BROMELIACEAE. In just under the wire for our monocot volumes is Tillandsia
elongata Kunth, widespread from Mexico to Peru, Brasil, and the Antilles, but
never yet collected in Costa Rica. That is, not until it was found by Manual
Bromeliaceae contributor Francisco Morales (INB) along the Río Sapoá,
near Peñas Blancas, hard up against the Nicaraguan border. Chico's material
corresponds to T. e. var. subimbricata (Baker) L. B. Sm., virtually as
widespread as the sp.
CYPERACEAE. Gómez-Laurito 10855, from near Los Chiles on the
northernmost Atlantic coastal plain, has been determined by family specialist
Konraed Camelbeke (GENT) as Scleria lacustris C. Wright. The collector
(also a Cyperaceae specialist) subsequently confirmed this identification from a photo
of the type. As far as we can determine, S. lacustris is (or was?) a Cuban
endemic, though it has become sporadically naturalized in other tropical and
HALORAGACEAE. This is more of an update than a true “leap.“ Previously
[see The Cutting
Edge 8(2): 5, Apr. 2001], we reported that Jorge Gómez-Laurito (USJ)
had collected a sp. of Myriophyllum, “probably M. aquaticum (Vell.)
Verdc.,“ from near El Empalme on the way up to Cerro de La Muerte. We speculated
that this might be a new genus and even a new family for the country. Manual aquatic
plants contributor Garrett Crow (NHA) recently sent us a scanned image of
Crow 6136 (NHA), a 1984 collection of M. aquaticum from a roadside ditch
near Santo Domingo de Heredia (this was in the days before INBio). He also suggests
that Jorge's collection may instead represent Myriophyllum quitense Kunth, a sp.
of higher elevations. If so, then we would have a new record after all.
PHYTOLACCACEAE. Phytolacca meziana H. Walter has been considered a sp. of
northern Mesoamerica, and was not included in William Burger's 1983 Flora
costaricensis treatment of Phytolaccaceae (Fieldiana, Bot. n. s., 13: 199–212).
Nonetheless, according to recent studies by Francisco Morales, it is present on
both slopes of the Cordillera de Talamanca at 2000–3150 m elevation. Checking
TROPICOS, we learn to our surprise that MO savant Ron Liesner has been applying
this name to material from Costa Rica and western Panama since at least 1996, and that
the sp. had been collected in Costa Rica as early as 1967 (by present MO Director
Peter H. Raven). Phytolacca meziana is distinctive in its long-pedicellate
fruits with a persistent calyx.
