JUNCACEAE. Juncus liebmannii J. F. Macbr., mentioned in the Manual as expected in
Costa Rica (having been collected in western Panama, as well as Mexico and Guatemala), has
turned up in the flesh. The specimen in question (E. Alfaro 3726) hails from the fabled
Valle del Silencio, high on the Atlantic slope of the Cordillera de Talamanca, just a
stone’s throw from the nearest Panamanian locality (Cerro Fábrega). Thanks and a
tip of the hat to INB’s resident volunteer, Ted Bradley [see The Cutting Edge 12(3): 1, Jul.
2005], for this determination.
SAURURACEAE. A mystery plant collected by INBio’s Luis Acosta at ca.
1300 m on the Atlantic slope of the Cordillera Central in Parque Nacional Braulio Carrillo
has been identified by Manual co-PI Barry Hammel as Houttuynia cordata
Thunb., an Asian sp. that is sometimes grown as an ornamental. Although none of us has ever
seen it planted in Costa Rica, it is, by all accounts, naturalized and quite well established
at the Braulio locale. Barry was able to recognize the sp. because of his acquaintance with
it at MO, where it thrives in the English Woodland Garden next to the Lehmann Building.
According to our criteria for inclusion in the Manual, Saururaceae will have to be treated
formally and in full (bother!). Thanks to Francisco Morales (INB) for this
SCROPHULARIACEAE. Bacopa lacertosa Standl., formerly known only from southern
Mexico, Belize, and Nicaragua, can now be reported from Costa Rica on the basis of
Espinoza 2398. We do not presently have access to the field data, but the
collection is presumably from somewhere in the Guanacaste region.
