The Cutting Edge

Volume XIII, Number 4, October 2006

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

Nowadays, new spp. and country records often involve the most unprepossessing plants.  How else to escape detection for a century or two?  This quarter’s Pick may hold little horticultural appeal, but we love it anyway.  The depicted sp., currently known to us as “Forestiera sp. A” (Oleaceae), was first collected by Manual co-PI Barry Hammel over 15 years ago near the southern tip of the Península de Nicoya.  That collection, with immature fruits, was ultimately determined by a family specialist as F. rhamnifolia Griseb., but suspicions soon arose.  Barry’s repeated return trips in search of mature fruits and flowering material finally paid off this year, and the evidence at hand appears to verify that an undescribed sp. is involved.
