Rubiacearum Americanarum Magna Hama Pars XV. New Species and Two New Combinations in Notopleura (Psychotrieae) from Central and South America

Abstract

Notopleura (Bentham & Hooker f.) Bremekamp is a Neotropical genus of about 100 species that was formerly included in Psychotria, but differs from that in its low succulent habit, stipules with a single usually glandular interpetiolar appendage, and terminal or often pseudoaxillary inflorescences. Notopleura is widely distributed in wet habitats and includes two subgenera: subgenus Notopleura, which comprises terrestrial, usually unbranched plants and includes most of the species in the genus, and subgenus ViscogogaS which comprises epiphytic, usually branched plants. In subgenus Notopleura here the new combination N. madida (Standley) C. M. Taylor is made based on Psychotria madida Standley of Ecuador, and 21 new species are described and illustrated: N. amicitiae C. M. Taylor of eastern Costa Rica and western Panama, which has been confused with N. aggregata (Standley) C. M. Taylor; N. biloba C. M. Taylor of northwestern Colombia, which has been confused with N. macropodantha (Standley) C. M. Taylor; N. bryophila C. M. Taylor of montane Ecuador, which has been confused with N. marginata (Bentham) Bullock; N. capitata C. M. Taylor, found from Nicaragua to Panama and previously confused with N. aggregata; N. corniculata C. M. Taylor of western Colombia and Ecuador, which has been confused with N. anomothyrsa (K. Schumann & Donnell Smith) C. M. Taylor; N. corymbosa C. M. Taylor of Ecuador, which has been confused with N. micayensis (Standley) Bremekamp; N. costaricensis C. M. Taylor of montane Costa Rica, which has been confused with N. aggregata; N. hurtadoi C. M. Taylor of Ecuador, which has been confused with N. Ieucantha (K. Krause) C. M. Taylor; N. hypolaevis C. M. Taylor of Ecuador, which has been confused with N. uliginosa (Swartz) Bremekamp; N. Iongiflora C. M. Taylor of northwestern Colombia, which has been confused with N. macropodantha; N. montana C. M. Taylor of montane Costa Rica to Venezuela and Peru, which has been confused with N. macrophylla (Ruiz & Pavon) C. M. Taylor; N. NOVON 13: 228-260. 2003. multinervia C. M. Taylor of montane western Panama, which has been confused with N. aggregata; N. obtusa C. M. Taylor of Ecuador and northern Peru, which has been confused with N. aequatoriana C. M. Taylor; N. pacorana C. M. Taylor of central Panama, which has been confused with N. panamensis (Dwyer) C. M. Taylor; N. parvifolia C. M. Taylor of western Panama, which has been confused with N. aggregata; N. pendulifora C. M. Taylor of western Panama, which has been confused with N. plagiantha (Standley) C. M. Taylor; N. sanblasensis C. M. Taylor of central Panama, which has also been confused with N. panamensis; N. spiciformis C. M. Taylor of western Colombia and Ecuador, which has been confused with N. Iongipedunculoides (C. M. Taylor) C. M. Taylor; N. torrana C. M. Taylor of western Panama, which has been confused with N. macropodantha; N. tubulistipula C. M. Taylor of Ecuador, which has again been confused with N. aggregata; and N. zarucchiana C. M. Taylor of montane Colombia, which has also been confused with N. macropodantha. Also in subgenus Notopleura, the correct names and their authorship are discussed for the species N. Iongipedunculoides (the formal new combination made here), N. Iongissima Bremekamp, and N. micayensis. In subgenus Viscagoga five new species are described and illustrated: N. bahiensis C. M. Taylor, which is similar to N. multiramosa (Steyermark) C. M. Taylor; N. cocleensis C. M. Taylor from western Panama, which has been confused with N. guadalupensis (DC.) C. M. Taylor; N. elegans C. M. Taylor from Costa Rica and western Panama, which has also been confused with N. guadalupensis; N. episcandens C. M. Taylor & Lorence from eastern Panama, which has been confused with N. maxonii (Standley) C. M. Taylor; and N. vargasiana C. M. Taylor from Ecuador, which again has been confused with N. guadalupensis.
