 si|)honii et nudi nut dr-inum ad yonicula fasciati, slratoquo cellularum 

 corlicalium instrucli; plurimi dccidui, nonnulli increscentes, corlico

 23 divaricates ant rotrorsum uncinatos excurrentes; mucrones 

 subliyalini. Cellultc corliealcs minutae, subrectanjjulaj aut hoxaodne, 

 donium majjis irregularcs. Articuli ramellorum diamotro tcquales 

 aut 2 Gplo longiorcs; in ramulis ramisque broviores; in illis 

 endocliromate colorato lincli, in liis mine monosiphonii, nunc (in 

 ultimis speciebus) ipsi cellulosi. 



Cystocarpia transfonuationo ramuli formata, in pcdunculo brevi 

 terminalia ramcllisquc brcvioribus paucis involucrata. Pericarpiimi 

 rotundatuin aut transvcrsalitor oblongum bi-trilobum, collulis angu- 

 latis subhyalinis conflatum, clausura, cellularum dissolutione [?] de- 

 mum apertum. Nuclei plures eodom pericarpio inclusi, circa pla- 

 centam centralem dispositi. Placenta centralis pcdunculum continuans 

 et ad apicem cystocarpii (stepe inter lobos subinflatos depressum) 

 extensa, filis densis dicliotomo-fastigiatis et anastomosibus conjunctis 

 conlexta. Ab Iiac columua contrail cystocarpii fila, ramorum ad 

 instar, exeunt, quoquoversum radiantia, plurima elongata sterilia, 

 alia breviora fertilia; sterilia subrejjulariter dichotoma, arliculis 

 clongatis constantia, in cellulas periphericas pericarpii desinenlia; 

 fertilia fascicules plures ad di versos lobos tendentes formantia , 

 juvenilia paniculato-ramosa, arliculis brevibus oblongis constantia,

 Gemmidia divisione iterata articulorum orta, oblong demumquo 

 mutua pressione angulata, muco solidescente invicem separata atquo 

 in unum coliibita. Fila sterilia nucleolos ita foruiatos circumcirca 

 auibiunt. Fasciculi lilorum gemmidia matura continentes alii<jue 

 juveniles, aut forsan ad evolutionem non pervenientes, intra idem 

 pericarpium sa)po adsunt.
