Vetch Taigjonia. Anglis. 



Upon rocks covered with little earth, but not com- 

 mon. We gathered it once only, near the 'Tar- 

 ■ > het of CayitirCy on the confines of Knapdale. VI. 



The leaves are about a quarter of an inch long, of 

 an inverted heart-lhap'd figure, growing prof- 

 trate in a clump together. Their upper fur- 

 ' face is green, covered with numerous minute 

 whitifli papilU, with a hollow dot in the head of 

 ' '^ ' each •, the under furface is black, with downy 

 white radicles, by which it adheres clofe to the 

 ■ ground. The fubftance of thefe leaves is tough 



and opake, and very like that of the Marchantia. 

 ■' ■ When dry their edges turn upwards, and almoft 

 • hide the upper furface, fo that the plant appears 



all black. 

 The frudification grows at the great end of the 

 leat, on the under fide, and confifts of two 

 concave valves, or hemifphercs, of a reddifh 

 black colour, encjofing a chocolate-colour'd 

 globule, relcnibling the feed of a tare or vetch, 

 fuii of a yellow powder. 

 The leaves are proliferous, and encrcafe by Ihoot- 

 in-^ out young offsets from their fides, like the 

 animai called a Polype.
