ing towards the base, having sparse teeth on llie niargin, ami 

 sinuses between ; these leaves are set with scattered white 

 hairs, rather stiff, separated in the form of cirrhi at the ex- 

 tremity. The lengtli of tlie leaves is at most that of a finger, 

 the breadth about three lines. At the side, not in the centre, 

 of this plot of leaves, there arise several round stalks, either 

 quite smooth, or having their under suriace furnished with a 

 few scattered hairs, of a reddish colour below, a small or great 

 span long, of the thickness of a thread, and carrvi ng single 

 flowers. The flowers, before blossoming, are pendant. The 

 calyx is smooth, or slightly ciliated, simple, divided into eight 

 or ten pieces, and furnished at the base with some small short 

 scales. The calyx has as many corners as parts. 



The flower consists of an indeterminate number of uniform, 

 yellow, tongue-shaped florets, whicli are penetrated longitu- 

 dinally by five fine parallel veins (Vid. 2G0. II. Brown in 

 meinen. Neuen Entdeckungen, i. 1G6.), and the upper end 

 of which terminates in five teeth, between which run those 

 veins or nerves. The ray-florets, or those on the margin, 

 are of a lead or copper colour on their lower surface. In 

 each of the florets is a cylinder of yellow antherac, tlie fila- 

 ments of which are ciliated, remote, and inserted into the 

 lower tubular part of the floret. Through the middle of the 

 cyhnder of antherae proceeds the pistillum, which terminates 

 above, in two linear stigmata, internally warty, outwardly 

 furnished with small hairs, (Collectores, vid. 273.) At first 

 the pistillum is included in the cylinder of anther.^ ; after- 

 wards the former comes forth, and its stigmata become ex- 

 panded, and revolute. The pollen is spherical, set round 

 with fine spines, (271.) The nectary is the up{X'r part of 

 the germen, within die pappus. The receptacle is full of 

 very fine cavities, set with extremely delicate bristles. The 

 seed is longish, brown, sulcated, having cross ridges, and a 

 varying pappus: For the ray-florets bear seeds the pappus 

 of which consists altogether of short chaffy leaves ; the setnis 

 in the centre, on the contrary, have a pinnated pappus. The 

 seed is a caryopsis, in which the evolved embryon stnmh 

 erect, without albuminous matter.
