The suddenly insidious Asystasia gangetica (L.) T. Anderson subsp. micrantha (Nees) Ensermu continues to make news in Costa Rica. Right after our initial report (see this space in our last issue), Manual co-PI Barry Hammel found it growing in the Mariposario of the Museo Nacional, in downtown San José. More recently, Península de Osa botanical overlord and friend Reinaldo Aguilar encountered a population in a vacant lot in Puerto Jiménez. During this lull in legitimate country records, we’ve decided to attempt to document what appears to be an explosive expansion in Costa Rica of this so-called “sleeper weed”. CONVOLVULACEAE. CR curator Joaquín Sánchez and others at the Museo Nacional have found Itzaea sericea (Standl.) Standl. & Steyerm. on the Atlantic slope of Costa Rica, SE slope of Fila Muchila (in the Valle de Estrella, northern foothills of the Cordillera de Talamanca, southwest of Puerto Limón). This is a significant range extension for a sp. that until now was known in Costa Rica only from the central Pacific slope (Cerro Turrubares, Valle Central, and P.N. Carara)—if at all! (see “Germane Literature” under “Davidse” et al.). MELASTOMATACEAE. Manual collaborator José González (LSCR) reports the first collection from the Estación Biológica La Selva of Miconia argentea (Sw.) DC. This sp., though dirt common on the Pacific slope of Costa Rica, is of only scattered occurrence on the Atlantic slope (though it has been collected at slightly higher elevations in the Sarapiquí vicinity). This record was garnered by Enrique Salicetti, as was the following (also reported by José). MYRTACEAE. The cultivated Manzana rosa, Syzygium jambos (L.) Alston, can now be added to the flora of the Estación Biológica La Selva (as all cultivated taxa customarily are, even if represented by just a single individual). TOP
