Robusta prostrata virescens, siccando rufo-badia vel fuscidula, floribunda ; 
caules 2-pollicares valde et subfastigiatim ramosi. 
Folia opposita subimbricata (basi ad 4 lat. solum, apice sat dissita) tri- 
angularia apice lato suboblique truncato bispinosa, spinis seepe sub- 
divergentibus, sinu subrectangulari raro latiore vel lunulato; cellule 
majuscule subzquilaterze leptodermes, endochromio in annulum 
tenuem opacum coacervato. 
Foliola foliis 4plo fere breviora, caule sublatiora, cuneato-quadrata,

acuminatis, internis divaricato-bifidulis. Bracteze bracteoleeque 
exteriores intimis sensim subminores, parum diverse. 
Perianthia foliis vix duplo longiora lineari-oblonga alato-triquetra, alis 
sub 4 cellulas latis, antica trispimosd, lateralibus solum repando-

Var. elongata, 3-4-pollicaris, pauciramea pauciflora, sicca rufa. Folia 
opposita vel solum per paria approximata. Foliola latiora quam 
longa, 4-partita, sinu medio lato lunulato, laciniis divergentibus 
zquilongis, vel seepius extimis sublongioribus. Flores seepe in ramo
