[Botany • 2023] Columnea blancoi (Gesneriaceae) • A New Species from the Central Pacific Region of Costa Rica


Columnea blancoi J.E. Jiménez, Chinchilla et Kriebel,
 
in Jiménez, Chinchilla et Kriebel, 2023.

Abstract
We describe and illustrate a new species of Columnea from the Central Pacific region of Costa Rica. Columnea blancoi sp. nov. is morphologically similar to Columnea canarina, from Panama which it can be distinguished by having stems that are flaky and sericeous distally, ovate bracts, entire, green and shorter calyx lobes, yellow corolla that is glandular-pilose externally, with a marginal purple-red line 1–2 mm wide on all lobes internal and externally, and a shorter ventral corolla lobe and style. A taxonomic description, illustrations, a distribution map, conservation status, and comments on how C. blancoi differs from other morphologically related species are provided.

[Botany • 2023] Pleurothallis pugio (Orchidaceae: Pleurothallidinae) • A New Species from Costa Rica


Pleurothallis pugio Karremans & J.E. Jiménez,  

in Karremans et Jiménez. 2023. 
 
Abstract
A new species of Pleurothallis is described from Ciudad Quesada in Costa Rica. The novelty belongs to Pleurothallis series Acroniae Luer, having a close floral affinity with P. dentipetala and P. rowleei, from which it can be easily distinguished by the two-flowered inflorescence branches, bearing tiny yellow flowers with ovate-lanceolate, undulate dorsal sepal, decurved, oblong-lanceolate, dagger-like petals, and an ovate lip. Pleurothallis pugio is reminiscent of P. imitor, a species which also has two-flowered branches bearing yellow flowers. However, the latter is only known to occur in Monteverde Reserve at higher elevations, and differs in the petals that are only slightly decurved, with an entire margin, the sepals that are elliptic, and the lip that is triangular-sagittate.
