Lectotypus (designated here): MOZAMBIQUE: Shigogo , XII.1860, Kirk s.n. ( K [ K000412356 , plant on upper left] image seen) . Syntypus: MOZAMBIQUE: Shiramba , XII.1860, Kirk s.n. ( K [ K000412356 plant on lower right] image seen) .

Notes. – This species is found in Democratic Republic of Congo, Kenya, Tanzania, Mozambique, Malawi, Zambia, Zimbabwe, and Angola ( VERDCOURT, 1977). This species was illustrated by VERDCOURT (1976: 118, fig. 8, 1989: 36, fig. 5), as Chazaliella abrupta var. abrupta . The name Psychotria abrupta apparently has not been lectotypified previously. This name was described based on two syntypes, both collected by Kirk in Mozambique and both mounted on one sheet at K [K000412356]. The plant on the upper left of that sheet has flowers and also shows well the characteristic indurated stipules, stem internodes with a medial longitudinal ridge, and whitened corky bark that is characteristic of Eumachia , and this plant is designated here as the lectotype. The other syntype has two inflorescences from which the corollas have fallen and stipules that have mostly already broken off.
