1. ampullaria, Jack. Bright green, st. and Ivs. when 

 young rusty-hairy: pitchers small, green or with few- 

 purple spots; peristome broad, obliquely inclined 

 inward; lid small, reflexed. Malaya, Sumatra, Borneo, 

 New Guinea. B.M. 5109. I.H. 24:272. F.S. 22:2325. 

 An interesting type, easy of growth, and often pro- 

 ducing clusters of small pitchers. 



2. albo-marginata, Lobb. St. and Ivs. white-tomen- 

 tose when young: pitchers tubular, dull green with 

 abundant purple blotches or areolations; peristome 

 bounded below externally by a white collar. Malaya, 



Sumatra, Borneo. G.C. 1872:541, 

 542. F.S. 22:2343, 2344. Grows 

 in stiff moist clay in native home 

 (Burbidge), but difficult under cult. 

 A variety with deep purple pitch- 

 ers is grown as N. dlbocincta var. 

 rubra. 



3. cincta, Mast. (N. Northiana x 

 N. albo-marginata). Lvs. thick, 

 deeply amplexicaul, decurrent: 

 pitchers 3-10 x 1-3 in., dimorphic, 

 lower ventricose in inferior, cylin- 

 dric in superior half, upper cylindric 

 to funnel-shaped, green flushed with 

 red and richly purple-blotched; per- 

 istome bounded below by brownish 

 white felted collar. G.C. II. 21: 

 576. R.B. 21, pp. 268, 269. Gn. 

 W. 4:101. A vigorous and strik- 

 ing natural hybrid got from seeds 

 collected by Burke. In all charac- 

 ters nearly intermediate between 

 parents. 



4. Northiana, Hook, f . (N. spuria, 

 Beck). Robust, bright green: Ivs. 

 amplexicaul, deeply decurrent, ses- 

 sile, thick herbaceous, apex peltate: 

 pitchers 3-14x1-4 in., dimorphic; 

 lower sub-ovate, pale green with 

 purple spots, upper funnel-shaped 

 with recurved base, richly purple- 

 spotted; peristome widely expanded. 

 Borneo. G.C. II. 16:717. Gn. 23: 

 492 (asN. Morganiae). J.H.S. 21: 

 236. Gn.W.4:105. J.H.III.44:127. 

 Difficult of growth but with lovely 

 large pitchers. It has been used as 

 parent for some fine hybrids. 



5. mixta, Mast. (N. Northiana x 

 N. maxima). Lvs. amplexicaul, 

 deeply decurrent, petiolate, elliptic 

 with peltate apex: pitchers 3-12 x 

 1M-3H in., ventricose - cylindric, 

 yellow-green and sparsely purple- 

 spotted below, abundantly flecked 

 with large spots above; wings nar- 

 row, or absent below, expanded and 

 fringed higher; peristome rich pur- 

 ple. G.C. III. 13:47. G.Z. 20:145. 



G.M. 36:754. F.E. 16:447. G.W. 10:527; 14:293 

 One of Tivey's best hybrids that makes a strong 

 growth, flowers readily, and has been a parent for some 

 even finer hybrids. 



6. sanguinea, Lindl. Lvs. sessile, deeply amplexicaul, 

 thick, herbaceous, oblong-lanceolate : pitchers 3-10 x 

 2-3 in., ventricose-cylindric to cylindric, bright red 

 to reddish green, wings expanded fringed, or narrow 

 plain; peristome laterally expanded. G.C. 1849:580; 

 1872:541. F.S. 22:2343. F.M. 1874:128. Gn.W. 24: 



2463. Three old-time 



nepenthes. 

 Much confused in 

 collections and diffi- 

 cult to distinguish: N. 

 phyllamphora above, 

 JV. khasiana in the 

 middle, N. distil- 

 latoria below.
