GERANIUM. 149 



Tricolor Arboreuin, or Three-coloured Tree Geranium, is 

 similar, both in the form of the leaves and the flowers, to 

 the Hearts-ease : the flowers are white and red, and un- 

 commonly beautiful. In appearance, it is neither more nor 

 less than a large red and white Hearts-ease. The Oval- 

 leaved Three-coloured Geranium bears a flower somewhat 

 smaller, but of the same form and colour. The Birch- 

 leaved, in all its varieties, is remarkably handsome, with 

 brilliant red flowers. The Wrinkly-leaved has very large 

 and beautiful blossoms: the Sea-green-leaved is an ex- 

 ceedingly elegant and delicate plant : the Heart-leaved 

 particularly luxuriant. 



Mr. Andrews observes, that the varieties of the Ge- 

 ranium Citriodorum, or Citron-scented Geranium, are the 

 only ones which make a powerful appeal to the olfactory 

 nerves, without rubbing the leaves. Most of them emit an 

 agreeable odour when lightly rubbed with the finger; and 

 a person approaching a Geranium, almost mechanically 

 rubs or plucks a leaf for its perfume; or, with some species, 

 for its soft velvety surface : 



" And genteel Geranium 

 With a leaf for all that come," 



seldom fails of obtaining notice and admiration, however it 

 may be surrounded by the most curious or brilliant exotics. 

 The Thick-stemmed Geranium is a very singular plant. 

 " This species,"" says Mr. Andrews, " was found (by Mr. 

 Antoni Pantaleo Hove, in 1785, while Botanical Collector 

 to his Majesty) near five feet high, in the bay of Angra 

 Peguena, on the south-western coast of Africa, in the 

 chasms of a white marble rock, apparently without any 

 earth; for, on pulling up the plant, the roots were several 

 yards in length, naked, and as hard as wire ; and appeared 

 to have received nourishment solely from the moisture
