Are Bidens and Browningia both types of barbed plants?
Bidens Bidens is a genus of flowering plants in the aster family, Asteraceae. The common names beggarticks, black jack, burr marigolds, cobbler's pegs, Spanish needles, stickseeds, tickseeds and tickseed sunflowers refer to the fruits of the plants, most of which are bristly and barbed, with two sharp pappi at the end. The generic name refers to the same character; "Bidens" comes from the Latin "bis" ("two") and "dens" ("tooth").
Brugmansia Brugmansia is a genus of seven species of flowering plants in the family Solanaceae. They are woody trees or shrubs, with pendulous flowers, and have no spines on their fruit. Their large, fragrant flowers give them their common name of angel's trumpets, a name sometimes used for the closely related genus "Datura". (Datura differs from Brugmansia in that they are herbaceous bushes, with erect rather than pendulous flowers - and most have spines on their fruit).
