MEMOIRS OF THE NEW YORK BOTANICAL GARDEN. 229 



* Amelanchier pumila Nutt. ; Torr. & Gray, Fl. N. Am. i: 474, 



as synonym ; Amelanchier Canadensis s punii/a Torr. & Gray 1. c. 



A low bush, 1-2 meters high, with rounded thick leaves, which 

 are sharply serrate all around and glabrous. Grows on dry hillsides, 

 at an altitude of about 2000 m. 



Montana: Bridger Mts., June 18, 1897, Rydberg & Bessey^

* Amelanchier florida Lindle}-, Bot. Reg. /. ijSg; Amelanchie?- ovalis 



(i senii-i)itegyifolia Hook. Fl. Bor. Am. i : 202. 



It is probable that Hooker's name is slightly older. His Flora was 

 issued in parts; the first volume was issued between 1830 and 1833, 

 but the exact date I cannot ascertain. The plate 1589 of the Botan- 

 ical Register was published in June, 1833. Amelanckie?- Jiorida 

 resembles A. alnifolia in size, but the leaves are narrower, oblong 

 or oval, serrate only at the apex and white woolly when young. It 

 grows at an altitude of 1000-2500 m.

* Amelanchier Utahense Koehne, Berlin Oestern. 32 : 2. 



Like A. alnifolia, but with smaller thicker and tomentose leaves.
