View on the Kahang river in Johore. The dark patches in the
water are pure stands of C. nurii
coll. B802 |
|
 |
It is easy to walk in the river bed during the dry season
(end of May) and collect some plants.

The c ollected plants are almost black, 25 cm (10") long
and have narrow ovate leaves with an undulated margin. No inflorescences were found.

In emersed cultivation, this plant is much smaller and also
the spathe has a short tube. See for details of the limb below.

The leaves are brownish and wider compared to these from the
Kahang river.

Before the limb opens, the spathe shows the typical formed
bud.

Only a few C. nurii were flowering in the stream.
Note the rough surface of the limb.The width of the limb is c. 2.5 cm (1").

Jacobsen collected C. nurii near Mersing in the
state of Johore. This is a very typical picture of the spathe of C. nurii.

This C. nurii is collected by Jacobsen in the south
of the Pahang state. The plants were up to 40 cm (16") long.

This plant with a yellow limb of the spathe and the pallid
nerves on the leaf, is found by Peter Boyce in the Taman Negara F.R.(Pahang).

A wide stream near Mersing (Johore) with C.
nurii growing submersed. The leaves often have pallid veins and transverse markings.
Sometimes they show some red dots.

A emersed cultivated C. nurii. The
plant is very tiny, as is the spathe. Compared to C. minima, the limb has a
pronounced cordate base, stands more or less horizontal and has a small tail.

In emersed culture, the leaves may show a
different colored venation. This plant was very weak and did not survive for a long time.

Opened kettle of C. nurii. It is a bit
abnormal in showing some male flowers halfway the spadix. This is occasionally seen in
many species. The number of the male flowers is rather low.

Van Wijngaarden discovered a somewhat deviating
form of C. nurii in an import shipment. Note typical bud of the inflorescence.

The leaves are brownish marmorated. The limb of
the spathe shows the typical structure with the irregular protuberances.

The same plant seen from the front. Although the
limb of the spathe is less cordate, it must be regarded as C. nurii.

which showed a yellow limb of the spathe

The opened kettle is probably of a submersed grown spathe (rather long). Note the surface
of the limb.

Distribution of C. nurii in West
Malaysia. In the south are the 'classical' localities in the state Johore. The other are
found in the state of Pahang.

Cryptocoryne nurii grows in West Malaysia in Johore and in Pahang on several
places. It is often collected and is exported in thousands. However, this plant is
extremely difficult to cultivate over a long time.
Furtado (1935) describes a plant with leaves up to 35 cm and a spathe with a tube up to 12
cm. As special feature he mentions a peduncle of the spathe of about 10 cm. Apparently he
described a submersed grown plant. In emersed culture, all parts are much smaller, the
spathe not exceeding 5 cm.
Imported non flowering plants of C. nurii can sometimes be recognized by some red
spots, mainly on the main nerve of the blade. Rataj & Horemann (1977) give a nice
picture of this mark. But this feature is not always present. C. nurii shows some
variation both in the spathe and in the leaves. More collections are wanted, especially
from the central and northern parts of W. Malaysia. The C. sp. ('serrulated leaves') is probably also a form of to C. nurii.
