Aquatic & semi-aquatic plants of Borneo

[kuching]

Hi all,

I would like to share some of my pictures taken in the jungle streams & rivers of my homeland - Borneo.



First, I want to show you the semi-aquatic aroid of Borneo. This one below is Aridarum caulescens var. angustifolium:













Aridarum nicolsonii

Bucephalandra motleyana from the hill streams of lowland forest.












The habitat of semi aquatic aroids:

Bucephalandra motleyana from the mountain streams of highland forest. (above 3,000 feet from sea level)














Piptospatha sp.

Some pictures taken at a river near Sarawak-Kalimantan border, 2 months ago:







Got a few clump of hairgrasses in the river:

Hygrophila also growing here:





Got freshwater pipefish & pufferfish hiding here:









I think this one is Barclaya kunstleri...found it in a stream next to that big river:

Found Bucephalandra motleyana in a waterfall near the border....the margin of the leaf is undulated!

thanks for sharing...

Thanks Adrian. More pix to post soon....

Finally found Aridarum borneense...which is endemic to some mountain streams of western Sarawak. Do you notice that the leaf arrangement is just like a fan?







The rotten flower (going to bear the fruits):




The habitat: waterfall

This creeper is another type of aroid growing by the stream, Rhaphidophora beccarii:






Semi aquatic fern,Trichomanes javanicum:








The habitat of semi aquatic aroids & ferns:

Next location is another paradise on earth....that place got a lot of waterfalls & cascades.....it's the home for Aridarum nicolsonii:





Aridarum nicolsonii, also endemic to western Sarawak:

[kuching]

I was shocked to find something interesting growing together with Aridarum nicolsonii....it is a species of Homalomena. Later, I was told by a researcher (aroid expert) that it is a new species!!!


Homalomena sp. It is related to H. paucinerivia in other mountain streams.












This is another species of Homalomena....this type is not semi aquatic aroid even it is growing near a stream. Take note the shape of leaf is different from those semi aquatic aroids which got streamlined leaves, growing very closed to the stream. This one is newly described species called Homalomena velutipedunculata :

[kuching]

Sometimes in the upper part of fast flowing forest stream is almost flat & water is flowing slow there. In this habitat, I found Barclaya kunstleri. Unlike it's related species Barclaya motleyi (mostly found in the swamp), this Barclaya is growing in higer altitude or near the head water....

I was so excited to find this new semi aquatic aroid called Hottarum sarikeense for the first time in the jungle stream of central Sarawak. (November trip)

[kuching]

Some of the Piptospatha grabowskii in central Sarawak got variegated leaves:




Submerged in the water:





Grow together with Cryptocoryne bullosa (left):
