The Different Forms of Flowers on Plants of the Same Species

Illegitimate offspring from all three forms of Lythrum salicaria. Their dwarfed stature and sterility, some utterly barren, some fertile. Oxalis, transmission of form to the leg...

Linum grandiflorum, long-styled form utterly sterile with own-form pollen. Linum perenne, torsion of the pistils in the long-styled form alone. Homostyled species of Linum. Pulm...

cross perfectly resembling, in a considerable number of important characters, the father alone. It is, therefore, very improbable that a pure cowslip crossed by a primrose shoul...

smaller and less conspicuous flowers are not closed, but as far as the purpose which they serve is concerned, namely, the assured propagation of the species, they approach in na...

both species are heterostyled, their complete fertilisation depends on insects. The cowslip is habitually visited during the day by the larger humble-bees (namely Bombus muscoru...
