brana praealta, ultra medium dentium producta, processus in 
carina late hiantes, cilia solitaria vel bina, plus minus elongata,

Resembles in habit W. gracilis De Not., but much stronger, with a very 
different areolation of broad and short cells. The leaf areolation recalls that 
of the genus Muiobryum Limpr., but the stomata of the capsule are super- 
ficial and the annulus is quite distinct. 
Webera Debati Card. & Thér., sp. nova—Laxe cespitosa, 
lutescenti-viridis, habitu philonotideo. Caulis 1.5-2.5°™ altus, 
inferne dense radiculosus, inde tomentosus, innovationibus gra- 
cilibus erectis. Folia inferiora sat remota, erecto-patentia, supe- 
riora magis conferta, appressa, circa 1.3™™ longa, 0.33™™ lata, 
lanceolata, acuta, basi haud decurrentia, marginibus planis toto 
fere ambitu denticulatis, costa basi 40 crassa, sub summo apice 
evanida, cellulis mediis linearibus, 140-170" longis, 28-304 latis, 
inferioribus latioribus brevioribusque, rectangulis vel subhexa- 
gonis, marginalibus longioribus, anguste linearibus. Caetera 
ignota. Plate XX.

This species seems closely connected with W. annotina Bruch, from which 
it is distinguished by the larger size, the habit resembling that of a small 
Philonotis, the tomentose stems and the leaves plane on the margins.
