Cryptocoryne zukalii

Cryptocoryne zukalii spathe

Cryptocoryne zukalii is one of the rarest cryptocoryne in the hobby. It is one of the crypts whose original collection locality is not know. This plant which I have in culture has a unique history. C zukalii was first collected and exported in the 70’s. Jan Bastmeijer got this plant from Robert A Gasser(Quality Plants, Florida, USA) around 1975. I got this plant from Ghazanfar Ghori last year who had got this plant directly from Jan.

C zukalii spathe typically has a long limb of  spathe which is almost perpendicular to the tube. This spathe was almost at a right angle to the tube. The limb was more or less smooth with pumpkin yellow color. The throat ends in a sharp border.

I have been growing C zukalii in a mixture Aquasoil Amazonia I, laterite and leaf mould in my freshwater set-up. Once I have a couple of extra runners I am planning to add one to my blackwater setup and see how it does.

Nacogdoches, Texas- Wetland Habitat Study Trip

Posted in Collection Trips on December 6, 2009 by Bhushan Dalvi


Eleocharis parvula  

In the first week of November I got a chance to visit some precipitative wetlands in Nacogdoches, Texas with some friends. This area had received quiet a bit of rain in the previous week so the water level in the slough we first visited was a little high.  


This slough was very high in organics. In some portions it was almost impenetrable.  


As we laboured through this dense vegetation we finally reached the edge of the slough where our first interesting find was thalloid liverwort which we determined was most probably Pallavicinia iyellii . This liverwort was growing everywhere along the edge of the slough with some species of moss which we could not identify.  


Pallavicinia iyellii    

Next we spotted some Proserpinaca palustris. This beautiful stem plant is overlooked quiet a bit in our hobby. As can be seen in the picture below P palustris prefers highly acidic substrate.  


Proserpinaca palustris     

We also spotted some  Saururus  crenuus in the same acid rich substrate. S crenuus seems highly adaptable to soil conditions as I have also seen this plant grow around Houston in soil with neutral pH.   

Saururus  crenuus   

The slough had a lot of Sphagnum sp moss growing around. Sphagnum sp moss has an ability to acidify its surrounding by taking up cations like calcium and magnesium. I collected a few strands of it to try in my blackwater Cryptocoryne set-up.  


Sphagnum sp  

As we came out of the slough we spotted some very interesting mushrooms and fungi. I grabbed the opportunity to take a few quick shots.  





Our next stop was a precipitative wetland with some spillage form water bodies around .  The highly tanned water was about 6-10 inches deep in places which made the place look  like a black water habitat.

As we entered this wetland habitat I spotted some Eleocharis pravula growing among some dead leaves on the moist soil. This was the first time I had seen E pravula growing in its natural habitat. I was excited.  We also spotted some Eleocharis acicularis growing  here.

E acicularis growing submerged.  

 This location also had a lot of Vallisneria americana . I had not expected to find V americana growing in such acidic water.

Our next interesting find was Ludwigia pilosa. There are a lot of pictures of this plant growing emersed but I was glad to see it growing submerged. This plant has a lot of potential as an aquarium plant. The crown of this plants looks stunning when viewed from the top.

 Looking around more closely we were able to spot some Juncus repens growing in the dark, tanned water. J repens though an easy plant to grow is not easily available through commercial aquatic plant nurseries.

We also spotted another stem plant here which I believe is a  Gratiola sp.

Walking around the swamp we were also able to find some very interesting critters.  First we found the Central/Eastern Newt (Notophthalmus viridescens louisianensis) hiding nicely among the underwater vegetation. The next one was a juvenile crayfish which I believe is a Faxonella sp.

We called it a day around 1: 00 pm and headed out for lunch. Thanks a lot to Darren who took the trouble to show us around.

Cryptocoryne pygmaea

Posted in Cryptocoryne & Lagenandra on November 24, 2009 by Bhushan Dalvi

Cryptocoryne pygmaea spathe

Cryptocoryne pygmaea is a relatively rare Cryptocoryne species from Philippines. It is an easy plant to grow in emersed culture. I have been growing it my freshwater crypt set-up since April, 2009. I used 80% ADA Aquasoil Amazonia and 20% pure laterite as the substrate to grow this crypt.

C pygmaea gets its name due to the very small spathe compared to the size of the plant. At times the kettle can be completely buried in the substrate with just the limb of spathe visible above. The kettle of  spathe in the above pictures was about half buried in the substrate. I had to slightly dig around base to expose the complete kettle.

Noticeable feature of the spathe was the rough inner surface of the limb. The spathe was about 3 cm in size. I wanted to slice open the kettle to take pictures of the male and female flowers but decided against it as the kettle appeared almost fused with the rosette.

If seen from the top the spathe is almost invisible with just the a small part of  limb sticking out. I spotted the spathe developing about 3 weeks back. The spathe finally opened up last Saturday.

Staurogyne sp. ‘Low Grow’

Posted in Emersed Culture on November 22, 2009 by Bhushan Dalvi

Staurogyne sp. ‘Low Grow’ bloom.

I have been growing Staurogyne sp ‘ Low Grow’ for about 8 months in my emersed Cryptocoryne set-up. I have two more Staurogyne species (Staurogyne sp ‘Porto Velho’ & Staurogyne stolonifera ) growing along with this one under similar conditions and this one proves to be one of the slowest growing one for me. When I received a couple of stems initially they were grown submerged. It took a while for them to acclimatize to emersed culture. Finally Staurogyne sp ‘ Low Grow’ decided to flower yesterday. I think a recent increase in photo-period on my emersed set-up could have triggered the bloom.

 Staurogyne sp.’Low Grow’

Staurogyne sp ‘Low Grow’ grow very slowly in emersed culture even under good light. An interesting thing I observed with this species is its rate of growth does not change much even after moving it to a shaded location from a well light location. It grows about an inch every month in my experience under both high and low light conditions.
