Habitat in rupibus et faxis marinis paflim. 



Radix, callus expanfus, qui autem in plantis provectioribus fxpe 

 conoideus, ligni inftar durus — From cartilaginca valde ramofa com- 

 prefla, ramis ramulifque diftichis alternis, 1 — 4 pcdalis, glaberrima — 

 Rami ramulique modo valde diftantes, modo conferti. Ad latera 

 ramorum ramulorumque folia oriuntur, difticha omnia, plana,

There is no need of labouring the description of this plant, as 

 it in fact has no rival ; its pod-like leaves or proceiTes being a pecu- 

 liar dift.in&ion. 



We were furprifed to find at Weymouth large plants of this 

 fpecies thrown up by the fea entirely void of all fructification, or 

 indeed any approaches to it; the leaves being lengthened to a very 

 considerable degree, and exceedingly narrow and thin. 



The procefTes which we call leaves, after fome time thicken and

 older ones to be holiow, cellular, and void of feeds. Thofe placed 

 towards the extremities of the branches are cartilaginous and folid,
