minima from Grand Savanne (Wilbur 8351).
This taxon was named Teramnus labialis subsp. arabicus
Verdcourt (1970272), the subspecies (Africa and Neotropics)
being defined by granulate rather than shining seeds.

marina (Burman) Memll may be the correct name for this
species. Alston (1931) separated V. marina from V. luteola.

Flacourtia cataphracta Roxburgh ex Willdenow), is a dioecious
shrub with thorny stems and a berry-like fruit. It was
