354mm, 
Pusilla pallide viridis, strato tenui late effusa. Caules }-1-pollicares, 
prostrati virides opaci validiusculi subteretes, minute radicellosi, e 
facie postica parum ramosi, ramique seepe apice attenuato subaphyllo 
radicantes, flagellis propriis autem nullis. Cellule in caulis dia- 
metro sectione 7 vel 8; externze (corticales) pluri-(ad 22-) seriate, 
opacee incrassate ; interiores externis equimagnee vel etiam latiores, 
__ leptodermes pellucidee. 
Folia contigua vel subdissita, patulo-recurvula rarius subassurgentia, 
suboblique obcordato-rotunda obovatave, ad insertionem obliquam 
vel fere longitudinalem paulo angustiora ; cellule minutule, quad- 
rato-rectangularive-hexagonz, subopacie, centro pellucide, endo- 
chromio parco, extus parum prominule verruculoseque. Foliola 
nulla. 
Flores monoici: ¢ vel ramulo brevi proprio, e caulis facie postica 
exeunte constantes, vel ad spicam ¢ axillares: nempe ramulum e 
bracteze ¢ axilla ortum sistentes. Bractee 92 vix plures quam 
bijuge, foliis caulinis subequilongee, recurvo-patule ovales breviter 
bifidee—subinde trifide vel bis bifidae—lobis acutis, hine vel utrinque 
cum bracteola lanceolata ligulatave basi connate. 
Andreecia amentis posticis, seepe incurvis, semper fere ramosis, constantia. 
Bractez primariz sub 12-jugze, foliis duplo fere minores, orbiculate 
concave raro retusze, Julaceo-imbricate ; bracteolee nulle ; antheridia 
solitaria. Rami sunt alii fceminei ; alii neutri quorum folia (s. 
bractez steriles) erecto-reflexa canaliculato-equitantia, elongata, 
oblonga, apice obcordata bifidulave. ; 
Stirps singularis, facie formam Odontoschismatis Sphagni parvulam 
mentiens, flagellorum defectu distincta. Florescentia quasi-gynandra 
etiam in Cephalozia bicuspidata interdum invenitur.
