Cryptocoryne bangkaensis Bastmeijer |
| (Document service) |
Cryptocoryne bangkaensis is known from Sumatra: the South Sumatra province and
the islands Bangka and Belitung. On Bangka it grows on some places together with C. longicauda Engler. From Belitung also C. fusca De Wit is known. The South Sumatra province
is hardly investigated in respect for Cryptocoryne- if still possible.
C. bangkaensis is characterized by its limb with a more or less bumped surface
with only protuberances on the margin of the limb, a narrow throat and a pronounced collar.
The limb is mostly recurved and not fully flattened and is finely dotted. There is a some
variation in the colour of the limb.

C. bangkaensis is only in 2007 recognized as a new species and was up to that
time regarded as C. scurrilis De Wit (1962, 1990).
Thanks to the collections of Waser (CH) and Sasaki (JP), who made an exhaustive search on
the islands, the species was much better understood and it was clear that the spathe
did not match figure 3 in the plate from de Wit's description. Read the article by
Bastmeijer & Jacobsen (2007) in the Document
service.
C.bangkaensis is not easy to grow in a normal aquarium. It grows well in an
more or less acid soil of for example beech tree litter.
