Some plants were described by me several years ago, in a series of papers read before the Linnean Society the individuals of which exist under two or three forms, differing in the length of their pistils and stamens and in other respects. They were called by me dimorphic and trimorphic, but have since been better named by Hildebrand, heterostyled.

In March 1867, Darwin received a small book from Hildebrand on plant sexuality. Hildebrand suggested a more accurate term with which to refer to the sexual system of dimorphic and trimorphic plants: heterostyly (Hildebrand 1867a, p. 46).

Narcissus, the daffodil genus, exhibits an unusual diversity of sexual systems, with populations that are monomorphic, dimorphic or trimorphic for style length. Associated with this variation are striking differences among …

Dimorphic: It is simplest and commonest pattern of polymorphism ; They have only two types of zooids (gastrozooids and gonozooids) and the phenomenon is known as dimorphism. Exhibits by many Hydrozoan colonies; …

Morphological characteristics of dimorphic and trimorphic populations. We used general linear models (GLM procedure, SAS) to determine if there was a difference between dimorphic and trimorphic populations in floral and vegetative traits.

When a colony has two zooids, it is dimorphic; when it has three, it is trimorphic; and when it has numerous, it is polymorphic. 1. Dimorphic. This is the simplest and most prevalent …

Monomorphic pertains to a single form or shape, while polymorphic describes entities with multiple forms or shapes. Monomorphic refers to entities or systems that exhibit or assume only one form, shape, or manifestation.

I n the previous chapters various heterostyled dimorphic plants have been described, and now we come to heterostyled trimorphic plants, or those which present three forms. These have been observed in three families, and consist of species of Lythrum and of the allied genus Nesæa, of Oxalis and Pontederia.

It is possible to raise from dimorphic species, both long-styled and short-styled illegitimate plants, and from trimorphic plants all three illegitimate forms. These can then be properly united in a legitimate manner.

When a colony has two zooids, it is dimorphic; when it has three, it is trimorphic; and when it has numerous, it is polymorphic. 1. Dimorphic. This is the simplest and most prevalent polymorphism pattern displayed by the majority of hydrozoan colonies. They have only two varieties of zooids, hence their dimorphic designation.
