390. Plagiochila Stolzii St. 



Dioica major, rigida, virens, aetate fusco-virens, in cortice 

 ceespitans, maxime intricata lateque expansa. Caulis ad 7 cm. 

 longus, irregulariter ramosus, ramis inferis parvis, furcatis, superis 

 3 cm. longis, sparsim remoteque pinnulatis. Folia caulina con- 

 ferta, oblique patula, valde decurva, postice ampliata, cristam 

 formantia, in plano ovato-oblonga, basi utrinque longe decurren- 

 tia, margine infero nudo, supero regulariter denticulato, apice 

 angusta, rotundata, dentata basi postica grosse crispata. Folia 

 ramulina caulinis similia, sequimagna, angustiora, similiter armata. 

 Perianthia oblongo-obconica, ore truncato lacerato. Folia floralia 

 caulinis similia, majora, magis armata. Cellulse foliorum superae 

 10 X 10 \L, trigonis magnis acutis, basales vix majores.
