Composita—Wartsia. 257 
2. W. aivrea, syn. Moina nitida.—Very near the last, with 
less pointed bracts of a golden yellow, and the flower-heads in 
a looser corymb. 
W. Steetziana, syn. W. tenélla, is a dwarfer plant with 
smaller flower-heads from pure white to a bright yellow; and 
W. nivea is very near No. 2, differing however in having 
comparatively longer florets and white or pink bracts. 
30. PODOLEPIS. 
This is another Australian genus of the same tribe. In this 
the involucral bracts are erect or not distinctly spreading as in 
the foregoing genera, and the outer florets are ligulate or 
irregular. Achenes not beaked. Pappus of simple or feathery 
bristles. Name from rods, a foot, and Xeis, a scale, from the 
scaly bracts on the peduncles. . 
1. P. acuminita, syn. Scalea ja- 
ceovdes.—Perennial, but treated as 
an annual in gardens, and growing 
about 18 inches high. Leaves 
petiolate, oblong or lanceolate, 
smaller upwards, and clasping the 
stem. Involucral bracts scarious. 
Florets yellow, exceeding the in- 
volucre. 
P. chrysantha, syn. aristata, is 
an allied species in which the invo- 
lucral bracts are terminated by a 
fine bristle. 
P. grédcilis is a more delicate 
plant with purple, lilac, or white 
florets.

31. HELICHRYSUM. 
To this and the next genus 
belong the true Everlasting Flowers 
or Immortelles, or at least those 
generally cultivated and sold under 
these names. The species we have 
to notice are all treated as annuals, Fig. 144, Helichrysum bracteatum. 
and are tall leafy plants with soli- ees 
tary large flower-heads, in which the involucral bracts are 
spreading or recurved, or clustered and small with incurved bracts.
