Cult. All the species of this genus are worth cultivating on 

 account of their leaves, which fall at the slightest touch, as those 

 of the sensitive plants. They grow best in a mixture of loam, 

 peat, and sand, and may be propagated by young cuttings planted 

 in sand, with a bell-glass placed over them in heat, or they may 

 be increased by separating the tubers of the roots.

 Native of North America, on the Canadian river. Flowers 

 white. 



Intermediate Darlingtonia. PI. 1 foot. 



Cult. Peat and sand, mixed with some vegetable mould is 

 the best soil for the species of Darlingtonia. They should be 

 grown in pots, and placed among the Alpine plants, and they 

 may be increased by dividing at the root, or by young cuttings 

 planted in sand, with a bell-glass placed over them. 



CCXXIX. DESMA'NTHUS (from St^r,, desme, a bundle, 

 and ai'Sur, anthus, a flower ; in reference to the flowers, which 

 are collected into bundles or spikes). Willd. spec. 4. p. 1044.

 the filaments in the lower flowers of the spike sterile, membra- 

 nous, and dilated or filiform. Legume dry, continuous, 2-valved. 

 Herbs or shrubs, with bipinnate leaves, and linear leaflets. 

 Spikes of flowers axillary, pedunculate, ovate or cylindrical. 

 Flowers white, but with the fertile filaments usually yellow. 

 Perhaps it would have been better to have divided the present 

 genus into three separate genera instead of sections.
