SELECTION OF PLANTS. 53 



159. ERICA CILIARIS, or Ciliated Heath. 



This plant will bear the open air in mild weather, 

 though it will be prudent to keep some in the greenhouse 

 through the winter, as our climate is so variable. It blows 

 from July to September, and thrives best in bog-earth. 



It is propagated by cuttings, is a native of the Cape, 

 and was first brought to England in 1773. 



It belongs to the 8th Class, under the head " Octan- 

 dria Monogynia." 



160. CROTALARIA TRIFLORA, or Three-leaved 

 Crotalaria. 



This is a greenhouse plant, which blows in June and 

 July, is increased from seed, and the best way to secure it 

 is either by putting the plant in the greenhouse w r hen it 

 is in bloom, or by guarding it by a small glass hung on a 

 stick. 



This is a native of the Cape, and first brought to Eng- 

 land in 1786. 



It belongs to the 1 7th Class, under the head " Diadel- 

 phia Decandria." 



161. VERBENA TRIPHYLLA, or Three-leaved Vervain. 



This is properly a greenhouse plant, but will live through 

 a mild winter in the open ground, provided it is not ex- 

 posed to the north-east winds. When it is not in the 

 greenhouse it often loses its leaves in the winter, but others 

 will appear in the spring. It blows in July with a white 

 blossom, and the leaves smell like the lemon, which is the 

 reason that many people call it the lemon plant. It is 

 increased by seed or cuttings.
