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 and from Sagada, both in the Philippines, have slightly different hunting tactics, and Los Baños has some very dangerous prey spiders. In laboratory tests, Los Baños "P. labiata"s rely more on trial and error than Sagada "P. labiata"s in finding ways to vibrate the prey's web and thus lure or distract the prey. Around Los Baños the web-building "Scytodes pallida", which preys on jumping spiders, is very abundant. All members of the genus "Scytodes" spit a sticky gum on prey and potential threats, and this can immobilise a "Portia" long enough for the "Scytodes" to wrap the "Portia" in silk
