any time in summer, in pots plunged in the bark-bed, where they 

 then take root, and arc ready to pol off singly in the autumn season. 



The Sensitive and Humble sorts often branch out profusely, so as 

 to furnish plenty of young shoots for cuttings, which should be 

 planted in pots in the summer season, plunging them in the bark- 

 bed, where they often readily lake root, and form good plants. 



These modes should, however, only be practised when seed can- 

 not be procured. 



The general culture of all the species is afterwards to keep them 

 always in pots placed in the stove, being plunged occasionally in the 

 bark-bed, especially the Spreading Sensitive kinds, frequent waterings 

 being given in summer and winter, but considerably the most in the 

 summer season: shifting them into larger pots as they increase in 

 growth. And although most of the sorts will live in the open air 

 in the heat of summer, it is the best practice to expose them but 

 sparingly. 



The fourth and fifth sorts are held in high estimation on account 

 of the singular sensibility lodged in their leaves; which, in conse- 

 quence of being touched or shaken, either by the hand, a stick, or 

 the least wind blowing upon them, the wings of the leaves suddenly 

 close, and the foot-stalks fall down. 



The periods of lime which the leaves, Sec. require to recover 

 themselves, after falling from any irritation, are according to the 

 vigour of the plant, the hour of the day, the sereneness of the atmos- 

 phere, and the temperature of the heat of the stove, &c. being often 

 from ten or fifteen minutes to an hour or more. .< 



The plants also every evening naturally contract themselves, and 

 expand again in the morning. They are all ornamental and curious.
