SYNOPSIS OF SECTIONS 
SUBGENUS Lopho stigma, subgen. nov. 
Carpellae drupas distinctas formant. Carpels 
distinct, in fruit forming drupes. 
HOLOTYPUS: section Lopho stigma (Brongn.) 
Warb., in Engler’s Pflanzenreich IV, fam. 9: 71, 
1900. 
There has been effectively published the sub- 
generic name Aero stigma by Martelli, Soc. Tosc. 
Sci. Nat., Atti, Proc. Verb. 42: 56, 1933. How- 
ever, this name was printed without a description 
or a reference to one. This taxon "sottogenere” 
was not formally accepted by its author, Martelli, 
and he used it indiscriminately with "sezione,” 
but the latter taxon, the section, was the one he 
actually accepted. 
The sections in this subgenus follow in alpha- 
betical order:
