Actinocephalus polyanthus (Actinocephalus polyanthus)
Description
The species are mostly herbaceous perennial plants 0.3�1.5 m (0.98�4.92 ft) tall, but some are annual plants and a few are shrubs up to 3 m (9.8 ft) tall. An exception is the chamis de monte (Lupinus jaimehintoniana) of Oaxaca in Mexico, which is a tree up to 8 m (26 ft) tall.4 Lupins have soft green to grey-green leaves which may be coated in silvery hairs, often densely so. The leaf blades are usually palmately divided into five to 28 leaflets, or reduced to a single leaflet in a few species of the southeastern United States. The flowers are produced in dense or open whorls on an erect spike, each flower 1�2 cm long. The pea-like flowers have an upper standard, or banner, two lateral wings, and two lower petals fused into a keel. The flower shape has inspired common names such as bluebonnets and quaker bonnets. The fruit is a pod containing several seeds that weight in average 24,8 mg each (n=50).
