Abstract
Capparis is represented in Cuba by six species of four
sections. A key for their identification is provided, their
nomenclature and that of the sections in which they belong is
revised, and the intricate relevant typification problems are
discussed. Three species, each of a different section, are not
critical taxonomically. The other three, which belong to C.
sect. Breyniastrum, have been poorly understood and often
confused in the past. Microcharacters of trichome and leaf surface
morphology (illustrated by SEM photographs) prove useful to tell
them apart. In conclusion, two Macroantillean species are
recognised, each represented in Cuba by a distinct, endemic
subspecies (one new, one recombined); a third species, C.
singularis, known from a single E Cuban gathering, is described
as new to science. Distribution maps are provided of these three
Cuban endemics, and the relevant specimen data are included, as a
searchable database, in an electronic supplement to the present
paper.
