Dr. _William Stephens_, Botanic Professor in _Trinity College, Dublin_, in his Examination declared, that they grew in great Plenty about _Dublin_, and in several Counties he had observed great Quantities, chiefly on Mountains, and barren Places: That, they were easily to be propagated, in almost any kind of Soil, and that he had some flourishing in the Physick Garden, belonging to the University. The Resolutions, that the House entred into _January 10_, might very well have sufficed to have recommended a General Practice. But to remove some Prejudices and to obviate some false Representations, I have impartially recited the several Facts and Testimonies, on which they were founded. That all People may easily know and find out these Plants, I shall here give a Description; which though tedious, I hope will be excused. _Cinquefoil_, in _Latin_, _Pentaphyllum vulgare_, in _Irish_, ~Tuigbeag~ (_Tuigbeag_) ~Tuigvear Muirre~ (_Tuigvear Muirre_) and in some Counties, ~Meagigh~, (_Meagigh_) is a Plant, whose Roots are very long, about a Finger’s Thickness, of a dark brown or reddish Colour, and very astringent in Taste; the Leaves are born at the Extremity of a small Stem, five together, deeply indented on their Edges, of an oblong Form and hairy; on the Grand Stem, at the Nodes, shoot forth several smaller, terminating with a small Yellow Flower, composed of six small Leaves surrounding a Number of Threads, from whence ariseth a Cluster of Seeds. It flourishes in every Hedge, sandy, loose and deep Soil: the Roots which are to be preferred, are the thick, long, and of the darkest Colour. _Tormentil_, or _Septfoil_, in _West Meath_, called ~Neauhnadis~ (_Neauhnadis_) in _Ulster_, ~Menedin~ (_Menedin_) or ~Neauhnid~ (_Neauhnid_) in _Connaught_, ~Levenet~ (_Levenet_) in the County of _Mayo_, ~Fenede na Muc~ (_Fenede na Muc_) this Plant, hath a thick, tuberous Root, of a reddish brown Colour, sometimes covered with a black Skin, of a very astringent Taste, and shooting out many Fibres; the Leaves are generally seven, set on the Extremity of a Foot Stalk, of a dark Green Colour, deeply indented on the Edges and hairy, from amidst them ariseth several small weak Stalks, of a reddish Colour, and hairy, about 12 or 18 Inches in Height, knotted; at every Knot, or Joint, is a Foliage, and two or three Foot Stalks, some bearing Leaves, and one longer than the rest the Flowers consisting of four Leaves, of a light Yellow Colour, to which succeeds the Seeds; the flower Cup, hath Eight Leaves, four large and four small, the Root when Vigorous sends forth several Runners, the Stalks of which are of a reddish Colour, and hairy that spread over the Ground; at every Joynt, from one Part ariseth two or three Stems, each bearing at the Extremity five Leaves, from the other Part, descend several Fibres that become Roots.
