The Cutting Edge

Volume XXIV, Number 2, April 2017

News and Notes | Leaps and Bounds | Germane Literature | Season's Pick

SEASON'S PICK: This time around let's go with two again, one the lowly Cleome rutidosperma DC. (Cleomaceae), the other the grand Cordia megalantha S.F. Blake (Boraginaceae).

The few known Costa Rican specimens (Burger et al. 11873; Hammel & Pérez 27321; Kriebel 2708) of this sp. are all from the south slope of Volcán Barva or nearby, above 1400 m elevation, and almost in cloud forest—not the sort of place one might expect to find this African introduction (a true Cleome sensu stricto), otherwise known from relatively low elevations. Could it be that we got the determination wrong!?

Thanks and a tip o the hat to co-PI Nelson Zamora, for sending us (just in time) these fine photos of Cordia megalantha, straight from the field, vert. Carib. of Volcán Rincón de la Vieja, where he reports the species is in an explosion of flowers at this very moment!
