340 J. U. MACFARLANE. NEPENÏHACEAE. 



The following characters distinguish it: 



Nepenthes ampullaria Jack var. microsepala Macfarlane. 



Folia fere sessilia, elliptica ad oblanceolata. Inflor. laxa, cymae 7 — 4 floii (in typ. 5 — 2). 

 Sepala in fl. cf. 3.5 — 4 mm. longa elliptica ad ovalia (in typ. 5 — 6 mm. late ovata ad ovato- 

 oblonga), circum basi staminum columnae sparce pubescentia. Sepala in fl. Q. 3 — 3.5 mm. ovata. 



The existence of the above variety, and also of Beccari's var. longicarpa and Gcelvinkiana 

 [Malesia III, 1 886/8 J along the southwestern part of New Guinea strongly suggests that the 

 species, while widely distributed from the Malay Peninsula southward through Bornéo and 

 Sumatra, and reniaining very constant according to présent knowledge over that area, is 

 undergoing changes of a mutational kind in New Guinea.

This species is represented by two sheets of spécimens, ail young and oflowgrowth.lt 

 has already been reported from the Island by Beccari, who collected it at Ramoi near Sorong and 

 at Wandamen in Geelvink Bay. The species shows considérable variations over its entire area 

 of distribution (MACFARLANE 1. c. p. 65), and is closely related to N. Kennedyana, N. albo-lineata, 

 and allied species of N. E. Australia, ail of which hâve evidently become geographically 

 isolated from the présent most widely extended species of the genus.
