Type locality: Sto. Domingo. Coll. Balbisius. On ta*ees. 



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, O.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; perichac- 

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

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

 tracted below the mouth when dry, w^alls parenchymatic, thin at 

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

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



On trees in Sto. Domingo, Porto Rico and Hope Mines near 



Kingston, Jamaica, Z. M. Underivood 4., 24 January, 1 903. 



Remarkable for its resemblance to the Hcpaticae^ especially 



certain species of FntUania for which it has been mistaken and 



hence probably has seldom been collected. 



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



Erpodmni domiiigense 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 Erpodhim 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- 

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

 rhomboldal in the upper part of the penchaetial 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 '' y?^/^ Austin; the 

 calyptrao.25 ^"^- with lobed base; spores 0.013 mm. Found by 

 Austin with Lejeunea, no. 20 ig of Wright's Cuban Hepaticae. 

 Type from the Herbarium of C, F. Austin. 



Type locality ? 



This species differs from E. domingense \n having leaf-cells 

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

 and immersed capsule.
