Cryptocoryne hudoroi Bogner & N. Jacobsen |
| (Document service) |
In the 80s of the last century, two Cryptocoryne plants from Borneo were
collected which closely matched the very rare C. bullosa. It was very
interesting, for it means that the area for the plant was greatly widened. The same
enlarging of the area was found for other Cryptocoryne, for example for C.
longicauda: it fits the picture. So it was a great surprise to find that the
chromosome number for the two 'new' plants turned out to be 2n = 20, only known hitherto
for C. striolata (Arends et al. 1982). The inflorescence of both 'new' plants
were not known, so a big challenge to find out. In short, both plants turned out to be a
new species, C. keei from West of Kuching (Sarawak) and C. hudoroi from
North of Banjarmasin (Indonesia).

This is a submersed cultivated Cryptocoryne
hudoroi. They grow very well in a normal aquarium.

Note the only two leaves of this plant. Though
it proved extremely difficult to flower it, you don't need such big plants.

The limb of the spathe of C. hudoroi is
very long and more or less twisted. In contrast to the picture left, the tube is strongly
twisted.

C. usteriana from the Philippines can
have the same size of C. hudoroi. The inflorescence is quite different.

Cryptocoryne hudoroi is an easy to grow plant for the aquarium. It is imported
rather often, so the chance to find this one is rather big. The leaves can become rather
tall, the blade up to 25 cm, in contrast to C. bullosa and C. keei which do not reach the half of this
size. Another plant, C. usteriana from the
Philippines has about the same size, form and structure. The latter mostly has a more red
lower side of the leaves.
