Many of these species are most remarkable in structure 

 and appearance, and in these days of quick transit it is to 

 be hoped that some enterprising traveller may succeed in 

 sending them home safely to enrich our collections. That 

 they would receive a hearty welcome is beyond question. 



A good deal has been accomplished by hybridising species 

 of Nepenthes, but much more remains to be done. The 

 great difficulty is in getting both sexes of the desired species 

 in flower at the same time. As a general rule, the habit 

 and form of the male parent predominate in the hybrid. 

 N. Fiafflesiana, N. distillatoria, and N. Phyllamphora have 

 been frequently used in the production of hybrids, with the 

 result that the offspring are too much alike. 



As an example of real improvement effected by hybridising, 

 N. Mastersiana may be cited. The female parent of this 

 hybrid was the rather scarce N. sanguinca, the male being 

 N. khasiana, a vigorous growing species. The resultant 

 hybrid is a plant rivalling in beauty of form and colour any 

 species in cultivation, with the additional recommendation 

 that it is not excelled by any in vigour of constitution or 

 iu freedom of growth. 



Another distinct hybrid is iV. Dichsoniana, raised in the 

 Edinburgh Botanic Garden in 1884 (see Plate I.) The 

 female parent, N. Bafflesiana, was fertilised by pollen of 

 N. Veitchii, supplied by Messrs Veitch from a plant in 

 their nurseries at Chelsea. The result is a hybrid having 

 the form and habit of N. Veitehii, with the vigour of
