CALYPOGEIA. 449 
CALYPOGEIA EUTHEMONA, Spruce. 
Hab. ad aggeres umbrosos, in montis Tunguragua radicibus, juxta pagum 
Baiios, alt. 1800™. 
Caulis sectio 6 x°3;. f 1:°3x°9, 3™™; mvol ‘5™™ latium. 
Pusilla viridis prostrata. Caules }-pollicares, sat lati, compressi, cellulis 
pluristratis conflati, radicellis crebris prelongis arcte adrepentes, 
simplices vel e floris 2 basi postica recte innovando-continui, raro 
ramum unum alterumve proferentes, flagellis nullis. 
Folia tenerrima confertissima, opposita basique antica subconnata, assur- 
gentia, oblique ovato-oblonga, apice recurvulo rotundata rarius retu- 
sula, angulata vel obsolete 2-3-loba ; cellule: mediocres leptodermes 
parum elongate, chlorophyllose, inferiores subposticee majores et 
vacue. 
Involucra 2 (juvenilia) terminalia truncato-conica, bracteis 3-seriatis, 
in annulos 3 angustos imbricatos connatis ; annulus extimus textura 
foliorum, ore repandus integer vel subtrilobus ; 2 interiores breviores 
tenuissimi, ore inequaliter plurifidi lacimative.  Pistillidia 12 
brevia cylindracea, receptaculo convexulo insidentia.—Cztera haud 
visa. 
Caulis infra florem 2 subgibbosus valde radicellosus, itaque in mar- 
supium serius deferri procul dubio videtur.—Lindigina Liebmanniana 
Gottsche, Mex. Leverm. 120 t. 20, differt foliis multo latioribus. In icone 
late ovata depicta sunt, obovata autem in textu descripta. 
XXVI. PLAGIOCHILA, Dum. 
Recueil (1835); Lindenberg, Sp. Hep. (1839-1844); Radule 
subdiv. 3, Plagiochila Dum. Syll. (1831). 
Plante speciose, plerumque elate, interdum pedales, raro pusille, 
cxspitose vel inter muscos reptantes. Caudex validus prostratus, 
subtus radicellis crebris pallidis rufisve matrici adfixus, vage divisus, 
foliis lateralibus brevibus truncatis demum marcescentibus sparse 
vestitus, hic illic caules erectos, assurgentes, horizontales, interdum 
pendulos proferens. Caules validi, rufi vel fere nigri, raro pallidi, 
cellulis angustis pluristratis, exterioribus stratorum 3-5 coloratis, 
internis pallidis, conflati, subzequifoliati vel e foliis inferioribus 
parvis truncis dissitis dendroidei, arhizi vel rarissime ad ramos radi- 
cellosi; plerumque dichotome ramosi, in aliis autem pinnati; rami 
omnes laterales, e folii axilla sepius juxta angulum posticum orti. 
Folia omnium fere magna, interdum maxima (1-8™™ longa) sat lata 
et pro more integra, colore varia, raro rosea, succuba, ad lineam 
anguste parabolicam, antice longius quam postice decurrentem, cauli 
adfixa, distiche patula vel devexo-secunda, in aliis opposita, in aliis 
plurimis alterna, obliqua, spe quasi-dimidiata, axi excentrico 
margini antico multo magis approximato quam postico; apice raro
