bearer (A. hlepJiaropJiylld), very faint in the first, is entirely lost 
in the pure white of the second generation. 
In a word, in length of stem, habit of flowering, colour of 
flowers, and form of leaves, these plants of the second generation 
might, I venture to assert, be passed by any botanist as a new 
species, and fully verify what Darwin and you have enunciated as 
above noticed. 
If you think it worthy, would you kindly submit this commu- 
nication to the Scientific Committee, with the accompanying speci- 
mens, at their first meeting. 
I have, I find, given the particulars so fully of the first crop 
as to save the necessity of your referring to my letter of 
December 24, 1870. 
I shall be enabled some time during the summer, I expect, to 
communicate further results of crossing Begonias, having some 
of the lobes of the stigmas of the female flowers first removed. 
I communicated one instance of such a crop last year, where the 
seedling had wholly departed from the dioecious condition of the 
parents, and gone into the monoecious state. — I. Anderson-

May 12. — On looking over a bed of the same second generation 
of hybrid seedlings this morning, which I had planted apart from 
the others, I find many of them (forward to flower) of various 
habits and sizes, one of which, the smallest, I now enclose, No. 4. 
This tiny thing, not 2 inches in height, has, you will observe, 
6 flower-stalks, with large umbels (large for the plant) of flowers 
at the top, and some having flowers at the axils. All the brood 
strongly illustrate your doctrine of variation, as not one of them 
ofiers a return to either parent, and the excessive tendency to 
flower is most noteworthy in them all.
