Resumen
Estudios recientes sobre la flora de los páramos en Costa Rica, revelan dos nuevas especies endémicas
taxones descritos aquí como Gaultheria paramicola A. Rojas y Vaccinium reptans
A. Rojas, ambos conocidos sólo de Costa Rica y Panamá. Las primeras especies nuevas se han confundido con Pernettya prostrata (Cav.) DC. (=Gaultheria myrsinoides Kunth), sin embargo debido a sus hojas mucronadas sin secundarios visibles
venas y frutos blancos a rojos está más emparentada con G. mucronata (L. f.) Hook. &
Arn., una especie sólo conocida de Chile y Argentina pero que se diferencia porque es
hermafrodita (vs. monoica), plantas relativamente más cortas, hoja laminar más corta,
corola más corta, frutos más pequeños, mayor distribución altitudinal y diferente distribución geográfica. La segunda especie nueva ha sido confundida con Vaccinium consanguineum Klotzsch y V. floribundum Kunth pero difiere de
tanto porque tiene porte procumbente (vs. erecto), hojas ovadas (vs. lanceoladas),
frutos pruinosos (vs. no o pocos pruinosos) e insípidos (vs. agridulces) con
cáliz suberecto (vs. adpreso) (excepto en V. floribundum).
Recent studies on the flora of paramos in Costa Rica, reveal two new endemic taxa described here as Gaultheria paramicola A. Rojas and Vaccinium reptans A. Rojas, both known only from Costa Rica and Panama. The first new species have been confused with Pernettya prostrata (Cav.) DC. (=Gaultheria myrsinoides Kunth), however due to its mucronate leaves without visible secondary veins and white to red fruits it is more related to G. mucronata (L. f.) Hook. & Arn., a species only known from Chile and Argentina but differs because it is hermaphrodite (vs. monoecious), relative shorter plants, shorter laminar blade, shorter corolla, smaller fruits, higher altitudinal distribution and different geographical distribution. The second new species has been confused with Vaccinium consanguineum Klotzsch and V. floribundum Kunth but differs from both because it has procumbent (vs. erect) habit, ovate (vs. lanceolate) leaves, pruinose (vs. not or few pruinose), and insipid (vs. bittersweet) fruits with suberect (vs. appressed) calyx (except in V. floribundum).
