Introduced originally by David Douglas from Western 
North America about 1826, Amelanchier florida has pro- 
bably been in cultivation during most of the period that 
has elapsed since then, although latterly it has been con- 
founded with A. alnifolia, Nutt., both in gardens and in 
botanical works. Growing together, as these two species 
are at Kew, they are seen to be quite distinct. A. alni- 
_folia is a small tree; A. florida is a caespitose shrub, its 
slender erect stems forming quite a thicket. The leaves 
of A. florida are toothed farther down the margin; the 
hypanthium is much less woolly or even quite glabrous 
on the outside; and it flowers in early May about a 
fortnight in advance of A. alnifolia.. The plant from 
which our plate was prepared was obtained from a 
continental nursery in 1906 as A. oxyodon, but a com- 
May, 1915.
