Terminalia uleana Engl. ex Alwan & Stace Ann. Missouri Bot. Gard. 76(4): 1127. 1989 Engler wrote the name "Uleana" on the sheet
at B but did not publish it. Also written on the
sheet is the idea that the species is related to T.
argentea. The new species belongs to sect. Aus-
trales Engl. & Diels, itself close to sect. Diptera,
which contains T. argentea. Of the species in sect.
Australes, T. uleana differs from T. australis Cam-
bess. and T. reitzii Exell in fruit shape and from
T. trifora (Griseb.) Lillo by having wider leaves
and wider fruits with a differently shaped wing.
The fruit wing of T. uleana is often curved down-
ward (retrorsely), and this character is diagnostic;
a third rudimentary wing is often present. The
species has not been found since 1889.
