 Note. — PI. Tasm. ii., 229. Although the perfect torus of 

 this species {Gymnanihe cinerascens) is wanting, there are 

 sufficient indications present in the specimens to warrant its 

 being placed in this genus. The stipules, overlooked in the 

 description of the plants in the " Synopsis Repaticarum," are 

 nevertheless present as well in the specimen kindly con- 

 tributed by Dr. Lehman, as in those gathered by Mr. Gunn, 

 but they are not obvious on all the stems, and are thus 

 easily overlooked. The involucral leaves scarcely differ in 

 form from the cauline, but are concave, and enclose four or 

 five pistils seated on the dorsal side of the abrupt and 

 slightly thickened apex of the stem itself; within the 

 involucre there has been observed a small stipule-like 

 leaflet, but not apparently representing i\\Q stipule, which, 

 although present, has no part in the formation of tlie torus 

 in the plants of this and allied genei'a. PL xvi.
