Nos. 28 to 45. Flask-shaped and Spotted Pitcher 

 Plants, a key to which will be found ou page 1073. 



1. bicalcar&ta. Hook. Young pitchers bowl-shaped, 

 33^x3 in.: old pitchers 8x6 in., including a neck 2 in, 

 long: color of pitchers less vivid than in N. sanguinea. 

 Borneo. I. H. 28:408. G.C. II. 13:201. Gn. 17:237; 33, 

 p. 29. — The .spurs resemble 

 the fangs of a snake. Appa- 

 rently no other species h.'is 

 such spurs. G. W. Oliver 

 writes that all the specimens 

 he has seen have been yellow- 

 ish green, covered with rust- 

 colored, downy material. 



1470. How the pitchers 

 change their shape. 

 The eiiilii'st .111(1 best are 

 mug-sh;iped ones; the topmost 

 pitchers of old and tall plants 

 are cylindrical. N. Rafflesiana, 

 both from same plant. Adapted 

 from B. M. 4285. 



1471. Three old-time 

 Nepenthes, 



Much confused in collec- 

 tions and difficult to dis- 

 tinguish : N. Phyllam- 

 phora above, N. Kha&iana 

 in the middle, JV. distil- 

 latoria below. 



2. Madagascari^nsis, Poir, Lvs. leathery, reddish 

 beneath, 5 x U-4 in. : pitcher 4-6 in. long, crimson, flask- 

 shaped; mouth nearly circular, with scarcely any neck. 

 G.C. II. 10:685. 



3. sanguinea, Lindl. Pitcher 12x2 in., quite cylin- 

 drical; no neck. Malaya. F. 8.22:2343. G.C. 1872:541 ; 

 II. 11:13. P.M. 1874:128. -This is one of the very few 

 species that has a sessile leaf. 



4. Mastersiana, Veiteh (N. sanguinea x N. Khasi- 

 dna). Pitcher 7x2 in., cylindrical, but the upper third 

 narrower, deep claret red, sometimes with spots of darker 

 red. G.C. II. 16:749; 21:249. I.H. 33:618. Gn. 23:390. 

 Gng. 4:183. — This superb hj-brid has the sessile leaf and 

 red pitcher of JV. sanguinea, with a form of pitcher in- 

 termediate between its two parents. There is a dark 

 colored variety and a lighter colored one. 



5. Kennedyana, F. Muell. Pitcher 5 x IK in., reddish, 

 cylindrical, but narrower above ; lid as large as the mouth 

 and nearly horizontal. Australia. G.C. II. 17:257.
