RANUNCULUS FASCICULARIS Muhl.—This is the common 
early buttercup, blooming from March 24thto May 19th. The 
stems rise about 1. Each plant commonly shows only one 
or two open flowers at a time, so that in this case pollination 
between distinct plants is apt to occur; but well developed 
plants often show several flowers, when pollination is more 
likely to take place between flowers of the same plant. 
The flowers are bright yellow, expanding from 15 to 25™™. 
Newly opened flowers are less widely spread. They show 
the indehiscent anthers crowded in a compact mass, and the 
stigmas surpassing them by 1-2™". At this time, the stigmas 
are receptive, and I have often found them thoroughly dusted 
with pollen which must have come from other flowers. The 
flowers are therefore proterogynous and are generally cross- 
pollinated. In older flowers the petals are lengthened and 
“teal expanded. The stamens also lengthen and finally over- 
top the stigmas, the anthers nearly concealing them. At this 
time, if fertilization has not already taken place, spontaneous 
self-pollination may readily occur by the stigmas receiving 
Pollen from the anthers which now overtop them, and often 
touch them, as in the preceding.
