Description edit
Plants in the genus Sphaerolobium are perennial shrubs, the stems often rush-like, leafless and winged or ridged. The leaves, when present are simple, linear and lack stipules. The sepals are joined forming a bell-shaped tube with five overlapping teeth, the upper two forming a curved "lip". The petals are yellow or red and pea-like, the keel shorter than the other petals. The fruit is a spherical or flattened pod containing one or two seeds.[2][3][4]
Taxonomy edit
The genus Sphaerolobium was first formally described in 1805 by James Edward Smith in Annals of Botany.[5][6] The name Sphaerolobium means "ball-pod".[7]
