THE PITCHER-PLANT FAMILY. 40 1 



mode of propagation. Still it is interesting to know that this 

 method is practicable.* 



Some of the species naturally exhibit a tendency to vary : 

 thus JV. Hookerii is a form of N. Rafflesiana, having shorter, 

 rounder, and more highly-coloured pitchers ; and the red and 

 green pitchered varieties of N. rubra (Hort.) are natural sports or 

 seminal forms of N. khasyana, a plant often met with in gardens 

 under the name of N. distillatoria. The pitchers of these plants 

 are so variable even on the same individual plant, that no reliance 

 can be placed on them as marks of specific distinction. 



The following hybrid forms, raised by Messrs Veitch, are 

 in cultivation, our descriptions being abbreviated from the 

 ' Florist : ' 



N. Chelsonii. Stem downy; leaves, including the petiole, 

 1 6-1 8 inches long, 3-4 inches broad, glabrous; pitcher 3-4 

 inches long, 2^ inches broad, purple-spotted. This form is 

 a cross between N. Rafflesiana (Hookerii), which was the male 

 parent, and N. Dominii, the female parent, the latter being 

 itself a hybrid. The pitchers are somewhat like those of JV. 

 Rafflesiana, but broader, and with the mouth less prolonged at 

 the back. 



N. Sedenii. Stem glabrous; leaves 7 inches long, i^ inch 

 wide, coriaceous, glabrous ; pitcher (probably not fully de- 

 veloped) 3 inches long, i inch wide, oblong. This form is 

 stated to have been raised from the pollen of N. khasyana (distil- 

 latoria] applied to the female flower of an undetermined species. 



N. Dominii. Stem purplish, slightly downy ; leaves gla- 

 brous, elliptic-lanceolate, tapering at the base, and decurrent 

 along the sides of the petiole ; pitcher 6 inches long, 2 inches 

 wide, oblong, deeply winged, wings purple, spotted and fringed 

 at the margin; mouth infolded at the edge, furrowed, prolonged 

 at the back into a long tapering striated process about an inch 

 in length ; lid oblong, 2 inches long by i ^ inch wide, smaller 

 than the mouth of the pitcher, speckled with purple glandular 

 dots, ribbed at the back, and provided at the base with an ex- 

 current recurved process. This form is stated to have been 

 the result of the fertilisation of the female flowers of N. Raffles- 

 iana with the pollen of an undetermined species from Borneo. 



N. hybrida. Stem glabrous ; leaves oblong-acute, tapering 

 at the base into a short stalk, glabrous ; pitchers 5 inches long, 

 membranous, green, or with a few purple spots within. This 

 form, and the succeeding one, are stated to have originated
