Trying to justify back-dating this posting; this jpeg composite was created way back in mid-Jan 2008.

The commonly traded species has been identified as H. moseleyanum (syn. H. papuanum) and is also almost identical to the species from a Botanical Gardens in Europe collected in 1960s or 1970s from New Guinea. They have matt lime-green semi-succulent leaves and silvery brown tubers. The species from Northern Australia is also similar but is more deciduous under the same cultivation regime. It shreds leaves easily when dry. Finally, 2 species from Irian Jaya looks more intermediate just like the other H. aff. moseleyanum from the Philippines and Bogor, Java. These 2 irian plants differs in having longer pointed leaves.
Maybe it is more practical to define this group as a formicarum-moseleyanum complex rather than to pin a name to it.

The above species comes from the Philippines. Like the former Bogor plant, it has semi-succulent leaves stacked closely together and the veins are not prominent.

This one comes from Bogor, Java. However, i'm hesitant to say that it is from Java because it actually comes from Bogor Botanical Gardens. What's the chances of picking up dropped clump of hydnophytum seedlings during a garden stroll? This is probably the most interesting species amongst hydnophytum with great horticultural potential. The leaves are relatively small, shiny and a bit succulent. The branches are short and would form branchlets. The caudex is also very smooth, silvery green and shiny. And for the best part, the caudex grows faster compared to say H. formicarum and even H. moseleyanum. It is relatively tolerant of low humidity and burst into caudex growth when it is given generous watering. Well it definitely has more affinities to H. moseleyanum.

Continuing from Part 1, this species comes from the island of Borneo. It is really similar to H. formicarum in Part 1, except for the generally smaller stature and having linear leaves. It is definitely a slower plant compared to H. formicarum type and it has to start off life with a smaller seed too.

The flowering plant above is only 3 mths old from seed! Perhaps its rapid growth is an adaption to the strongly seasonal climate with a short rainy monsoon. The caudice is not obvious at this stage. But it is clear from the photo below that the stem will abscise just above the tiny bud:
