Triffids: Carnivorous plants which possess a whip-like poisonous sting as well as mobility by three foot-like appendages, from the novel The Day of the Triffids (1951) by John Wyndham. They subsequently appeared in a radio series (BBC, 1960), a motion picture (1962), a TV series (BBC, 1981) and a sequel novel, The Night of the Triffids (2001 ...
Within Gynotrocheae, Crossostylis is morphologically distinct from other Gynotrocheae in having capsular fruits that split open at maturity and an appendage on a mature seed. [7] In addition, Crossostylis possesses a multi-celled archesporium in ovules just like members in Macarisieae, while the archesporium is one-celled in the other Gynotrocheae.

The other, in clusters in the axils of the leaves, produces seed. [ 5 ] Unlike many other members of the family Asteraceae , whose seeds are airborne with a plume of silky hairs resembling miniature parachutes , cocklebur seeds are produced in a hard, spiny, globose or oval double-chambered, single-seeded bur 8–20 mm (0.32–0.79 in) long.
Depending on the species, such awns have various seed-dispersal functions, either dispersing the seed by flinging it out (seed ejection); flinging away the entire carpel so that it snaps off (carpel projection); [2] entangling the awn or bristles on passing animals ; or possibly burying the seed by twisting as it lies on soft soil.

Typically, each body segment carries one pair of appendages. An appendage which is modified to assist in feeding is known as a maxilliped or gnathopod. [citation needed] In echinoderms an appendage called a pedicellaria is found. The end of the pedicellaria consists of valves that give a jaw-like appearance and is thought to be used to clear ...
