Contribuciones a la Pteridología costarricense. II. Plantae novae vel minus cognitae

Abstract

Four new species of Elaphoglossum Schott ex J. Sm., are described from Costa Rica: E. eludens, E. leporinum, E. fournieranum and E. valerianum. The genus is richly represented in the country. Four new extensions of geographical ranges are reported: Bommeria pedata Fourn., Trichomanes (Didymoglossum ) petersii Gray, Trichomanes (D.) gourlianum Grev., Woodwardia radicans (L.) Smith, from North and South Ameríca are now known from Costa Rica. The rare intergeneric hybrid Pleuroderris michleriana (Eaton) Maxon, last collected from this country in 1910, has been found growing between large populations of Dictyoxiphium panamense Hk., and Tectaria incisa Cavanilles.
