 pinnate-ramulose ; branches robust, thick and tumid. Leaves close, 

 falcate, with elongate-ovate or oblong base and short acumen, faintly 

 or not striate, more or less denticulate all around, not reflexed on the 

 borders, larger than in H. imponens ; cells very narrow, the alar (one 

 or two) large and pellucid, the other basal cells yellow ; paiaphyllia 

 few, subulate. Perigonial leaves very broad-ovate, abruptly narrowed 

 to a straight subulate point. Capsule obovate, asymetric or subcylin- 

 dric and arcuate, thick and not striate ; teeth yellow, segments oi'ange, 

 cilia short and not appendicalate; pedicel 4-5 cm. long; upper peri-
