Floral characteristics of species with the Lapeirousia silenoides-type flower. The floral
tube is closed in the lower 10-12 mm in B. curviscapa, 20-30 mm in B. dregei, and 15-20 mm in
B. framesii, hence floral tube length does not reflect the distance that an insect must extend its
mouthparts to reach the nectar.
Z= zygomorphic; A= actinomorphic.
