  • Malvaceae (incl. Bombacaceae, Sterculiaceae, Tiliaceae) We will focus mostly on the traditional "Malvaceae" (sub-family Malvoideae) but there are examples of "Bombaceae" (Kapok) and "Sterculiaceae" (Cacao) in the green house (big trees). "Tiliaceae" contains the Basswood tree, Fremontodendron is a distinctive local "Sterculiaceae". The description below is for the sub-family Malvoideae but mostly applies to Fremontodendron as well.

Androecium: Numerous monodelphous stamens (staminal tube) Gynoecium: 1 to many carpels (often 5), connate, ovary superior, capitate or lobed stigma Placentation: axile Fruit: Schitzocarp (splits into segments) or capsule Pollination regime: Bees, wasps, ants, flies,, moths, birds, bats - nectar reward. Interesting Species: Hibiscus, Marshmallow, Okra, Cotton [Cacao, Cola, Kapok, Gestalt: Monodelphous stamens, Palmate lobed leaves, Stellate pubsence on leaves Malvaceae
