EULEJEUNEA DENUDATA Pearson, sp. nov. 
Sterilis. Medioeris pallide viridis laxe esespitosa. Caulis firmus, cellulas 
2-3 latus, remote et longe bipinnatus radieulosus, rhizoideis usque ad apicem 
dispositis, fasciculatis, divergentibus. Folia dissita vel contigua alterna 
patenti-divergentia (70?) semi-ovata vel semi-rotundata vel faleato-ovata 
integra, margine antico (inferiore) brevissime decurrente vel recto, postico 
(superiore) arcuato, ad caulis medium  attingente, basi angustä, apice 
rotundato; textura firma; cellulæ mediocres quadraiæ vel oblongo-quad- 
raiz 4—5-6-gone, trigonis nullis, quedam majores, folia tamen haud 
conspicue ocellata ; lobulus plerumque nullus, in ramis quibusdam tamen 
minutus ovalis tumidus. Foliola parva, cauli arete adpressa, quam caulis 
paulo latiora, ovalia vel subrotundata, ad 1 bifida, sinu acuto vel rotundato, 
segmentis triangularibus acutatis, «epe nullis. 
Andreecia in ramis brevibus posita.  Bracteæ in paria 4 dispositee ; lobus 
rotundatus, lobulus similis sed minor. 
Dimensions, Stems 3 to 14 inch long ; diam. of stem ‘1 mm.; with leaves 
1:25 mm. wide; leaves, lobe ‘65 mm. x 475 mm., ‘6 mm. x ‘5 mm., lobule 
‘15 mm. broad x ‘1 mm. high ; cells ‘03 mm., ‘O4 mm. x ‘03 mm., ‘04 mm. ; 
underleaves ‘15 mm. high x *1 mm. broad; perigonial bracts +175 mm. x 
175 mm. 
Obs. This is a remarkable Lejeunea ; the distantly branched stems, texture 
of the stem and leaves, the absence of lobules on the larger forms give it 
somewhat the appearance of a Calypogeia, to which genus it had been 
referred by one authority. 
It does not agree with the description of L. aloba St., Sp. Hep. v. (1915) 
767, from New Caledonia, which name had already been appropriated by 
Sande Lacoste, Hep. Jav. 1856, 72, Tab. 13, and from which it is very 
different, according to the description and figures.
