Loasaceae
Loasaceae is a family of 15–20 genera and about 200–260 species of flowering plants in the order Cornales, native to the Americas and Africa. Members of the family include annual, biennial and perennial herbaceous plants, and a few shrubs and small trees. Members of the subfamily Loasoideae are known to exhibit rapid thigmonastic stamen movement when pollinators are present. Taxonomy In the classification system of Dahlgren the Loasaceae were placed in the order Loasales in the superorder Loasiflorae (also called Loasanae). The Angiosperm Phylogeny Group system places them in the related order Cornales in the asterid clade. Genera 21 genera are accepted:Loasaceae Juss. '' |
Grausa
''Grausa'' is a genus of plants in the Loasaceae found in Chile and Argentina. It was previously included in the genus '' Loasa'' and was split to resolve a paraphyletic grouping of genera in the Loasaceae. The seeds of this genus have a characteristic hilar cone. Description ''Grausa'' is a small genus of perennial herbs. Species generally assume one of two vegetative habits, either rhizomatous with short internodes or climbing with winding aerial stems. The petiolate leaves are arranged in a basal rosette. Leaf shape ranges from sagittate to pinnatisect to ternately compound and rarely pinnate. The leaves are covered in rough trichomes with few or no stinging hairs. The inflorescences of ''Grausa'' species are axillary and may be one-flowered or branching and winding with multiple flowers. The bracts are pinnatisect or palmatisect. The flowers are borne on pedicels; those on one-flowered rhizomatous species are erect, whereas those on winding multi-flowered species are pendent ...

Cornales
The Cornales are an order of flowering plants, early diverging among the asterids, containing about 600 species. Plants within the Cornales usually have four-parted flowers, drupaceous fruits, and inferior to half-inferior gynoecia topped with disc-shaped nectaries. Taxonomy In the classification system of Dahlgren the Cornales were in the superorder Corniflorae (also called Cornanae). Under the APG IV system, the Cornales order includes these families: * Cornaceae (the dogwood family) * Curtisiaceae (cape lancewood) * Grubbiaceae (the sillyberry family) * Hydrangeaceae (the hydrangea family) * Hydrostachyaceae * Loasaceae (the stickleaf family) * Nyssaceae, (the tupelos) The oldest fossils assigned with confidence to the order are '' Hironoia fusiformis'', described from Coniacian age Japanese coalified fruits, and '' Suciacarpa starrii'' described from American permineralized fruits of Campanian age.

Thigmonasty
In biology, thigmonasty or seismonasty is the nastic movement, nastic (non-directional) response of a plant or fungus to touch or vibration. Conspicuous examples of thigmonasty include many species in the Fabaceae, leguminous family (biology), subfamily Mimosoideae, active carnivorous plants such as ''Dionaea (plant), Dionaea'' and a wide range of pollination mechanisms. Distinctive aspects Thigmonasty differs from thigmotropism in that nastic motion is independent of the direction of the stimulus. For example, tendrils from a climbing plant are thigmotropic because they twine around any support they touch, responding in whichever direction the stimulus came from. However, the shutting of a venus fly trap is thigmonastic; no matter what the direction of the stimulus, the trap simply shuts (and later possibly opens). The time scales of thigmonastic responses tend to be shorter than those of thigmotropic movements because many examples of thigmonasty depend on pre-accumulated turg ...
