alanmin4304 Posted April 25, 2007 Report Share Posted April 25, 2007 Rotala wallichii. Rotala rotundifolia. Both plants are grown next to each other in the same aquarium with 80watts of flourescent lighting. wallichii tends to scarlett and rotundifolia to red under good lighting.

evilknieval69 Posted April 25, 2007 Report Share Posted April 25, 2007 That first pic looks nothing like R. Wallichii..... Wallichii has much finer leaves To me, the first pic looks like rotundifolia, the second, roundifolia Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted April 25, 2007 Author Report Share Posted April 25, 2007 rotundifolia means round leaf as does roundifolia (same plant I think) Quote Link to comment Share on other sites More sharing options...

alanmin4304 Posted April 25, 2007 Author Report Share Posted April 25, 2007 Red pine I think (Mayaca fluviatilis according to Cesarz on the other post) Quote Link to comment Share on other sites More sharing options...
evilknieval69 Posted April 26, 2007 Report Share Posted April 26, 2007 Ive always thought red pine was R. Wallichii??? Quote Link to comment Share on other sites More sharing options...
Plantman Posted April 26, 2007 Report Share Posted April 26, 2007 Ive always thought red pine was R. Wallichii??? you are right. proof below. http://www.aquahobby.com/garden/b_Rotala_wallichii.php http://www.tropica.com/productcard_1.asp?id=032A http://www.freshwateraquariumplants.com ... ROD/BP/RWS i think the top one is Rotala Indica and the bottom is Rotala roundifolia. do you dose iron for the red plant? How much? they look great.

alanmin4304 Posted April 26, 2007 Author Report Share Posted April 26, 2007 I have bought R. indica from at least 3 sources and grown them next to rotundifolia and they have all turned out to be the same. Likewise with wallichii until this lot. No iron and no CO2 and 80watts of 7500K flouros for 16 hours/day. Both plants grown next to each other in the same tank. This is the problem with using common names like oxygen weed, moneywort, pennywort etc. I think indica is the old misname for rotundifolia which is also called roundifolia. I have only been able to flower one sort so cannot be too sure. Hopefuuly in the spring I might get both into flower and see if there is a difference Quote Link to comment Share on other sites More sharing options...

alanmin4304 Posted April 26, 2007 Author Report Share Posted April 26, 2007 I am not familiar with mayaca. I don't grow it as it needs very strong light and soft acid water----none of which I have. I think the name Rotala relates to the way the leaves grow (they rotate around the stalk). Someone who has Mayaca may be able to confirm how the leaves grow around the stalk and see the comparison.

fishboi Posted April 28, 2007 Report Share Posted April 28, 2007 i think the top one is Rotala Indica and the bottom is Rotala roundifolia. i am with plantman on this one. R. indica and .R roundifolia are two different plants, besides from leaf shape difference indica has solitary flowers as to roundifolia has clusters. R. roundifolia and R. rotundifolia are the same. either way first pic is differently not R.wallichii at least not like any i've ever seen anywhere.

alanmin4304 Posted April 28, 2007 Author Report Share Posted April 28, 2007 I would be interested in getting some indica but have bought it from a number of sources and have found it to be the same as rotundifolia. So far I have not discovered any in NZ but would still like to get some. Quote Link to comment Share on other sites More sharing options...
