OBSERVATIONS ON THE FERTILISATION OF SAXIFRAGA. 75 
passing insect coming from a younger flower brushes by, and leaves a 
portion of the pollen behind it. 
The phenomena above described were noticed by me for the first 
time when gathering specimens of the White Meadow Saxifrage, with 
a view to verify and extend my observations of a former year on the 
variations in the parts of the flower as illustrative of vegetable 
morphology. 
Herewith I append a table of my notes of nine specimens of this 
flower, taken at random, which, I venture to believe, will be found to 
bear out my conclusions. Since making these notes I have had many 
opportunities of testing my first impressions in the examination of 
various individuals of the Saxifrapa umbrosa, S. granulata, and 
S. inuscoides, and the result has in every case verified my first impres¬ 
sions. With the hope that this simple record may encourage and 
stimulate all young botanists to a a closer observation of the common 
plants of our fields and woods, I herewith conclude. 
No. OF 
Floavek. Corolla. 
Stamens. 
Ovary.

Normal . 
Pollen shed. 
Stigmas across the apices of

inch apart. Stigmas im¬ 
mature ; vertically cleft ; 
and slightly leaning to each 
other.

Normal . 
Like No. 2. 
Styles more rudimentary than 
in No. 2, but touching.

Normal . 
Like No. 2, except¬ 
ing outer whorl of 
varying lengths, 
the longest dehisc¬ 
ing.

by insects. 
Pollen shed. 
Styles, one immature, the

rough as No. 1, and face to 
face. 
9.... 
Petals unusually 
long ; not shriv¬ 
elled.
