Type locality : Sto. Domingo. Coll. Balbisius. On trees. 



Plants closely appressed, light-green or brown ; stems creeping 

 and rooting, branches short and irregular. Leaves imbricated and 

 appressed, overlapping half their length, ecostate, entire but the 

 margins crenulate with papillae ; apex rounded ; cells large, 0.013 

 x 0.018 mm., all thick and obscure ; basal cells longer and smooth : 

 autoicous : antheridia few, in a small axillary bud without para- 

 physes : archegonia terminating short lateral branches ; perichae- 

 tial leaves with acute spreading points : seta short, nearly or quite 

 immersed : capsules erect, 1 mm. long, cylindric, pale-yellow, con- 

 tracted below the mouth when dry, walls parenchymatic, thin at 

 base ; neck stomatose ; peristomes none, lid conic, apiculate ; calyp- 

 tra not seen ; spores green, smooth, 0.027-0.032 mm.

Remarkable for its resemblance to the Hepaticae, especially 

 certain species of Frullania for which it has been mistaken and 

 hence probably has seldom been collected. 



Erpodium cubense E. G. Britton, n. sp. 

 Erpodhtm domingense fide Paris Index ed. 2. 156? 



Only a few scraps selected from Charles Wright's Cuban 

 Hepaticae by C. F. Austin have been seen, so the general aspect 

 of this species is unknown, but the leafy stems are similar to those 

 of Erpodium domingense and might easily be mistaken for them. 

 The leaves, however, are smaller and more blunt at apex ; the 

 marginal apical cells are rectangular and smaller, only 0.005- 

 O.008 mm. and obscure, with small dense papillae ; the cells are 

 rhomboidal in the upper part of the perichaetial leaves and 0.008 

 x 0.0 1 3 mm. ; the capsule is sessile and quite immersed, only 0.5 

 mm. long, "with a fragmentary peristome " fide Austin; the 

 calyptra 0.25 mm. with lobed base ; spores 0.013 mm. Found by 

 Austin with Lejeunea, no. 2oig of Wright's Cuban Hepaticae. 

 Type from the Herbarium of C. F. Austin. 



Type locality ? 



This species differs from E. domingense in having leaf-cells 

 one-half the size and more dense and obscure, and in its smaller 

 and immersed capsule.
