1. BRUNNICHIA Banks 
With the exception of Muehlenbeckia, which is found in tropical 
America and in Australia, New Zealand, and the islands of the 
Pacific, Brunnichia is the only genus of the tribe Coccolobeae not 
confined to America. The type species, B. cirrhosa Gaertn., 
occurs in eastern North America, the three other known species 
coming from the region of the Belgian Congo and Camerun in 
western Africa. The genus may be divided into two sections, 
separated by habitat and by definite fruiting characters. In the 
section Eubrunnichia, sect. nov., including only the type species, 
B. cirrhosa, the tube of the perianth and the pedicel bear a single 
broad wing, and the perianth tube is much thickened and corky 
in fruit. In the African group, which may be called section 
Dipteropodium, sect. nov., the tube of the perianth and the 
pedicel bear two broad wings, and the perianth tube in fruit is 
coriaceous and not obviously thickened. This section includes 
three species, B. africana Welw. (type), B. erecta Aschers., and 
B. congoensis Dammer.* Of this group I have examined only a 
sheet of B. africana var. glabra Dammer, in the U. S. National 
Herbarium. 
Brunnichia erecta Aschers. was originally described as an erect
