 of Phagnalon riqjestre, DC, used in Spain. 



No. 326. Tuft of plant of Raoulia eximia, Hook. f. 

 It grows in large tufts on the mountains of New Zealand 

 and is known as the Sheep Plant from its resemblance, 

 even at a short distance, to that animal. B. mammillaris^ 

 Hook, f., is called the New Zealand Pincushion, and 

 tufts of it are often used by the shepherds' wives for the 

 purpose that its name implies. 



Some fine tufts of these plants are exhibited in a special 

 Case opposite Case 49. 



On the middle shelf are dried leaves of Helichrysum 

 serpyllifolium, Less., known as Hottentot's Tea, and 

 H. nudifolmm, Less., called Kaffir Tea, both from the 

 Cape of Good Hope. 



No. 327. Plant of Cape Everlasting {Helichrysum 

 vestitum^ Less.). The white silvery flower-heads are 

 imported into this country in large quantities for decora- 

 tive purposes. Observe Chaplet, or Immortelle, made of 

 the flowers of the "Yellow Everlasting" {Helichrysum 

 orientale^ Gaert.), commonly hung about tombs on the 

 Continent. Other Everlasting Flowers used for decoration 

 exhibited in this Case are H. hracteatum^ Willd., Helip- 

 terum Mcmglesii^ F. MuelL, &c. 



On a lower shelf observe root of Elecampane {Inula 

 Helenium^ L.), used in medicine as well as in the French 

 liqueur Absinthe. 



No. 328. Plant of a Guayulb {Partheniuyn argenta^ 

 turn, A. Gray), from Mexico. This plant has recently 

 come into notice as a source of rubber. There seems, 

 little doubt that it will yield rubber of fair quality, but it 

 remains to be seen whether its extraction upon a com- 

 mercial scale will prove successful.
