The Cutting Edge

Volume XXVI, Number 4, October 2019

Mortoniella pittieri Woodson (Apocynaceae), submitted only a few days ago by Manual co-PI Nelson Zamora, gets its moment of fame in this season's pictorial essay. The photos were taken in the northwesternmost corner of the country, on the road between Playa Pochotes (Bahía de Salinas) and Conventillos, by Zamora and vouchered by his number 10613 (CR).

Mortoniella pittieri Woodson (Apocynaceae)

The species is very localized in CR, known here only between Bahía de Salinas and just across the (very low) divide into the Atlantic slope in the basin of the Río Sapoá.  It is confusable with the much more widespread Plumeria rubra L., but can be distinguished in a number of ways, but perhaps most easily by its conspicuous colleters, located about where the last traces of leaf blade disappear on the upper surface of the petioles (clearly visible in these photos).
