Leucogenes. | COMPOSITAE. | 979 
A beautiful little genus of 2 or 3 species confined to New Zealand. In habit it 
much resembles the Eurpoean and Asiatic Leontopodium, a montane genus that contains 
the well-known Swiss edelweiss, but which differs altogether in the structure of the 
flower-heads. The species of Leucogenes have been carefully studied by Beauverd, who 
points out that they are more closely allied to the section Psychrophyton of Raoulia than 
to any other group.

A beautiful little plant, with precisely the aspect of the edelweiss of the European 
Alps (Leontopodium alpinum), but with flower-heads of different structure.

2. L. grandiceps Beauverd in Bull. Soc. Bot. Genéve, 1 (1910) 241.— 
Densely tufted. Stems much branched, decumbent and woody at the 
base, 2-8 in. high ; branches ascending or erect. Leaves densely imbricate, 
spreading or recurved, +-4 in. long, oblong- or obovate-spathulate, obtuse, 
flat or concave, clothed on both surfaces with appressed silvery tomentum. 
Peduncles composed of the elongated tips of the branches, leafy throughout, 
but the leaves usually not so closely imbricate. Heads congested into a 
terminal bracteate glomerule surrounded by leafy bracts, as in L. Leonto- 
podium, but bracts rather shorter and broader. Involucral bracts in 2 
series, linear, tomentose on the back, with brown scarious tips. Florets 
numerous; females few, in 1 series. Achene silky. Pappus-hairs few. 
rather stout, thickened above.—Helichrysum grandiceps Hook. f. Handb.
