Sex distribution in a neotropical willow,Salix martianaLeybold, has long escaped the attention of botanists. Its catkins are regularly composed of female, hermaphrodite and male flowers. The present paper discusses some aspects of its possible morphological and/or evolutionary significance. 

Fertility and sexual structure in a polygamous willow population

This note reports on an extraordinary polygamous population of Salix acmophylla from Nahal Dishon, Israel. Remarkably, all individuals in this population are bisexuals, that is, they all contain

Evolution of Catkins: Inflorescence Morphology of Selected Salicaceae in an Evolutionary and Developmental Context

The early developing inflorescences of Carrierea and Idesia show similarities to catkins which suggest possible pathways by which the salicoid catkin may have evolved.

Exceptions from dioecy and sex lability in genus Salix.

Bisexualism (and its derivatives) is a rare exception in species which already acquired the dioecious breeding system, except for willows, in which bisexualism occurs in at least 18 species.

Reporting Intersex Florets in Salix caprea L. (Salicaceae) from NE Anatolia

Male or female catkins composed of several intersexes florets in four individuals (all in the same population) of Salix caprea are reported from Turkey for the first time.

PIONEER TREES IN AMAZONIAN FLOODPLAINS: THREE KEY SPECIES FORM MONOSPECIFIC STANDS IN DIFFERENT HABITATS

Three pioneer tree species - Salix humboldtiana, Cecropia latiloba, Senna reticulata - form monospecific stands in the Central Amazonian white-water flood plain, and their preference for different habitats is reflected by different germination and early growth, by the structural and physiological characteristics, as well as by the reproductive and morphological adaptations.

Sex expression and inbreeding depression in progeny derived from an extraordinary hermaphrodite of Salix subfragilis

A genetic basis of extraordinary hermaphroditism and substantial inbreeding depression in survival and growth in the dieocious S. subfragilis is suggested.

SELF‐COMPATIBILITY AND ESTABLISHMENT AFTER ‘“LONG‐DISTANCE” DISPERSAL

The absence of Anoplura as primary infestants of South American land mammals seems to show that the sucking lice, as a group, originated at the earliest during the very late Mesozoic, if not at the beginning of the Tertiary.
