 Frondes usque 4-pedaIes, pennne corvinae inferne crassitiem ^equan- 

 tes, tamen a caule arreptas descripsit clarus Agardh. Rami gemini 

 ssepissime approximati et ad idem latus flexi, rarius discreti, plu- 

 ries ramulosi. Foliajuniora et inferiora linearia, integerrima. sub- 

 ecostata, 2.5 cm. vix longa; superiora magis filiformia; horum infra 

 apicem oritur vesicula singula, petiolo longo plano aut compresso 

 sulfulta et apiculo lineari-subulato coronata, e sphserico ellipsoidea. 

 Receptacula a foliis terminalibus formata, pedicello 4-6,5 millim. 

 longo insidentia et fere fequilongo apiculo saepe inflato terminata, 

 7-8 millim. longa, verrucosa, cylindracea.
