Nepenthes L. 



The material of Nepenthes secured by thc collectors of the Dutch New Guinea expéditions 

 consists of four gatherings and represents three species, of which one is new to science.

Dutch New Guinea at the Noord-river near Van Weelskamp: Sagomarsh. : G. M. Versteeg n.

 the Noord-river on the first hill near Sabang-camp : G. M. Versteeg n. 1229 ti. and fr. 14 Juni 1907. 



The four sheets consists of basai shoots that hâve grovvn along the ground and hâve 

 produced clusters of pitchered leaves (v. Pflanzenreich 1. c. 13) with an occasional largcr 

 leaf characteristic of the species. Thèse bear no flowers. The note is added (translated) : 

 »Pitchers equally green, tendril somewhat red". The leaves are mostly of oblanceolate shape, 

 as in var. microsepala described below, but uhether they are referable to that var. it would bc 

 impossible to détermine in the absence of the blooms. 



A similar sheet to the above is n. 1047, that is notcd as being an epiphyte. Such a 

 growth-relation is not infrequently assumed by species of Nepenthes that ordinarily grow on 

 the ground. 



A set of five sheets (n. 1229) is of spécial interest. It includes shoots with pitchered 

 leaves, also staminate pistillatc and fruiting inflorescences. While they show thc gênerai 

 characters of the species, the leaves are most oblanceolate. But the flowers show marked 

 variation. While thèse evidently approach to Beccari's var. longicarpa, their most striking 

 peculiarity is the uniform small size of the sepals, that givcs to the inflorescence a loose 

 open aspect, instead of a dense aggregate one as in the type.
