Species of uncertain affinity ; not clearly referable to any of 

 the described subgenera. 



193. H. Wrightii, Sulliv. Monoecious : plants loosely 

 intricate, dark green or variegated with reddish yellow; stems 

 prostrate, radiculose on the lower side, irregularly divided; 

 branches long, loosely foliate: leaves two-ranked, coniplanate, 

 ovate-oblong, blunt or acute at the apex, obscurely serrulate 

 above, the lateral spreading with an oblique base, indexed on 

 one side ; costa stout, ascending to above the middle ; areolation 

 rhomboidal-oval, slightly tumid on both sides ; alar cells very 

 numerous, small, transversely oblong, close ; perichgetial leaves 

 few, loose, erect, costate to the middle, narrowed into a slender 

 serrulate point : capsule small, oblong, erect or slightly cernuous, 

 thin, narrowed to a short pedicel ; operculum conical, short- 

 roslrate ; teeth pule-yellow, distantly articulate ; segments cleft ;

 Mexico (Feiidler). 



A distinct species, not to be confounded with any oilier. In its suberect 

 capsule and oblong' seuii-costale and coniplanate leaves it resembles the 

 genus UoDialia, to which it was originally referred, and the figure is 

 still retained in the plates as representing sufficiently the characters of 

 that genus. 



194. H. planum, Brid. Monoecious : plants widely ces- 

 pitose, stems prostrate, very long-creeping, complanate, irregu- 

 larly pinnate, bright green : leaves loosely imbricate, broadly 

 ovate, acute or shortly acuminate, concave below, constricted at 

 base; borders erect, minutely crenulate; costa obsolete; cells 

 long, narrow, pajnllose, the basilar few, quadrate, granulose, the 

 alar three, small and vermicular, pellucid ; perichastial leaves 

 sheathing, broad at base, lanceolate-subulate, erose-denticulate 

 above, more strongly papillose : capsule small, subcernuous, 

 oval and horizontally inclined, constricted at the orifice, short- 

 necked, on a very long yellow smooth pedicel ; operculum tur- 

 gid, conical-acuminate, orange; teeth yellow; segments solid, 

 as long; cilia solitary, Avhite. — Muse. Recent. Suppl. ii. 97;
