the 

 depredations of birds ripe fruit is often scarce. Abundant and 

 typical in and around Bellows Falls, Vt., both on rocks and in 

 dry or loamy soil. 



The evidence seems to be pretty conclusive that Lamarck's 

 spicata is the northern form of Michaux — his rotnndifolia- 

 Lamarck's description agrees well with Michaux's. He says 

 that the plant he described grew in the Royal Garden and in 

 private grounds and was supposed to be a native of Canada. The 

 close connection of Canada to France until 1763 makes it almost 

 certain that Canada was its home. There is no reason to suppose 

 it came from a more southern region. Koehne evidently tried to 

 include in his spicata both the northern and more southern forms, 

 but his description and his specimens apply to the more southern 

 form.
