Inuleae. Capitula heterogamous or homogamous, corolla in tubular 

 florets has a limb with four or five teeth. Usually yellow in 

 colour. Anthers tailed at the base. Pappus usually setose with 

 simple or plumose bristles. Bhimea, Filago, Antemiaria, Gna- 

 phalium, Helichrysum, Leontopodium, Tarchonanthus, Raoulia, 

 Odontospermum and Pulicaria. 



The plants are very varied in form. They generally have alternate 

 leaves, often with woolly hairs; others are heath-like. The species 

 are very widely distributed. Several of these genera include well- 

 known plants. Leontopodium alpinum is the Edelweiss, Odonto- 

 spermum pygmaeum is a " Rose of Jericho ", a small shrubby plant 

 in which the involucral bracts close up over the flowers in dry 

 weather and open out again when damp thus allowing the ripe 

 fruits to escape at a time most suitable for germination. Heli- 

 chrysum (Fig. 1882) is a large genus of some 400 species, found

chiefly in South Africa and commonly grown in gardens under 

 the name of Everlastings, on account of the stiff, papery nature of 

 the florets. Some are brightly coloured. The genus Raoulia 

 contains some twenty New Zealand species which are woolly 

 herbs growing in dense mats or white cushion-like masses, some- 

 times referred to as Vegetable Sheep.
