Pollination systems in the Asclepiadaceae: a survey and preliminary analysis☆
Using published and unpublished records of pollination in the dicot family Asclepiadaceae (the ‘milkweeds’) we offer a preliminary analysis of present-day pollination systems in the family. VariationExpand

Floral biology and pollination in stapeliads — new results and a literature review
The myiophilous pollination syndrome of stapeliads is investigated. Olfactory stimuli, imitating dung or decaying organic (zoogenic or phytogenic) matter, are used as attractants, together withExpand

Some observations on pollination in Mexican asclepiadaceae
Flower-insect interaction was studied in three Mexican asclepiad species, a member of the Matelea reticulata complex, Cynanchum foetidum and Funastrum arenarium. In the Matelea reticulata population,Expand
