The Dragon’s-blood Tree is a plant that every one speaks of, 
which most have seen, if not the gigantic inhabitants of the 
Canaries, yet in our gardens at home; for there is scarcely a 
Botanic Garden in Europe which does not possess a plant of 
greater or less size ; but a flowering plant 1s of very rare occur- 
rence, save in tropical or subtropical regions. Our friend Dr. 
Mackay has had the good fortune to bring the plant to flower in 
APRIL Ist, 1851.
