 slightly recurved, oblong, rounded at the apex, acute ; margins 

 recurved ; nerve excurrent as an apiculus. Areola : Upper 

 small, roundish ; lower quadrilateral. Perichcetial leaves erect, 

 very small, broadly ovate, acuminate. Fruit acrocarpous.

 its small size is easily overlooked. 



33. T. arida, sp. nov. Plate XL., fig. 33. 



Plants perennial, monoecious, growing in dense tufts, dark- 

 brown, £ in. high. Branches arising from near the base, fasti-

 hyaline point at the apex ; margins entire ; nerve stout, 

 continued to the apex ; crisp when dry. Areola : Upper 

 small, dense ; lower quadrilateral. Perichcetial leaves erect, 

 shorter and narrower than the upper ones. Fruit acrocar- 

 pous. Fruitstalk red, |- in. long. Capsule cylindric, gibbous. 

 Operculum nearly as long as the capsule, conico-rostrate ; beak 

 long. Peristome single, twisted ; teeth one-third longer than 

 the tube. Calyptra large, cucullate.
