OF THE AMAZON AND ANDES. 47 



The first, and hitherto the only described species of this 

 remarkable genus was discovered by Dr. J. D. Hooker in the 

 Antarctic Islands. A. andensis shows a nearer approach to peri- 

 stomate mosses than even A. Wilsoni, for the valves of the capsule, 

 besides being more numerous, are not longer than many peristomes. 

 The calyptra is torn away at an early stage, and often remains 

 sticking to the points of the perichastium when the capsule is 

 elevated beyond the latter by the growth of the fruit-stalk. Four 

 of the capsule-valves are generally narrower than the rest, so that, 

 though I have constantly found ten valves, I should expect them 

 to be occasionally reduced to eight. The valves are from four to 

 eight cells wide at the base, the total circumference of the capsule 

 at that part consisting of about fifty-two cells.
