EXOTIC FLOWERS AND PLANTS. 197 



A late writer in the periodical publications of 

 the Societe d' Agronomic of France reports, that 

 he strikes cuttings of stove plants, which have 

 very small or no visible buds, much more easily 

 in phials of water sunk in the bark-bed than in 

 mould. In this way he readily succeeds with 

 Oleander, Portlandia, and Blakea. 



These are the ordinary methods of propagat- 

 ing both hot-house and green-house plants by 

 seeds and cuttings that are of a woody nature, as 

 well as suffruticose ; i. e. half shrubby sorts. 

 Many are increased by suckers which rise from 

 their roots, or by offsets which proceed from the 

 collet of their stems. All the succulent tribe, 

 as Aloes, Messembryanthemums, Cactus, &c. are 

 propagated by offsets or portions of their stems. 

 Some few grow from leaves, as Bryophyllum, 

 Xylophylla; others by a leaf and bud only, as 

 Hoya, &c. Tuberous or fibrous-rooted plants 

 which are herbaceous, are increased by parting 

 the roots ; and bulbs which do not readily pro- 

 duce offsets may be made to do so by cutting off
