Pallida pellucida prostrata. Caules $-1-pollicares tenelli pinnati, in- 
terdum ramis microphyllis pinnulati. 
Folia subimbricata late oblique semicordato-ovata, basi antica caulem 
late transeuntia, apice rotundata raro triangulari-obtusa, facie sub- 
papulosa, margine obscure crenulata, subsinuato-complicata; lobulus 
majusculus dimidium folium subexcedens ovatus inflatus, apice 
libero plerumque involuto; cellule fere minutule equilatera, 6- 
(dein 5-8-) gonee, solum folii marginem versus subquadratee, limi- 
tibus pellucidis haud inecrassatis, centro pellucide, ambitu latius- 
cule opacee, papuloso-prominule. 
Foliola magna, foliis seepe eequilata paulo breviora, orbiculata vel ovato- 
orbiculata, ad medium fere usque bifida, segmentis patulis sinuque 
-acutis obtusisve, basi subcordata, margine incurva. 
Flores monoici: 2 terminales, fere semper dichotomiales, innovationibus 
(vel altera saltem) iterum floriferis. Bracteze foliis subeequilongee 
complicato-bilobe, lobis obtusis, antico ovato-rhomboideo, postico 
multo angustiore ligulato; bracteola bracteis basi subconnata spathu- 
lato-obovata ad + anguste bifida. 
Perianthia foliis sublongiora obovato-pyriformia compressula plicato- 
5-carinata rotundato-truncata tenuirostria, carinis vix subpapu-

Andrecia ramulo tenui constantia vel ramum terminantia; bractez 
plurijugee. 
A ceteris omnibus Lu-Lejewneis foliolis magnis aliena, Huosmo-Le- 
jeuneis aflinior; ab his tamen diversa aspectu, textura, odoris absentia, 
foliis grandilobis, ete. 
Obs. In some stem-leaves of the ordinary size, the lobule is larger 
and more inflated, and contains two narrow-oval bodies—not anthe- 
ridia, but pups, either of some minute coleopterous insect or of one 
of the apide. Those I saw were battered, but I could make out they 
liad rudimentary legs.
