PLAGIOCHILA. 499 
Perianthia campanulata, ore prelato obliquo longispinoso-ciliata, hinc 
alata, ala spinulosa. 
P. deflexirama Tayl. (a JAMESON in M. Pichincha lecta) ramis pinnatis 
ac in nostra gaudet, differt autem absentia foliolorum, et foliis dimidiato- 
ovato-oblongis. P. abietina Nees, satis superque distincta foliis plus 
duplo miuoribus, toto fere margine dentatis et ciliatis, necnon foliolorum 
absentia completa.

Caudex prostratus ramosus, foliis denudatus, multicaulis. Caules 3-polli- 
cares, imbricati, arcte bipinnati, plumam ambitu lanceolatam fin- 
gentes, pinnis cujusque lateris usque ad 20, apice decurvulis ; alii 
basi in plumam bi-tritidam divisi. 
Folia conferta patula semiovata-cordatave obtusata vel rotundata ; margine 
antico concavo recurvo apicem versus bidenticulata; postico toto 
fere apiceque breviuscule argute spinuloso-denticulata, dentibus sub 
15, basi integerrima caulem imbricantia et ssepe recurvo-cristata ; 
cellule minutulz zequilateree opacee. Flores non aderant. 
Pl. thyovdes differt caule simpliciter pinnato; foliis longe decurrentibus, 
margine postico minus dentatis, basi crispulis ; denique preesentia foliol- 
orum. Pl. montana (inter Frondescentes) elatior est, frondem triangul- 
arem sistens ; foliis longioribus magis dentatis, cellulis majoribus. 
Obs. Species iste tres ultime foliis basi recurvo-cristatis certe cum 
Cristatis conveniunt, e ceteris caracteribus autem habituque melius forsan 
inter Frondescentes collocavissent.

basi postica ampliata, apice pro more ineequaliter bidentata, in aliis
