[ Back to top ]

Trees, shrubs, or woody climbers, rarely herbs; hairs sclerified and/or silicified, sometimes fasciculate. Leaves simple, rarely pinnatisect or pinnately compound, usually spirally arranged, rarely opposite, petiolate; stipules absent; petiole sometimes winged; leaf blade leathery, herbaceous, or membranous, margin entire or serrate. Flowers bisexual, rarely unisexual, actinomorphic, occasionally zygomorphic, solitary or in racemes, panicles or cymes. Sepals (3 or) 4-5(-18), imbricate, persistent, usually leathery or fleshy, sometimes accrescent in fruit. Petals (2 or) 3-5(-7), white, yellow, or red, imbricate, crumpled in bud. Stamens numerous (or 1-10), developing centrifugally, free or united basally and then in fascicles; staminodes often present; anthers basifixed, dehiscing by longitudinal slits, apical clefts, or apical pores. Gynoecium (1 or) 2-7(-20) -carpellate, superior; carpels free or hemisyncarpous; stylodia free, apically stigmatic; ovules 1 to numerous, anatropous; placentation submarginal, or basal when ovules 1 or 2. Fruit a follicle, polyfollicle, berry, or capsule, or indehiscent and enclosed by fleshy sepals. Seeds 1 to numerous; endosperm copious, oily; embryo very small, straight, achlorophyllous.

Candollea

Stylidium (also known as triggerplants or trigger plants) is a genus of dicotyledonous plants that belong to the family Stylidiaceae. The genus name Stylidium is derived from the Greek st???? or stylos (column or pillar), which refers to the distinctive reproductive structure that its flowers possess. Pollination is achieved through the use of the sensitive "trigger", which comprises the male and female reproductive organs fused into a floral column that snaps forward quickly in response to touch, harmlessly covering the insect in pollen. Most of the approximately 300 species are only found in Australia, making it the fifth largest genus in that country. Triggerplants are considered to be protocarnivorous or carnivorous because the glandular trichomes that cover the scape and flower can trap, kill, and digest small insects with protease enzymes produced by the plant.
