Besides tricotylous, the syncotylous seedlings may be used in the same way. They are more rarely met with, and in most instances seem to belong only to the unpromising half-races. On the other hand I found a plant of Centranthus macrosiphon yielding as much as 55% of syncotylous children and thereby evidently betraying the nature of a rich or double race.
