The Ixia cinnamoinea gives out its frajrranco in the 
evening only; the highly-scented Lesser Orpine [Cra^' 
sulu odoralissinta) only in the night; the Epldendrum 
frayrans, morning and evening ; another species of 
Epideudrum, hung up in a room, ■without earth or 
"VN'ater, yields an agreeable perfume for j-ears. The 
flowers of the Hebeiistreitia dentata are scentless in the 
morning, have a disagreeable smell at noon, and give 
out in the evening a fragrant odour, not unlike that of 
the Hyacinth. 
These properties of flovrers, and the opening and 
shutting of many at particular times of the day, led to 
the idea of planting them in such a manner as to indi- 
cate the succession of the hours, and to make them 
supply the place of a watch or clock. Those who are 
disposed to try the experiment may easily compose sucli 
a dial by consulting the following table, comprehending 
the hours between three in the morning and eight ia 
the evening.
