Tenella, pallide viridis rufulave, prostrata. Caules fragiles }-}-pollicares 
subramosi. 
Folia dissita v. subimbricata; pro plantula magna, angulo axiali a caule 
atente, subconcava, a basi angusta subtransversa oblique suborbicu- 
ata, dimidio inferiore bis complicata ; plica (duplice) lanceolata- 
fusiformi, utrinque acuta, margine abscondito, arte tamen explicato 
apice exciso-bidentula ; cellule parvule equilateree subconformes 
pellucidee parum chlorophyllosee, pulchre incrassate, trigonis 8-12 
In cujusque cellule ambitu valde conspicuis, fere plang vel con- 
vexule. 
Foliola duplicata, increscentia, folio 4—2-plo breviora, subimbricata, cuneata 
v. cuneato- obovata—superiora majora subquadrata—basi rotundata, 
apice ad }-4 bifida, sinu late triangulari, segmentis patulis anguste 
triangularibus subacutis, fascia radicellarum medio dorso gerentia. 
Flores monoici: 9 in caule ramove, spe iteratim innovando-prolifero, 
terminales, erecti. Bractez foliis breviores, vix ad 4 usque compli- 
cato-bilobze, lobis subeequalibus lineari-oblongis obtusis retusulisve; 
bracteola anguste oblonga ad 4 bifida, laciniis acutis conniventibus. 
Perianthia foliis longiora fusiformi-oblonga subcompressa prealte 5- 
carinata (carinis aleeformibus), apice subrotundato tubulo perbrevi 
amplo aucta, levissima. Calyptra perpaulo brevior duplo angustior 
anguste ovali-fusiformis. Capsula globosa. 
Amenta ¢ ramulo, folio caulino sublongiore constantia-—raro in ramo 
terminalia—ovato-linearia; bracteze 6—8-jugee, foliis sat minores, 
equitantes, cymbiformes, lobo obtuso, lobulo paulo minore acuto. 
L. reflexiloba G. (Hep. Novo-Granat.); nostre ob folia margine bis 
introflexa sat similis, distincta est foliolis ovato-lanceolatis et bracteola 
apice integro rotundata retusave. 
The leaf is folded in at the postical margin, from the base to the 
middle, and the fold again folded in along its axis. Within the inner 
fold I often find one or two small globular reddish grains, without any 
apparent appendages. They are either eggs or the corpses of a Rotifer, 
like Philodina rosea.

Cum Diplasio-Lejeunea convenit foliolis duplicatis, differt foliis lobo infe- 
riore (nec superiore) majore, apice elongato in clavam cornuve con- 
voluto, marginibus superne v. liberis v. connatis ideoque sacculum 
verum efformantibus. Cellule mediocres leptodermes subpellucide 
convex planzeve. 
Foliola sepius divergenti-biloba (ac in Dzplasio-Lejeunea), raro solum 
apice bidentata basi autem sagittato-biauriculata. 
Bracteze 9 minutz integre szpius retusze. 
Perianthia campaniformia, apice convexo primum clausa, demum hiantia, 
superne 5-carinata, carinis apice in cornua brevia conica subhorizon- 
talia dilatatis.
