Arums and little clusters
The arum family was on the agenda today. We went by fully air-conditioned speedboat from Sibu in the direction of Kapit. After a three hour journey, we landed and hired a small wooden boat to take us further into the jungle. However, due to the low water level, we had to cancel the boat journey early on and continue on foot. The habitat was a fast-flowing stream, about 20 metres wide, with some small waterfalls.
The bank area is covered with many plants from the arum family and ferns. The most abundant plant on the bank is probably Ooia grabowskii, which had slightly more intense blossom here than at the other locations. Aridarum paulescens, with its white flowers and considerably narrower leaves, is also encountered relatively frequently. The extremely small-leaved Bucephalandra pygmaea 'Kapit' is encountered in only a few places. The little clusters grow at a distance of a few hundred metres apart. Piptospatha spec., which is easily confused with Bucephalandra motleyana, is often encountered in close association with Bucephalandra pygmaea 'Kapit'. This means this plant is presumably suitable for aquatics.
The cream coloured pseudo-leaves, which are beautifully red patterned, are especially attractive. Another genus belonging to this family which dominates here is Homalomena spec., which grows to a height of approx. 40 cm and is likely to be under water even longer in the rainy season. To round off our trip, Stefan discovered Microsorum pteropus 'Trident' on a clayey rock face. This plant is well-known in aquatics as a Java fern rarity and has a particularly delicate leaf structure.
