whole of Jussieu’s System. In that of Linnzus, 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 
(from 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, by 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 ahalf 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.
