Arachis woodii (Leguminosae): a new species from the bolivian Pantanal

Based on the analysis of materials collected in botanical expeditions conducted since 2000 in underexplored regions of Bolivia, in this study we present a novel species to science: Arachis woodii. This species has been collected a few times from a single location in the western edge of the Pantanal...

Krapovickas †, Antonio Germoplasma maní silvestre Pantanal Germplasm Pantanal peanut Based on the analysis of materials collected in botanical expeditions conducted since 2000 in underexplored regions of Bolivia, in this study we present a novel species to science: Arachis woodii. This species has been collected a few times from a single location in the western edge of the Pantanal swamps, where it thrives in black shallow soil over rock outcrops. While the morphology of its vegetative organs resembles, to some extent, that of A. glandulifera and species of the K genome, a set of features differentiates it. Arachis woodii exhibits large, somewhat dorsiventrally flattened fruits with a prominent somewhat recurved beak, akin to classical elf shoes. The exocarp is dark brown and deeply reticulated. Additionally, the bristles on the lower surface of the leaflets lack a disc of glandular tissue at the base, a trait clearly distinguishing it from A. glandulifera. Chromosomal and molecular marker analyses indicate that this species does not align with any of the genome types described so far in section Arachis. Continuando con el análisis de los materiales coleccionados en expediciones botánicas realizadas en regiones poco exploradas de Bolivia desde el año 2000, presentamos una nueva especie para la ciencia: Arachis woodii. Esta especie fue coleccionada múltiples veces de una sola localidad en el borde occidental del Pantanal, prosperando en suelos negros poco profundos sobre afloramientos rocosos. Aunque la morfología de sus órganos vegetativos se asemeja, en cierta medida, a la de A. glandulifera y a la de especies del genoma K, un conjunto de características permite distinguirla. Arachis woodii presenta frutos grandes, algo aplanados dorsiventralmente, con un pico prominente, similar a los zapatos clásicos de los elfos. El exocarpo es marrón oscuro, profundamente reticulado. Además, la superficie inferior de los folíolos tiene cerdas sin un disco de tejido glandular en la base, un rasgo que la distingue claramente de A. glandulifera. Los análisis cromosómicos y de marcadores moleculares indican que esta especie no pertenecería a ninguno de los tipos genómicos descriptos hasta el momento para la sección Arachis.
