Andreecia medio caule posita; bractez plurijuge foliis consecutive, paulo 
minores, ventricose, antheridiis jam decisis. 
Ab hac differt Nardia succulenta (Rich.: typica, sec. specimina in in- 
sula Guadaloupe a cl. Husnot et L’Herminier lecta) statura submajore, 
foliis lateraliter patentibus omnibus emarginatis, cellularum pariete ad 
angulos valide incrassato; foliolis latioribus triangulari-ovatis, seepe 
obtusis, arcuato-incurvis magis canaliculatis; bracteis basi altius adnatis ; 
perianthiis semper fere immersis, obtuse sed sat distincte trigonis, angulis 
2 posticis interne in alam plus minus latam prominulis. Calyptra tenuis. 
Capsula subglobosa, in pedicello brevi (perianthio duplo longiore) suf- 
fulta, valvulis haud raro bifidis. Nardia succulenta var. Crossiz a forma 
typica differt foliis secundis vix tam profunde emarginatis, cellularum 
pariete minus incrassato; foliolis minoribus et planioribus ; perianthiis 
sublongioribus.

Plante aspectu magnitudineque, necnon foliis bifidis, Junger- 
manice (Lophoziw) ventricosee vel sociw simillime. Caules prostrati 
radicellosi, simplices furcative, rarius ramum unum alterumve sub- 
lateralem proferentes. Folia succuba alterna subquadrata bifida— 
superiora interdum trifida—integerrima vel dente hic illic armata, 
reti mediocri. Foliola nulla. Flores dioici: ¢ terminales. Bractece 
1-2-juge, magne, plurilobee, undulato-crispatee. Prstillidia 10-22. 
Marsupium breve, obovato-globosum carnosum, ore squamulis nullis 
vel perraris et subulatis cireumdatum. Cualyptra marsupio ad 
apicem usque adnata, ibidemque pistillidiis sterilibus coronata. 
Pedicellus basi caleeolatus. Capsula oblonga (valde juvenilis solum 
visa), Androecia mihi ignota.
