Flowering plant magnoliid (2%) clades. The remaining 5 clades contain a little over 250 species in total; i.e. less than 0.1% of flowering plant diversity, divided among 9 families. The 43 most-diverse of 443 families of flowering plants by species, in their APG circumscriptions, are Of these, the Orchidaceae, Poaceae, Cyperaceae, Araceae, Bromeliaceae, Arecaceae, and Iridaceae are monocot families; Piperaceae, Lauraceae, and Annonaceae are magnoliid dicots; the rest of the families are eudicots. Double fertilization refers to a process in which two sperm cells fertilize cells in the ovule. This process begins when a pollen grain adheres to the stigma of the
Portia labiata occasionally jump on an insect. However, "Portia"s are not very good at catching moving insects and often ignore them, while some other salticid genera, especially the quick, agile "Brettus" and "Cyrba", perform well against small insects. When a "Portia" stalks another jumping spider, the prey generally faces the "Portia" and then either runs away or displays as it does to another member of its own species. The webs of spiders on which "Portia"s prey sometimes contain dead insects and other arthropods which are uneaten or partly eaten. "P. labiata" and some other "Portia"s such as "P. fimbriata" (in Queensland) and
