FABACEAE. A couple of minor, in-country range extensions have come to light in recent months. Manual co-PI Barry Hammel collected good material of Teramnus volubilis Sw. from near his weekend digs in Cabuya, at the southern tip of the Península de Nicoya. Said sp. has been collected just a few times in Costa Rica, and was reported in Manual Vol. 5 (2010) only from "bosque muy húmedo" on the Atlantic slope and southern Pacific slope. This new collection (see images at Hammel’s Flickr pages) extends the range northward on the Pacific slope, and into "bosque húmedo." Because of its small size, tiny flowers, and apparent seasonality (it may even be an annual), Barry suspects that T. volubilis is actually far more common in Costa Rica than herbarium records suggest. While rummaging in Fabaceae at CR, Barry redetermined Aguilar 5900, from near Buenos Aires in the southern Valle de General, as Vigna longifolia (Benth.) Verdc., a sp. previously known in Costa Rica only from the northern half of the country, albeit on both slopes. The new locality, in "bosque húmedo," nicely bridges the ones reported in the Manual, which were suspiciously disjunct habitat-wise between the "bosque seco" and "bosque muy húmedo" life zones The Aguilar specimen was originally determined as Vigna vexillata (L.) A. Rich. which, it appears, may no longer be said to occur in the Valle del General (although it has been collected elsewhere in "bosque húmedo").
