Leith and New-Haven^ &c. VIII. 

 The leaf is flat, about three inches long, fimple 

 at the bafe, but greatly dilated upwards, and 

 ■- • dichotomoufly branch'd ; the branches about 



one-eighth or one-tenth of an inch wide, and 

 "' ' bifid at the extremities. 



The color is a pale green ; the fubftance membra- 

 naceous, very thin and pellucid, and when exa- 

 min'd with a microfcope appeaijs to be finely 

 -^■' ■ ■ reticulated; the mefhes nearly fquare, and run- 



ning in longitudinal lines contiguous to each 

 other. 

 The feeds are fmall and brown, and fcattered 



throughout the whole fubftance of the leaf. 

 From the reticulated texture of the membrane, 

 we at firft imagin'd it might belong to the clais 

 of Zoophytes, and be rank'd in the genus of 

 Flujlra. Lin. but upon a more attentive exa-
