simili habitu (Meteoriis, Phyllogoniis, etc.) perseepe consociata ; rarius 
etiam ad filices. 
Distr. Species paucee nobis cognitee inter tropicos totius orbis vigent. 
Tpse in Andium Quitensium et Peruvianorum devexis sylvaticis 4 
species solum legi, quarum una, Fr. atrata Sw., a Mexico et ins. 
Antillarum ad Brasiliam australem dispersa est. 
Obs. Melius forsan pro subgeneris sequentis sectione habenda, differt 
autem a Thyopsiellis cladocarpicis caule indefinite elongato, foliis basi 
utrinque cordatis (nec solum antice semicordatis) caule circumvolutis, et 
foliolis angustis. 
The few species composing this group inhabit only the dampest hill- 
forests in tropical America, growing on rocks and the branches of trees, 
from which one of them, Jr. atrata Sw., depends in huge masses, 
sometimes half-a-yard long, and too bulky to be grasped in the arms. 
Its black-purple hue is often relieved by the admixture of mosses of 
similar pendulous habit, especially bright-green Meteoria, and silvery or 
golden Phyllogonia. It is found from the West Indies and Mexico to 
Southern Brazil and Peru, but I never met with it (nor with any other 
of the group) in the plains; wherefore I suspect that it has been 
erroneously indicated as growing on the Amazon and Orinoco. 
With Meteoriopsis might have been combined the cladocarpous species 
of the following subgenus (Zhyopsiella) ; the latter, however, differ in 
the definite stems and consequently more compact habit ; in the semi- 
cordate leaves (not equably cordate, or auricled on each side of the base) 
which are not convolute when fresh ; and in the much larger and wider 
underleaves, with recurved or reyolute margins. Otherwise, along with 
Meteoriopsis, they might rank as a mere section of Thyopsiella.
