Howe : Notes on American Hepaticae 287

The Long Island specimens agree essentially with those from 

 Georgia and Florida, though the latter make a slightly closer ap- 

 proach to the Cuban plant. The Long Island station is therefore 

 a noteworthy northward extension of the known range of a plant 

 which has heretofore figured in papers on North American Hepati- 

 cae as coming only from a limited region of the South. The arche- 

 gonia in these United States specimens, so far as we have observed, 

 always occur on a short postical branch. The leaves are 5-8 cells 

 long ; the underleaves are 3- or 2-parted, their prongs of 2 or 3 

 cells each, incurved at the apices. All are autoicous. In the orig- 

 inal Jungcnnannia nematodes, collected in Cuba by Wright, the 

 leaves are 0.25-0.5 mm. long, 4-6 cells high, the cells being 2-3 

 times longer than broad. 



The variety longifolia often gives the impression of being two 

 or three times the size of the Cuban plant, but we have been unable 

 to find any reliable structural characters to serve for a specific 

 separation. The form of the perianth seems quite variable in all 

 conditions of the species, but is often broader in the var. longifolia 

 than in the type. 



No. 180 Hep. Am., issued as Blepliarostoma nematodes, is ref- 

 erable to Telaranea nematodes longifolia ; it is mixed with Cepha- 

 lozia connivens and with a minute Lepidozia, probably a reduced 

 form of L. setacea.

This plant, though a close relative of T. nematodes, seems en- 

 titled to specific distinction, differing in the almost invariably 2- 

 parted leaves, in the frequent continuation of the stems into leaf- 

 less flagella (rare in T. nematodes) and in the simpler 9 bracts. 

 It is described by Stephani as dioicous, though apparently he had 

 not seen $ plants. We have been unsuccessful in attempts to 

 find antheridia in the specimen kindly communicated by Herr 

 Stephani, and it certainly may be suspected that dioicism is to be
