Hi Lino,
that's great that You have got these interesting Bucephalandras until now rather seen on Japanese sites
"New species": provided that they all really belong to the genus
Bucephalandra, it's most likely that they are all local forms of the one highly variable species
Bucephalandra motleyana, and don't belong to different species.
Also "our" reddish-brown plant here:
pflanzen/Bucephalandra-motleyana-358.html is not
the B. motleyana itself but only a particular local form of this species among many other forms. It had been collected by W.A. Tomey in Kalimantan Barat (Borneo) who found also a green B. motleyana form.
There's a paper from Bogner and Hay (2000) about Bucephalandra and related genera:
http://www.rbgsyd.nsw.gov.au/__data/ass ... Bog179.pdfThey accept only 2
Bucephalandra species:
B. motleyana and the bigger
B. gigantea (not cultivated). They list quite a number of species names as synonyms of B. motleyana. E.g.
Bucephalandra catherineae is a plant with very narrow leaves, perhaps similar to Your "North Sanggaua", but as there are transitional forms, the authors count it among
B. motleyana.
A very similar species is
Aridarum caulescens, differing from B. motleyana mainly by flower characters.
only kedagang is in my tank for about a month. The plant emits about one leaf every week.
That's stunningly fast!
