Trimorphic incompatibility in Eichhornia azurea (Pontederiaceae)

Sexual Plant Reproduction, 2000
Eichhornia azurea (Pontederiaceae) is a mat- forming, clonal aquatic that inhabits lakes, marshes and river systems in many parts of the Neotropics. The spe- cies is tristylous with long-, mid-, and short-styled morphs commonly represented in natural populations. To investigate whether E.

Developmental heterophylly in the genus Heteranthera (Pontederiaceae)

Aquatic Botany, 1988
Abstract Plants of 8 species were grown from seed in 2 water depths to investigate heterophylly within the genus Heteranthera . All species developed submersed sessile leaves. Subsequent development varied among species in: (1) the number of sessile leaves; (2) petiole length, blade length, blade width and length to width ratio of petiolate leaves; (

THE DEVELOPMENTAL BASIS OF TRISTYLY IN EICHHORNIA PANICULATA (PONTEDERIACEAE)

American Journal of Botany, 1984
Eichhornia paniculata is a tristylous, self‐compatible, emergent aquatic. A given plant produces flowers with either long, mid or short styles and two levels of stamens equal in length to the styles not found in that flower.

Variation in expression of trimorphic incompatibility in Pontederia cordata L. (Pontederiaceae)

Theoretical and Applied Genetics, 1985
Pontederia cordata L. (Pontederiaceae), a perennial diploid, possesses the rare genetic polymorphism tristyly. A controlled pollination programme was conducted over a three year period, under glasshouse conditions, on 36 clones of P. cordata var. cordata to examine the nature of the self-incompatibility system.
