HEUCHERA HISPIDA Ph.—Each plant of this common 
species bears several scapes, which rise 6 to 9 dm., ale 
long panicles of greenish flowers. lower 
e calyx is oblique, being quite gibbous on the low 
side. It measures about 6 mm. in length, the lobes — 
directed forward and a little inward and the petals filling on 
intervals, so that the effect is much the same as if the ae 
were united to their tips. The tube is very broad, poe a 
about 4 mm. wide, so that it readily admits the hea 
thorax of a bee. : 
The stamens lengthen and discharge pollen in s 
beginning with the upper one. Accordingly, yas 
the pollen, the flower must be visited several times. a 
The flowers are proterogynous * with long-lived pecan 
and are remarkable for being visited exclusively by 4 SP
