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.
