Drymonia decora J.R. Clark & J.L. Clark, sp. nov.*—TYPE: COSTA RICA. San José: Refugio de Vida Silvestre Boracayán, Fila Costeña, San José-Puntarenas Province border, ca. 10 km E of Dominical. Southern Fila Tinamastes in the region of the Catarata de San Luis near Cuesta Yeguas, in cloud forest along ridge, canopy 30 m tall with emergents to 40 m, epiphytes abundant, 9°15.5´N, 83°45´W, 1000 m. 31 May 2003, living plant cultivated at Marie Selby Botanical Garden (accession no. 2003-0412, J.R. Clark et al. 478); flowered in cultivation, 21 March 2006, B.K. Holst 8878, (type SEL).

Etymology.  The epithet is from the Latin “decorus” meaning “graceful” and is in reference to this species’ characteristic pendulous habit, not commonly seen in other species of Drymonia.

Comments.  Drymonia decora is the most recently discovered of now 24 species of Drymonia recognized from Costa Rica (Kriebel, 2006; Kriebel-Haehner, 2006). Drymonia decora can be easily distinguished from other species of Drymonia by its strictly pendulous habit and also in the gland-tipped pubescence of the calyx. These characters readily differentiate D. decora from the superficially similar D. submarginalis Gómez-Laurito & Chavarría in that the latter is neither pendulous in habit nor is the inflorescence glandularly pubescent. Similarly, D. decora is in marked contrast to the vegitatively similar species D. peltata (Oliver) H.E.Moore, that has a characteristic upright, branching habit; leaves of D. decora, although occasionally subpeltate, are not fully peltate as is always the case in D. peltata.
