2. W. aurea^ syn. Morna 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. tenella, 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. PODOLBPIS. 



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 TTOVS, a foot, and XgTrtV, a scale, from the 

 scaly bracts on the peduncles. 



1. P. acuminata, syn. Scalea ja- 

 ceoldes. 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. chrysdntha, syn. aristata, is 

 an allied species in which the invo- 

 lucral bracts are terminated by a 

 fine bristle. 



P. grdcilis is a more delicate 

 plant with purple, lilac, or white 

 florets. 



31. HELICHBtSUM. 

 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. Hei'ichrysum bracteatnm. 

 and are tall leafy plants with soli- 

 tary large flower-heads, in which the involucral bracts are 

 spreading or recurved, or clustered and small with incurved bracts.
