organs of fecundation. A fruitful flower must have 
both pistils and stamens perfectly developed. The 
stamens are regarded as the male organs, and the pistils 
the female. When a flower has well-developed pistils, 
but no stamens, or imperfect ones, it must be impreg- 
nated by pollen from other flowers. Where a flower 
has no pistils, or has imperfect ones, it is utterly barren. 
A large number of our best American varieties—such 
as Hovey’s Seedling, Burr's New Pine, McAvoy’s Supe- 
rior, Moyamensing, &e.—are wanting In stamens, and 
therefore foreign impregnation is necessary. In Kurope 
this distinction is not observed to any extent, and all 
the English and continental varieties, as far as we know, 
are hermaphrodite. In this country very many of 
them fail from an imperfect development of the pistils, 
and are consequently barren, owing doubtless to the 
effects of climate and culture. It is not necessary 
that the two should be in close proximity; they are 
sure to get impregnated, if in the same garden, as the 
pollen is carried about from one flower to another by 
insects. The beds of the different sorts may be kept 
entirely separate. Mixing them up is a bad way, as 
the one outgrows and overruns the other, and they 
become so confused that nothing can be done with 
them. On this account many have grown tired of 
keeping up the distinction, and have resolved to culti- 
vate hermaphrodite sorts only. 
The following varieties are the best on the long list 
of those we have tested on our own grounds:

McAvoy’s Superior, Hovey’s Seedling, Moyamensing, 
Monroe Scarlet, and Crimson Cone. The finest fla-
