heterostyled, a. Bot.|ˈhɛtərəʊstaɪld|
[f. hetero- + style + -ed2.]
Having the styles or pistils of different individual plants of different lengths relatively to their stamens; the same as heteromorphic or heterogonous.
1876Darwin in Life & Lett. (1892) 311 The nature of heterostyled plants may be illustrated in the primrose. 1877Amer. Jrnl. Sc. Ser. iii. 82 Mr. Darwin's term [dimorphism] has the disadvantage of not indicating what parts of the blossom are dimorphic..This has been supplied by Hildebrand, in Germany, who has introduced [Bot. Zeit. 1871] the term heterostyled and the counterpart homostyled.
So heteroˈstylism, ˈheterostyly, the condition of having the styles of different lengths relatively to the stamens; heteromorphism, heterogony; heteroˈstylous a. = heterostyled.
1875Bennett & Dyer Sachs' Bot. iii. vi. 809 Another contrivance for the mutual fertilisation of different individuals of plants with hermaphrodite flowers,—Dimorphism (or Heterostylism)..In one individual the flowers all have a long style and short filaments, while in another individual all the flowers have a short style and long filaments. 1876Darwin in Life & Lett. (1892) 53 This account was published before I had discovered the meaning of heterostylism. 1887Ward tr. Sachs' Phys. Plants 792 The same principle is also employed in the case of heterostylous flowers. 1887Goebel Morphol. Plants 405 A further method for securing the mutual fertilisation of different plants of the same species is heterogony (heterostyly). |
