not (perhaps for want of novelty to recommend it) found a

upper districts, and was introduced by Mr. Puitip Miiier. 
{t flowers from August till October; when the cold and 
frosts cause it to perish down to the root. 
Descr. Stem erect, straight, rigid, five to six feet high, 
glabrous, striated, branched, especially upwards, and there 
in a paniculated manner. Leaves opposite, on short peti- 
oles, the lower ones generally more or less bipinnate, be- 
coming pinnate upwards, and the uppermost deeply tripar- 
tite, when they pass into the simple bracteas of the peduncle, 
all of them glabrous, somewhat rigid, spreading or recurv- 
ed, of a dark green colour, the segments quite entire, of a 
linear-lanceolate form, but varying somewhat in width in 
different individuals. Panicle trichotomous. Peduncles 
with linear bracteas. Involucre glabrous: outer of seven 
to eight, linear, obtuse, spreading, green scales: inner of 
as many close-pressed, ovate, brownish, and somewhat 
membranaceous ones. Florets of the ray yellow, at. first 
singularly involute in the margins, and entire at the extre- 
mity, but soon unfolding and becoming bi- trifid at the 
apex. Disk purple: base of the tubular corolla only 
yellow: Anthers and filiform segments of the style dark 
purple. Achenium compressed, slightly winged at the mar- 
gin, especially upwards, but quite destitute of awns.
