whole of Jussieu's System. In that of Linnaeus, however, 



a portion of these naturally co-ordinate plants, from having 

 two of the four stamens imperfect, have been excluded 

 from the Class Didynamia, which comprises the bulk of 

 them, and in critical strictness included in Diandria; among 

 these is the present genus. The features which characterize 

 the genera throughout this natural tribe, are, a monope- 

 talous bilabiate corolla, four single-seeded germens con- 

 nected at the base by the style, and fruit which abides 

 within the persistent calyx. Each fruit consists of four 

 'om miscarriage sometimes fewer) dry one-seeded peri- 

 carps, adhering in such manner to the integument of the 

 seed as not to be discriminated from it* Every such peri- 

 carp, with its contents had been till recently deemed a 

 naked seed ; but is now included, bv Mr. Brown, in the 



term cariopsis, appropriated by Monsieur Richard to the 

 kind. 



Punctata is a tolerably hardy perennial plant, native of 

 North America, where it is found, according to Mr. Pursh, 

 in sandy fields, in the tract of country which reaches from 

 New Jersey to Carolina. Its most conspicuous ornament 

 consists in the pink bractes, which form the involucre 

 beneath each whorl of the inflorescence. The yellow co- 

 rolla, when inspected near, will be found thickly spec- 

 kled with small resinous dots, and variegated, or rather 

 marbled, with pink stains. We do not know the exact 

 height the plant may reach, but have never seen it more 

 than a foot and a half high. The bloom smells like that of 

 the common Balm ; the foliage more like that of Mint. 

 The teeth of the orifice of the calyx ultimately spread 

 into a small star. The imperfect stamens are filaments 





without anthers. The anthers of the perfect stamens divide 

 into two vertically divaricate lobes. The style is villose, 

 with two simple setiform stigmas of very unequal lengths. 



Cultivated in this country in 1714, by Mr. Thomas 

 Fairchild.

 flowered in the nursery of Messrs. Lee and Kennedy, at 

 Hammersmith.
