Granada, 2075 , and Jameson's, from the Andes of Quito, 1 847. Our 

 plants are larger than Lindig's, the capsules longer and the pedicels 

 single. The leaf is broadly undulate, ending in a short cusp, the 

 marginal cells short, quadrate and papillose, the basal cells oblong 

 and hyaline. The basal membrane of the peristome is very short, 

 the teeth twisted once, white and granulose. Bescherelle says of 

 this: " Folia ad basin margine recurvis, cellulis inferioribus simili- 

 bus differe mihi videtur. 7. fragilis (N. Grenada, Lindig, 2075) 

 folia basi plana, ab cellulis marginales inferiore minores ut margi- 

 nata habet : an Z! /hr^z/zj' forma peculiaris?"

Compared at Kew with Spruce's nos. 185, 194,* 197, 200-202 

 Andium Quitensium. Also verified by M. Bescherelle.

Compared with no. 130 Spruce, And. Quit., with which it 

 agrees. 



Macromitrium Rusbyanum E. G. Britton, n. sp. Unduavi 12000 



ft. October, 1885 (3188). 



Plants large and showy in yellowish-brown tufts; stems 9-10 

 cm. long, repeatedly branching ; leaves brown, broken and abraded 

 on the lower parts of the stems, light yellow, longer and spirally 

 twisted at the tips of the branches, 5-9 mm. long, lanceolate-lin- 

 ear, from a broader yellow or brown base, margins finely serrate 

 above, vein ending in the channelled apex; lower cells elongated, 

 porose ; upper, shorter with thick protruding walls. Dioecious? 

 Seta twisted or arcuate, 5 mm. long, stout ; capsule almost globose, 

 2 mm. long, walls smooth and thick, brown and shining; lid conic- 

 beaked ; peristome double, outer, a thick fleshy membrane^ inner, 

 short, fragile, with bright yellow smooth teeth ; calyptra, not seen ; 

 spores large, .0810-.0864 mm. 



This is one of the handsomest species collected by Dr. Rusby 



and was dedicated to him by Dr. Mliller, but referred to a new 



genus allied to Leptodoiitiinn ; but after careful comparison 



at Kew with specimens of Macroinitriuni tricliopJiyllinn Mitt., 



and M. scopariiini Mitt., I have concluded that its alliance is with 



these species. The absence of the calyptra is unfortunate, but in 



all other respects the likeness is very close, and the alliance is 



concurred in by William Mitten, to whom specimens were sent.
