Synopsis of Randia (Rubiaceae) of Bolivia
Background and aims: Randia is a Neotropical genus with ca. 90 species, belonging to the Gardenieae tribe. Unlike the Central American species, the South American ones remain imperfectly known. The previous taxonomic study of Randia in Bolivia has more than 90 years old, in which were cited only fiv...

Background and aims: Randia is a Neotropical genus with ca. 90 species, belonging to the Gardenieae tribe. Unlike the Central American species, the South American ones remain imperfectly known. The previous taxonomic study of Randia in Bolivia has more than 90 years old, in which were cited only five species, later contributions were regional checklists. The aim of this work is to perform a first taxonomic synopsis of the genus for Bolivia, in continuity with previous studies.
M&M: Classical methods in taxonomy are employed. Living and herbarium materials, original descriptions, and nomenclatural types from the Bolivian species of Randia are studied. Imperfectly known species are fully described, otherwise, are only mentioned their diagnostic characters, and comparisons with morphologically similar taxa. The new species are illustrated too.
Results: Based on the present study, 12 species of Randia occur in Bolivia: Randia altiscandens, R. boliviana, R. calycina, R. micracantha and R. obovata, were previously cited for the country, R. tayloriana and R. claesii are new species, R. mollis is a new combination of Basanacantha mollis, R. oblanceolata is resurrected as a valid species, while R. pubiflora, R. brevituba, and R. nitida are new records for the country. Based on the specimens analysed in the present study, the occurrence of R. armata for Bolivia could not be confirmed until the moment.
Conclusions: This is the first taxonomic treatment of genus Randia in Bolivia after 90 years, which represents a first step in its knowledge, however, the real number of species in the country is underestimated. Numerous specimens remain unstudied and, unfortunately, for the moment are inaccessible. |

Introducción y objetivos: Randia es un género neotropical con ca. 90 especies, perteneciente a la tribu Gardenieae. A diferencia de las especies centroamericanas, las especies sudamericanas permanecen imperfectamente conocidas. El estudio taxonómico previo de Randia en Bolivia tiene más de 90 años, y en él se citaban solo cinco especies, aportes posteriores fueron checklists regionales. El objetivo del presente trabajo es realizar una sinopsis del género para Bolivia, en continuidad con estudios previos. M&M: Se emplean métodos clásicos en taxonomía. Se estudian materiales vivos y de herbario, descripciones originales y tipos nomenclaturales de las especies bolivianas de Randia. Las especies imperfectamente conocidas se describen en su totalidad, de lo contrario, solo se mencionan sus caracteres diagnósticos y comparaciones con taxones morfológicamente más cercanos. También se ilustran las nuevas especies. Resultados: En base al presente estudio, 12 especies de Randia habitan Bolivia: Randia altiscandens, R. boliviana, R. calycina, R. micracantha y R. obovata, fueron previamente citadas, R. tayloriana y R. claesii son nuevas especies, R. mollis, es una nueva combinación de Basanacantha mollis, R. oblanceolata es restablecida como especie válida, mientras que R. pubiflora, R. brevituba, y R. nitida son nuevas citas para el país. En base a los especímenes analizados en el presente estudio, no se pudo confirmar por el momento la presencia de R. armata para Bolivia. Conclusiones: Este es el primer estudio taxonómico para el género Randia en Bolivia después de 90 años, el cual, a pesar de representar un avance en su conocimiento, aun subestima el número de especies en ese país y numerosos especímenes permanecen sin estudiar.
