(on 60. flowers.) many plants, "intermediate" (means between parent) "nec omnino steriles" for the hybrid capsules 'sponte' often gave one or two good seeds. These hybrids gave many progeny ((p.341) "a priori ipsarum statu hybrido plus minusve aberrantes." They far exceeded in size &c luxuria caulium even L. perenne. — vegetated during many years & much multiplied by cuttings.

Inverse tried (viz L. aust ♀ with L. perenne) on 55 flowes same year all failed!! & yet we have seen hybrids produced of themselves seeds !!

What beautiful gradation in degrees of fecundity in this one genus. —

Tried 20 experiments & all failed between species of this genus (between two British species) always tried in inverse ways & generally on many flowers.

N.B zz

In this paper on Dianthus fertility of Hybrids seldom mentioned, except in last experiment. — I conclude not always fertile. but we shall afterwards see that he brought back all the hybs. by crossing with one parent, to metamorphous —

See Pamphet if there be any failures — it is most remarkable if he succeeded in crossing all pinks & so many giving plenty of seeds & yong plants whilst he fails so often in mny speces other genera. —
