Wallace, Alfred Russel, 1823-1913

"Darwinism (1889)"

"De Candolle (_Mem. Soc. Phys. de Geneve_, tom. ii. part ii. p. 217)
states that Papaver bracteatum and P. orientale present indifferently
two sepals and four petals, or three sepals and six petals, which is
sufficiently rare with other species of the genus."
"In the Primulacae and in the great class to which this family belongs
the unilocular ovarium is free, but M. Dubury (_Mem. Soc. Phys. de
Geneve_, tom. ii. p. 406) has often found individuals in Cyclamen
hederaefolium, in which the base of the ovary was connected for a third
part of its length with the inferior part of the calyx."
"M. Aug. St. Hilaire (Sur la Gynobase, _Mem. des Mus. d'Hist. Nat._,
tom. x. p. 134), speaking of some bushes of the Gomphia oleaefolia,
which he at first thought formed a quite distinct species, says: 'Voila
donc dans un meme individu des loges et un style qui se rattachent
tantot a un axe vertical, et tantot a un gynobase; donc celui-ci n'est
qu'un axe veritable; mais cet axe est deprime au lieu d'etre vertical."
He adds (p. 151), 'Does not all this indicate that nature has tried, in
a manner, in the family of Rutaceae to produce from a single
multilocular ovary, one-styled and symmetrical, several unilocular
ovaries, each with its own style.
