Folia subimbricata patula decurvo-faleata semiovata vel semiovato- 
lanceolata, subacinaciformia, abrupte acuta acuminulatave, margine 
antico toto argute muricato-serrulata, postico, apice serrulato excepto, 
integerrima, infra medium sinuato-lobulata; lobulus 2-3-plo brevior, 
in situ anguste convolutus, subcylindricus fusiformisve, explanatus 
autem subrotundus, integerrimus; cellule parvule pellucidee, pariete 
ad angulos incrassato, inferiores submajores. 
Foliola plus duplo breviora, squarroso-recurva, subquadrata (paulo latiora 
quam longa) apice lato emarginato-truncata, angulis sinuque (per- 
brevi) pro more acutis, basi rotundata, margine integerrima ; superiora 
autem, florem ? versus increscentia, denticulata vel subspinulosa, 
suprema (i.e. bracteola) fere semper integerrima, 
Flores dioici: @ terminales, innovatione suffulti. Bractezee muricato- 
spinulosz, inzequilonge, altera libera foliis zequalis oblique obovato- 
lanceolata acuta, lobulo minuto lineari-rhomboideo aucta, altera 
duplo brevior lanceolata elobulata innovationi adnata; bracteola 
suborbiculata cochleato-concava repanda integerrima. 
Perianthia obcordato-spathulata, sinu apicali profundissimo, valde com- 
pressa, postice parum convexa, opaca, margine subincrassato in- 
tegerrima. 
Andreecia (juniora) apicalia, plerumque brevispica; bractez laxiuscule, 
subineequilobee, lobulo subacuto. 
Cum L. Surinamensi intricata crescit, difficile extricanda, facilius dis- 
tinguenda: colore badio; caule minus ramoso; ramis validioribus; foliis 
crebrius setuloso-ciliatis; foliolis squarrosis semper emarginatis, superiori- 
bus denticulatis; perianthiis apice inermibus, nec subspinulosis.—L. con- 
vecistipa, Gotts., differt foliis acuminatis, foliolis rotundis, perianthiis 
apice denticulatis.—L. truncatula L. peruviane e longinquo atfinis !
