Cryptocoryne bullosa Engler

Cryptocoryne bullosa is described a long time ago by Engler (Engler, 1879). Long time it remained a secret if this plant would be found again. Due to the efforts of Henry Kee Ong from Kuching (Sarawak) and Yeok Ong (Singapore) in the 70s, we know a lot about this plant. But it is not an easy to grow plant.

In December 1999, Yuji Sasaki collected C. bullosa in the Sungai Sibiak (the same location as Jacobsen 78-3 and Bogner 1357). No infloresenses were found.

See the full picture (de Wit 1990) for the opened spathes. These spathes were collected around 1970 by Henry Ong.

The distribution of C. bullosa in Sarawak is restricted to a small area.
       

Cryptocoryne bullosa is a rare plant. Though it is occasionally collected, I do not know of any success in cultivating this plant. A couple of reports actually are on C. affinis. The form of the leaves of these plants from Kelantan (W. Malaysia) are rather close to C. bullosa (Sadilek 1968, van der Vlugt 1969, 1970). Some import firms and retailers like to sell their (common) plants as a novelty! The more recent imported C. keei and C. hudoroi are much more easy to cultivate. But these are also very difficult to flower, so you probably never will know what you are cultivating. C. bullosa has a (dark) green upper side of the leaves without (in cultivation) brown spots.  See for the differences in the leaves the pages on C. keei and C. hudoroi for more details.
The spathe of C. bullosa is very short, ca 4 cm, with a red limb and a very dark collar.
