1. L. officindle, L. (commo?i Gromivell, Grey Mill or Grerj 

 Milltt); stem erect very much branched, leaves broadly lance-

 Scotland. 2^^. June. 1/. — 1 to H foot high. Fl. pale-yellow. Nuts 

 whitish-brown, highly polished ; seldom more than 2 or 3 ripening in 

 each calyx. M}' friend Captain Le Hunte has submitted these seeds 

 or nuts to analysis, and obtained the following results. The stony shells 

 of 60 seeds weighed upwards of 7 grains. Heated to redness, these 7 

 were reduced to 3, of which 4-lOths of a grain were pure silica. There 

 was also a considerable quantity of phosphate of lime and iron. 



2. L. arve/ise, L. (co7-n Gromwell or Bastard Alka?iet); stem

 bent branched, leaves ovate rough with callous dots, upper ones 

 lanceolate, all fleshy and glaucous, nuts smooth. Hook. Scot. i.

Sea-coast among sand or loose stones, rare, and only in the North of 

 England : Wales ; plentiful in the north and west of Scotland. Be-

 with minute teeth at the mouth. Whole plant very glaucous ; and 

 when the blcjm is rubbed off, rough callous points appear, which become

 bles that of oysters.
