OF NORTH AMERICA*

Puberulent or pulverulent, branches angular 
purplish, leaves petiolate glaucous cuneate en* 
tire or apex crenate dentate obtuse, base acute, 
smooth above, trinerve and puberulent beneath, 
corymbs terminal on branchlets pauciflore sub- 
umbellate, stamens very short — Europe from 
Spain to Hungary ; my specimen is from Hun- 
gary, with branches ramose not vir gate, leaves 
small semiuncial, flowers white, corymbs 5-7 
flore, pedicels puberulent sometimes with a su- 
bulate bract. This Linnean sp. is not Ameri- 
can, Hooker has it not, Smith has proved that 
several sp. were blended, the Sibirian is my 
next. Even Linneus in taking barrelier’s plant 
as type, mistook others for it and called the 
leaves ovatoblong, he meant obovate oblong* 
The name being equivocal and liable to objec- 
tions, might be changed to Sp .. pulverulenta 
Raf. 
663. Spirea (Oh.) benticulata Raf. ere- 
nata Pallas, fl. 1. 19. Wild. Pers. &c. Smooth, 
branches yellowish, leaves sessile obovate or 
cuneate denticulate acute upwards, beneath 
glaucous, lower leaves petiolate ovate denticu- 
late, corymbs lateral pauciflore — Sibiria and 
probably New Sibiria, flowers white ; even Pal- 
las speaks of some varieties, one with laciniate 
trinerve leaves may be a distinct Sp. laciniatal 
Raf. 
664. Spirea (Ch.) japonica Raf. crenata 
Thunb. fl. Smooth, branches virgate, leaves pe- 
tiolate lanceol, hardly serrate, flowers umbel- 
late, calix campan. deeply 5'fid. petals emargi- 
nate — in Japan, called there Awaju, another 
mistaken reference to Sp. crenata, quite dis- 
tinct from all, nearer to the next by the um- 
bels.
