Mathew Jebb, director of the Christensen Research Institute in Madang,
PNG, prepared a treatment/revision of the genus in New Guinea and
surrounding islands . I do not recall, off hand, the publication
details, but I remember it had descriptions of each species, botanical
keys and line drawings.
I am not sure if he is still working on the genus.
Mathew's main interest was on mutually beneficial associations between
plants and insects, rather than the one-sided affair of Nepenthes,
Drosera, etc. He was working on the ant-plant genera of the Rubiaceae,
Myrmecodia, Hydnophytum and new genus (whose name escapes me for the
moment) that he described, and the structure and function their swollen
and excavated homes for ants. Althogher more sensitive and new-age
than rapacious carnivourous plants :-)
