(the Península de Nicoya) and show certain pubescence characters of stem and leaves that stray from those indicated in the Manual Apocynaceae treatment (2020). We may even be following a precedent set recently with our choice of "Centella erecta" for this feature (see Apiaceae, under "Leaps and Bounds"): our determination as M. pseudobarbata is tentative, and has not been confirmed by Manual Apocynaceae co-author Doug Stevens (MO). The plant hails from ca. 550 m in the Reserva Natural Monte Alto, and the photos are thanks to our correspondent from there, Miguel Méndez. By these photos, the Monte Alto plant appears to lack the longer (2–3 mm), patent trichomes that partly characterize the sp., as according to the Manual. Is this part of the variation in M. pseudobarbata, or will another cavalier identification be proven wrong?! We have not yet seen a herbarium specimen of this material, but Miguel has promised to prepare one.   TOP
