Badia late dense implexo-cespitosa. Caules 1-2-pollicares, seepe tota 
longitudine matrici arcte adhzerentes, vage subramosi, ramique sepe 
valde ramulosi, ramulo perbrevi, paucifolio, 9 v. neutro, e folii fere 
cujusque axilla egrediente, eidemque subzequilongo. 
Folia confertissime imbricata late oblique semicordato-ovata, apice valide 
decurvo rotundata, margine supero incurvulo appressa, infero leniter 
recurvulo ante lobulum profunde sinuata; lobulus fere 4-plo brevior 
ovalis subbifidus, segmento inferiore majoreque subrotundo apice 
cucullato, superiore parvo rhombeo subplano; cellule parvule pel- 
lucidee, ambitu opacee, rotundo-hexagonz, pariete incrassato. 
Foliola late imbricata foliis fere equimagna, sed fere duplo latiora quam 
longa, a basi breviter cuneato-decurrente reniformia, apice late 
retusa, margine toto recurvula cellulisque parvis uniseriatis subopacis 
marginata, basin versus facie interna foveolata, externa umbonata, 
et ex umbone radicellas fasciatas, apice parum divergentes. pro- 
ferentia. 
Flores dioici: @ ramulis brevissimis insidentes quasi-laterales innovatione 
parva suftulti. Bracteze foliis subduplo breviores, obcordato-bilobee, 
complicate, lobis subzequalibus, v. antico paulo minore, obovato- 
trapezoideis; bracteola minor oblonga apice bifida bidentatave. 
Obs. The short ramuli are usually female, rarely neuter. In some stems 
they spring from nearly every leat-axil, and each bears a Q flower, with 
only 1 or 2 (rarely more) pairs of minute leaves beneath it. Adnate to 
the outer bract, springs an innovation, at a very acute angle, bearing few 
smallish (but not minute) leaves. The bracts are complicate and so 
shortly bifid that they are best described as obcordate, with a deep sharp 
emargination. In the outer bract (which widely imbricates the inner) the 
upper (antical) lobe is very slightly the smaller, leaving a narrow rim of 
the lower lobe visible all around the free edge, when the two are pressed
