<p><strong><em>Beilschmiedia osacola</em> (Lauraceae) a new species from the Osa Peninsula, Costa Rica</strong></p>

Abstract

We describe and illustrate a new species of Beilschmiedia, from the Osa Peninsula of Costa Rica. It is distinguished by its small flowers, which are turbinate to campanulate, with six fertile stamens and pubescent ovary, in addition it has alternate leaves along the twigs, with the lower leaf surface glabrous and not glaucous. In the field, it can be recognized by its stature, a very large tree, with the bark reddish, and peeling in large plates. Among described congeners it is superficially similar to B. hexanthera, from French Guiana, which also has six fertile stamens, and staminodes of whorl III columnar, but differs in having a pubescent ovary and larger, more branched inflorescences.

Theobroma flaviflorum (Malvaceae: Byttnerioideae), a New Species from the Osa Peninsula, Costa Rica

“…Despite this, new records and new species are documented every year (e.g. Callejas Posada 2020; Chinchilla et al 2020; Perdiz et al 2020; Rodríguez and Santamaría-Aguilar 2020; Jiménez et al 2021; Santamaría-Aguilar et al 2021). As part of a long-term study of the floristics of the Osa Peninsula, the second author encountered an unusual Theobroma with yellow flowers and globose fruits that we formally described here.…”
