Foliola dissita subsquarrosa foliis 2-3-plo breviora, oblato-orbiculata 
subcordata, apice incuryo fere ad } bifida, segmentis acutis acuminu- 
latisve, subcrenulata. 
Flores dioici: 9 in ramo terminales, innovatione suffulti. Bracteze foliis 
breviores, erecta, undulato-crispze, ad 4 complicato-bilobe, grosse 
denticulate v. subspinulosz, lobis lanceolatis subacuminatis sub-

denticulata. 
Forsan a L. tnvoluta G. Syn. Hep. 350, diversa, cui adsunt folia “ ovato-

bracteis connata. Species heece dus transitum ad Strepsi-Lejeuneam et 
Harpa-Lejeuneam prebent. 
Suspcenus XX.—HARPA-LEJEUNEA, &. 
Plantee pusille pallide virides, post siccationem difficillime emollite, 
depresso-ceespitosee. Caules tenues, tenaces tamen nec facile rupti, 
arete repentes, vage v. subpinnatim ramosi, ramis seepe assurgentibus 
apice decurvis. 
Folia laxiuscula seepissime divergentia hamataque v. saltem fornicato- 
concaya (solum in L. spinulzflora subplana) oblique ovata, longiora 
quam lata, plus minus acuminata, raro obtusa rotundatave, integer- 
rima v. celluloso-crenulata serrulatave, leevia, v. cellulis (superioribus 
precipue) obtuse acuteve prominulis exasperata, lobulo majusculo 
turgido, rarissime obsoleto, aucta; cellule parvee v. etiam preeminute 
(go-aym™) seepius leptodermes, subpellucide, in aliis speciebus pauce 
suprabasales ceeteris majores subvacue ocellum sistentes. 
Foliola minuta foliis 3 -7-plo minora, vel (in Cardiostipis) cuneata obeor- 
dato-emarginata bifidave, segmentis rotundatis, vel (in Cyclostipis) 
rotunda, ad } bifida, segmentis acutis obtusisve—in unica sp. integra. 
Flores in Cardiostipis omnibus dioici, in Cyclostipis plurimis monoici: 9 
in ramo brevi terminales, innovatione plerumque simplice, raro 
iterum innovante, suffulti, rarissime dichotomiales. Bracteze lobu- 
late, raro complicate, solum concave carinateque (in Cardiostipis 
ad carinam alatee) integerrime v. celluloso-crenulate-serrulateve, 
rarissime denticulate; bracteola angusta biloba—in paucis sublatior 
et truncato-retusa-emarginatave. 
Perianthia seepe pro plantula maxima, 2-3-plo longiora quam lata, pler- 
umque pyriformia, parum compressa, 5-carinata, carinis levibus v. 
celluloso-scabris, in paucis spinoso-alatis, brevirostria. 
Andrecia amentulis cauligenis folium proximum subsuperantibus con-

Hab. In sylvis opacis humidis, tam planitiei quam montium, in cortice, 
rarius in foliis vivis et in truncis putridis, fere constanter aliis hepaticis, 
Frullaniis et Lejeuneis preecipue, irrepentes.
