(879.) H. Canatiense, Kindb. Bull. Torr. Bot, Club, XVII., 280. 



Intermediate between H. imponens and H. subimponens. Dioecious. 

 Densely caespitose, yellow or pale-green. Stems creeping, densely 

 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 ; paraphyllia 

 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 orange, 

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

 chetial leaves erect. This species seems to be confounded with H. 

 imponens.
