dicotylous

One might easily imagine that by this means the dicotylous seedlings could be rendered pure.

As may be expected, individual differences occur, and it must even be supposed that some of the original tricotyls may not be pure, but hybrids between tricotylous and dicotylous parents.

The parent itself may be tricotylous or dicotylous, or show any amount of multiplication and cleavage in its seed-leaves, but it always gives the entire range among its progeny of the variation.

With the _Phacelia_ and the mercury and some others I had the good luck in this one generation to reach as high as nearly 90\% of tricotylous seedlings, a figure indicating that the normal dicotylous type had already become rare in the race.

Some tricotyls will be found among every thousand seedlings in many species, while in others ten or a hundred times, as many plants must be examined to secure them, but species with absolutely pure dicotylous seeds are very rare.
