 Illustration:— Fig. 23.   
 Common names and documented uses:— Colombia: “morita” (Galeano et al. 3622, COL-internet image!); Nicaragua: “jaboncillo” (Ortiz 75, CAS!, MO!).   
 Habitat, distribution and ecology:— Local, on river banks, understories and disturbed sites in lowland rain forests and premontane wet forests, usually found in deep shade, from Nicaragua through southern Central America to Colombia (Fig. 16), at 0–1500 m. In Nicaragua it is found in the Atlantic and North-central zones (Almeda 2001), in Costa Rica it is present throughout the country, and it has been collected in Panama (Bocas del Toro and Darién) south to Colombia, where it is only known from the San José del Palmar region (Chocó and Risaralda), and was recently collected in the Eastern Cordillera of the Andes.   
 Phenology:— Collected in flower and fruit throughout the year.   
 Etymology:— From a family name (Reitz). Gleason did not specify derivation of this epithet in the protologue.   
 Discussion:— This species is distinguished by the dense pink-setose pubescence on internodes, inflorescence rachis, foliar surfaces and hypanthium. Miconia quinquenervia shares similar setose exterior calyx teeth and glandedged staminal connective appendage. Miconia neocoronata also has an adaxially ciliate torus like M. reitziana and resinous-glandular hypanthium, but lacks elongate trichomes on the foliar surfaces and hypanthium. Phylogenetically, M. reitziana is sister to both M. aguilarii and M. quinquenervia (Fig. 1), both of which differ from the former in having foliar bases decurrent on the petioles.   
Occasionally but not consistently, in all the material studied, the resinous-glandular vestiture is also present on the upper internodes, veins and venules abaxially, but obscured by the more conspicuous asperous indumentum as noted by Almeda (2009). The anisophylly in this species is not present in every pair of leaves of an individual. Some leaf pairs are isophyllous, but every individual has several pair of anisophyllous leaves.  
 There is a recent collection from the department of Boyacá (Alvear et al. 1440, CAS!, COL) that certainly belongs to the M. reitziana alliance. The vegetative and floral dimensions are congruent, as well as floral characters, and the adaxial torus is ciliate although sparsely so. The hypanthium vestiture consists of rusty asperous trichomes and resinous-glandular trichomes, but with a few smooth pinkish trichomes. Phylogenetically this taxon branches before M. reitziana, but both belong to the same clade. In this part of the tree (Fig. 1) there is not enough statistical support to separate M. reitziana from this Boyacá population; therefore the exact relationship between these two entities remains to be resolved. The Alvear collection is from the western slope of the Eastern Cordillera of the Andes, a region from which no previous collections of M. reitziana are known. Considering the distance between the known populations of M. reitziana in Colombia, this specimen would represent the easternmost occurrence of this taxon; therefore, the slight morphological differences may be associated with its geographic isolation. More collections are needed for a better understanding of the distribution of this species in the Colombian Andes.   
 Conservation status:— This species would be considered Endangered EN B2ab(iii) according to IUCN criteria (AOO). Because it occurs in many protected areas, a status of Least Concern LC is warranted. Protected in Colombia in the Aves El Paujil Natural Reserve (Boyacá). In Costa Rica it is protected throughout the country in several National Parks and Reserves. In Nicaragua it is protected in the Bosaws Reserve (Jinotega). In Panama it is protected in the Darién National Park (Darién).
