The plant now defcribed includes the two fpecies oi fafligiaius' 

 and furcelLuus of Hudlon and Lightfoot — and fafiigiatus and /2 of 

 Withering. But as the fafligiatus and furcellatus of Linnaeus are 

 now known to be different plants from either, we have thought it 

 proper to give the name of lumbricalis to this fpecies, after Gmcliii 

 and the firfl: edition of Flora Anglica. 



The late Mr, Lightfoot doubted whether his /^/^/Ww ^nAfurcel- 

 latus were diflintSt ; and we have pofitive proof that they are not to 

 be confidered even as varieties, having in our pofTeifiona fpccimea 

 gathered from the beach at Yarmouth, in which both 'are fecn 

 arifing from the fame root, and in which the dichotomy of one 

 branch aftually exhibits both forts. This difcovery has made it 

 very difficult properly to defcribe this plant, the terminations be- 

 ing fo very different under thefe varying circiimftances. It feems 

 however probable, that what has been called fafigiatus has not 

 really any frudlification;.for though thefe oval terminations have on 

 their concave fide a mucilaginous appearance, no feeds are ever ob- 

 ferved in them : but when the fwelling forks of the other are in a 

 mucilaginous flate, the feeds imbedded ia the mucilage are very ap- 

 parent. 



Tills fpecies differs from radlalus'in its fibrous root, the very acute 

 angles of the ramification, and in its fwelling pod-ljke extremities.
