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 spiders, none of which are as dangerous to "P. labiata". The Los Baños variant has a slightly wider repertoire of tactics. In the Philippines, "P. labiata" does not prey on ants, but is preyed on by the ants "Oecophylla smaragdina" and "Odontomachus" sp. (species uncertain), and a solitary "Odontomachus" has been seen attacking a "P. labiata". In a test the ant "Diacamma vagans" usually killed single-handed a "P. labiata". "P. labiata" is one of 17 species in the genus "Portia" as of May 2011. This species has been named "Sinis fimbriatus" (Hasselt, 1882; misidentification), "Linus labiatus" (Thorell, 1887), "Linus dentipalpis"
