Has. St. Domingo. Dickson. 1814. 



Patches loose, olive-green. Stems 3-4 inches long, irregu- 

 larly pinnate, the branches subpinnate, deflexed. Leaves by 

 no means imbricated, the cauline rather broader than long, 

 their margins flexuose, their apices obtuse, they are sinuate 

 at their junction with the lobule: this lobule is singular in 

 the genus, for it sends obliquely down, after it has crossed 

 the stem, a 'waved oblong process, more than twice as long 

 as the lobule itself, and which partly embraces the stem. 

 Thus the lobule reminds one of the auricle of the leaf of 

 Fmllania Mans, L. et Lind. I have inscribed this species to 

 my friend, who has devoted his superior talents to the suc- 

 cessful illustration of the Jungermanniea.

 integerrimis j calyce axillari, sessili, ex angusta basi cam- 

 panulato, compresso, ore subintegro.
