five acute-pointed leaves. It is a native of Canada, flowering from 

 June to August. 



The second species differs from the first, in having the leaves 

 ovate at the base, and a little attenuated, and more villose under- 

 neath. It is a native of North America, flowering from July to 

 September. 



The third has a perennial root the stems about two feet high, 

 smooth, acute-angled: the leaves indented on the edges, on very 

 short foot-stalks; when bruised they emit a very grateful refreshing 

 odour : towards the top of the plant come out two or four small 

 side branches, with smaller leaves of the same shape: the flowers 

 are produced in large heads or whorls at the top of the stalk, and 

 there is often a smaller whorl at a joint below the head: and out of 

 the head arises a naked peduncle, sustaining a small head or whorl : 

 the flowers are of a bright red colour. They come out in July; and 

 in a moist season, or when the plants grow in a moist soil, they con- 

 tinue till the middle or end of September. It is a native of North 

 America. 



The fourth species resembles the following, but the leaves are 

 longer, smooth, wrinkled a little like those of Sage, and the flowers 

 white. It is a native of North America, flowering from July to 

 September. 



The fifth has stems about two feet high, branching out from the 

 bottom to the top: the leaves lanceolate, coming out in clusters at 

 each joint, where there are two larger leaves, and several smaller 

 ones on each side ; the larger leaves are two inches and a half long, 

 three quarters of an inch broad, and slightly indented on their edges: 

 towards the upper part of the stem the flowers come out in large 

 whorls, with an involucre to each whorl composed of ten or twelve 

 small lanceolate leaves, of a purplish red colour on their upper side 

 (four larger, and four smaller, besides the leaves of the whorls): the 

 flowers are pretty large, of a dirty yellow colour spotted with purple. 

 It is a biennial plant; and a native of Maryland and Virginia, 

 flowering here from June to October.
