16. CLARKIA PULCHELLA. 
A white variety of this pretty red species is offered 
by seedsmen. 1 Besides this a striped race sometimes oc- 
curs which has more or less numerous red bands of vary- 
ing breadth on the petals. 2 The red in these cases has 
the same intensity as that of the species. Moreover the 
white flowers are not pure white ; a very delicate but 
distinctly visible red flush can be seen on any bed of 
them in full flower. Sometimes 
occasional plants or individual 
flowers are somewhat richer in 
pigment, so that it is at once 
obvious that they are not pure 
white. 
I have only made an in- 
complete series of experiments 
with this plant because it does 
not lend itself easily to artificial 
fertilization and, as a rule, does 
not stand transplanting while 
in flower. But the results ob- 
tained suffice to demonstrate 
their essential correspondence 
with those obtained with Antirrhinum and Hes peris. 
We can distinguish in this as in the other two cases 
between a pale race poor in stripes and a richly striped 
one ; moreover these two races possess the characters of 
the corresponding ones in the two species named. But 
in Clarkia the broad stripes appear chiefly as sectors, as 
There is also a variety, Carnea, which is constant so far as my 
experience goes.
