 Habitat in rupibus & faxis lubmarinis paffim. 

 Radix callus parvus expanfus — Fro«i fubmcmbranacea, aliquando 

 coriacea, plerumque tenuis membranacea — Stipes brevis admodum, 

 baud mora in ramos varie diviCos abit: modo frons primaria brevis, 

 indivifa, obtufa & cuneiformis eft, modo dichotoma, modo elongata 

 ramis latcralibus indivifis dichotomifque : at denique rami palma- 

 tim quodammodo dividuntur. Sa2pe frons vere palmata eft, etiam 

 fub ipfo ortu — Fru^ificatio etmn variis ludit imaginibus — Modonoa 

 Fucum ied Ulvam diceres, quippe granulis folitariis numerofiffimis 

 confpergi videtur. In plantis coriaceis fru6tificationem Fuci li- 

 cet detegere, tubcrcula fcilicet in fronde innata, apice dehifccntia 

 — Haec perraro accidunt — Magnitude biuncialis, pedalis & ultra — 

 Color ruber. 



Were not this plant extremely common, and not liable to be 

 confounded with any other, we Ihould think it our duty to draw 

 up an elaborate defcriptioh of it in all its various forms. Scarcely 

 a plant in nature varies more : as the extremity of the branches 

 iifually terminates in fomething of a pah latcd form, the effential 

 charader is taken from that circumftance. But it mufb be oblerved, 

 that it often is very backward in appearing without difguife : often- 

 times the branches are lengthened out without any divifion ; fome- 

 times they are merely dichotomous. Sometimes the frond is proli- 

 ferous, fo as to lay claim to a place in our firft divifion, foliis dif- 

 tin£fis. 



The defcription in the Fl. Scotlca perfectly coincides with our 



own obfervations. At Weymouth and elfewhere we have found It 



of a perfedly coriaceous fubftaiice, as well as the thinneft mem- 



z brane.
