 3. H. chloroneura ; caule laxe csespitoso, debili, procum- 

 bente, subramoso ; foliis laxis, tenuibus, patentibus, ob- 

 longis, acutis, serratis, binerviis ; seta scabra, brevissima, 

 flexuosa; capsula inclinata, turbinata ; operculo recto, 

 rostrato. — On Pichincha, near Quito, Prof. William

Only a single specimen occurred ; but the diminutive fruit,

 calyptra is entire, laciniated at the base and descends as far 

 as the mouth of the capsule.
