CERATO-LEJEUNEA. PAS : 
utriculum majusculum dilatatus; cellule parvule pellncide, 2v. plures 
exteris duplo majores juxta folii basin in lineam occellumve congeste. 
Foliola dissita foliis 2-3-plo, in pl. 2 spe 4-plo minora, suboblato- 
orbiculata, adusque v. paulo ultra 4 bifida, segmentis acuminulato- 
acutis, sinu lato acuto, margine supra medium pauciserrulato raro 
integerrimo. 
Flores dioici: 9 in ramo brevi terminales, innovatione simplice suffulti. 
Bractez foliis zquilong bipartite, lobis lanceolatis acutis, crebre 
spinuloso-serratis, inferiore duplo angustiore et subbreviore; brac- 
teola minor ovali-lanceolata fere ad 4 bifida, serrulata, segmentis 
acuminulatis, basi utrinque cum bracteis connata. 
Perianthia subemersa urniformia subcompressa alte 4-carinata, carinis 
papulosis apice in cornua lata brevia recurvulo-patula—rarissime 
clausa oblonga compressa—plerumque plus minus evoluta, obconica, 
ore hiante inzequaliter lobulata crenatave, dilatatis. 
Andreecia in ramis terminalia, vel ramulum totum tenentia, robusta; 
bractez 5-jugze, foliis 2-plo breviores, imbricatze turgide. 
L. Filaria Tayl., ad Esmeralda a cl. JAMESON lecta, quoad folia valide 
dentato-serrata et foliorum segmenta acuminata nostree similis, differt 
foliis “rotundis obtusis.” 
L. Brasiliensis Gottsche, Syn. Hep. 398, facie et foliolis subserratis 
nostre similis, certe distincta est foliis solum apicem versus serrato- 
spinulosis ; foliolis magnis ad } solum bifidis, et perianthiis longicornibus. 
L. platyceras, quoad caules pinnatos et folia argute serrata L. plumule 
haud dissimilis, differt floribus dioicis ; lobulis plerisque inflatis (parvis 
tamen); foliolis multo majoribus subserratis; perianthii cornibus patulis 
plerumque evolutis, etc. 
Obs, Utricles—not very large—are present at the base of a few 
of the branches, but their place seems to be mostly supplied by 
several (rarely all) of the leaf-lobules on certain branches becoming 
more turgid, although not longer, than in the normal state. Any 
tenants these sacs may have contained have disappeared from my 
specimens.
