PRIONO-LEJEUNEA. 159 
Perianthia pro plantula magna, foliis fere triplo longiora, anguste obcor- 
dato-cuneata, apice profundiuscule emarginata brevirostria, margine 
supra medium inzqualiter spinulosa, spinulis 3-4 cell. longis basi 
1-3 cell. latis, antice subplana, postice obtuse unicarinata con- 
vexave, 
Andreecia rami apicem—raro totum—tenentia; bracteze 4-6 juge. 
L. leptocardia folia habet duplo longiora, pro ratione angustiora, facie 
insigniter muriculata ; foliola duplo majora ovali-rotunda; perianthia 
tamen breviora foliis caulinis perpaulo longiora, distincte alata, minus 
profunde emarginata—Anne pro L. microdonte varietate habenda L. 
macrocardia 2? Statura minor, foliola minuta, preecipue autem perianthia 
magna distincte obcordata margine valide spinulosa vetant.

Folia pro plantula magna subimbricata, late semiovata, fere semicircularia, 
abrupte acuta, obtusa, rotundatave, a basi constricta sublongitudinali 
antice valde dilatata, utraque facie (basin versus except4) margineque 
toto (basi postica excepta) argute celluloso-muriculata, infra medium 
recte complicata, plica subhorizontali; lobulus 3-plo minor semi- 
ovatus inflatus, apice occulto, interdum obsoletus; cellule parvule 
subequilaterze conico-prominul, basin versus tamen longiores sub- 
plane. 
Foliola foliis 4-plo minora, caule parum latiora, ovali-rotunda, ad vel 
paulo ultra medium bifida, subintegerrima. 
Flores monoici; @ in ramo perbrevi longioreve terminales, innovatione

vel altera parvilobulata; bracteola brevior ovali-lanceolata, ad medium 
bifida, rima angusta, segmentis acutatis. 
Perianthia altiuscule emersa anguste obcordato-cuneata, valde compressa, 
postice obscure unicarinata, supra medium ala pellucida 3-4 cell. 
lata serrulata crenulatave utrinque marginata, exindeque ad speciem

Andreecia brevia vel subelongata, ramulum totum sgepius tenentia; brac-

Ab hae certe differt L. microdonta foliis levibus sinuato-complicatis, 
lobulo subbreviore turgidiore; bracteis distincte labulatis; bracteola solum
