Pusilla viridis, siccando nigrescens. Frons prostrata suborbicularis, 
diametro 1-2, radiatim divisze, divisionibus obovato-oblongis 
rotundato-lobulatis, medio sulcé exaratis, necnon inter lobulos sul- 
catis, quasi utrinque depresso-2-3-venosis, inter venas bullatis et 
lineari-punctatis ; costa lata, cum pagina utrinque confluens, medio 
6-8 cell. crassa, subtus longe radicellosa; cellule: paginee mediocres, 
marginales 2-strate, costam versus 3-5-strate, strati supremi nu- 
cleata, interne seepius vacue. 
Flores monoici: @ antici, e lobis apicem versus orti. Involucrum breve 
cylindraceum, inferne 6-8 cell. crassum, ore truncato scariosum sub- 
integrum. Pedicellus alte exsertus. Capsula badia, involucro 5plo 
longior, tenuis, obtusa, bivalvis, columella tenui. Elateres breves 
plani, raro torti, vix unquam subspirales. Spore pro genere parve, 
angulari-globose, minute scaberule, 
Var. macrocarpa. Inv 35; caps. cum ped 40; elat -25—3™™, Paulo 
robustior, frondis divisionibus seepe subpinnatis vel ex parte dicho- 
tomis, laciniis brevibus latis crenato-lobulatis, suleato-venosa, inter 
venas valde convexa, subrotundo-punctata, strato hypodermi sub- 
cavernoso. Pedicellus capsulaque seepe longissimi. Elateres longiores, 
flexuosi, haud spirales. Spore subleevissimee—M. Guayrapurina.

Invol 2-3 x 111; caps+ped 30™™. 
A. venoso subsimilis distat florescentia dioica; fronde plana (nec sulcato- 
venosa) profunde pinnatifido-lobata, lobis szepe assurgentibus, pin- 
natis, medio 6 cellulascrassis. Elateres breves geniculati, seepe frag-

Ab Anthocerote differt capsula subsessili, vix ultra involucrum 
apice paulo emersa, fusiformi vel ovato-oblonga, seepe in fragmenta 
transversim dehiscente ; elateribus haud spiralibus, geniculatis, 
pedetentim disruptis. [‘‘ Utriculi matricales monospermi” dicit cl. 
Nees, an recte?]—Melius forsan pro Anthocerotis subgenere ha-
