We present and illustrate a new species of Myoxanthus from Costa Rica, closely related to M. scandens. We present descriptions and illustrations of both species. The new species, Myoxanthus sotoanum differs from M. scandens, by its linear leaves, the brownish-yellowish flowers, the yellow petals and lip, the oblong, obtuse, subfalcate lateral lobes of the lip, the two keels extending nearly to the middle of the lip, and the shorter, triangular, acute teeth that flank the stigma. Myoxanthus sotoanum generally also occurs at lower elevations than M. scandens.; Presentamos e ilustramos una nueva especie de Myoxanthus para Costa Rica, junto a la descripción e ilustración de M. scandens basadas en material costarricense. La nueva especie, Myoxanthus sotoanum, es similar a M. scandens, de la que difiere principalmente por sus hojas lineares, las flores café-amarillento, los pétalos y el labelo amarillos, los lóbulos laterales del labelo oblongos, obtusos y subfalcados, las dos quillas que se extienden hasta la mitad del labelo y los dientes más cortos, triangulares, agudos, que flanquean el estigma. Myoxanthus sotoanum generalmente se encuentra a elevaciones inferiores que M. scandens.

The establishment in Costa Rica of the great naturalist Charles H. Lankester in the 19th century brought a tremendous increase in the knowledge of Costa Rican Orchidaceae. His desire to leave the collections kept at his farm for a scientific and educational purpose was finally accomplished in 1973 with the foundation of Lankester Botanical Garden (JBL). Since then, JBL has followed Lankester’s legacy with its consolidation as a leading center for the study of Neotropical orchids, resulting among others in more than 180 new Costa Rican species and records in the last 12 years. This manuscript includes the description of four new species and seven new records, as part of JBL’s contribution to the completion of the Costa Rican orchid inventory.

The new species Stellilabium smaragdinum is described and illustrated from the montane oak forests of the Cordillera de Talamanca, Costa Rica. Among the species of Sect. Taeniorhachis, S. smaragdinum may be recognized for the inflorescence bearing 1-3 (4) simultaneous flowers, the oblong to ovoid, rounded basal lobules of the lip, the non-ciliate margins of the lip midlobe and the peculiar colour of the column setae, cream banded with purple.; Se describe e ilustra Stellilabium smaragdinum de los bosques montanos de encino de la Cordillera de Talamanca. S. smaragdinum se distingue de otras especies de la sección Taeniorhachis por su inflorescencia con 1 a 3 (4) flores simultáneas, los lóbulos basales del labelo oblongos a ovoides y redondeados en el ápice y la peculiar coloración de la setas en los lóbulos laterales de la columna, marfil con bandas púrpura.

Lepanthes gerardensis from north-central Costa Rica is described and illustrated. It is most similar to the Mexican L. ancylopetala Dressler, from which it differs in shorter habit, petiolate leaves with broadly elliptic blades, and different lip shape. It appears to be a specialized twig-epiphyte.; Se describe e ilustra Lepanthes gerardensis, de la parte central norte de Costa Rica. Es semejante a L. ancylopetala Dressler de México, de la cual difiere en el hábito menor, hojas pecioladas con láminas anchamente elípticas y forma del labelo diferente. Parece ser una epífita de ramitas, especializada en ramas terminales delgadas.
