Studies in the Capparaceae XXVI. Capparis bonifaziana, a new species and western Ecuadorian sister to the mostly Amazonian C. macrophylla

Abstract:

From subgenus Capparidastrum s.l. (Capparaceae), Capparis bonifaziana, a small to medium-sized tree endemic to the western, Pacific slope of Ecuador, is newly described as an allopatric segregate of the much more widespread but rare C. macrophylla s. str., of the mountains and valleys of the northern Andes to the tropical lowlands of western and southwestern Amazonia. The new species differs by its more conspicuous and larger episepalous glands, smaller anthers, ovaries, and erect petals; smaller number of stamens; elliptic to oblong, rather than broadly ovate leaves; and longer and narrower baccate fruits. Both taxa are described, compared, illustrated, mapped, and with all their known specimens listed.
