The Cutting Edge

Volume XXII, Number 3, July 2015

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

SEASON'S PICK: This season's poster child Campuloclinium macrocephalum (Less.) DC. (Asteraceae) is sort of a "Leap and Bound" that got away from us.  The first and (until recently) only collections known so far from Costa Rica were made by former parataxonomists way back in 1991 (Rivera 1584) and 1993 (E. López 77), but not correctly determined until several years later (1997 and 1996, respectively).  Those specimens hailed from both slopes of the Cordillera de Guanacaste, at 600–700 m elevation.  In mid June of this year, Universidad de Costa Rica student and frequent contributor to this rag Esteban Jiménez recollected the sp. from savannas at Rincón de La Vieja and sent us these fine photos.

Esteban had also collected this sp. a year or so earlier on the slopes of Volcán Miravalles.  We find it interesting that this rather widespread savanna sp. (TROPICOS shows it from Mexico, Honduras, Costa Rica, Bolivia, Brazil, Paraguay, Uruguay, and Argentina) has not been collected in either Nicaragua or Panama, where appropriate habitat would seem to abound.  The photos are vouchered by J. E. Jiménez & Herrera 2866 (USJ).
