Urticaceae looks like a good bet.

I have this same thing. It spreads through runners, can make big clumps. and the flower/seeds are slightly prickly. I've been digging up and pulling out this stuff for the longest. :(

Thanks for that sir/mam!... uhm, I think you're really good at identifying plants/weeds :D .,uhm., can you tell sir/mam what GENERA do you think it is more closer?

sir/ma'am queenb., do you know the name of that plant sir/ma'am?.. even just the name., or scientific name if you know.. I really need its name.. :(

Looks like something in the mint family...monarda, pennyroyal, something with the whorl-type flower heads...horehound is fuzzier...

No, I don't know the name of the plant. I wish I did. :(

[IMG]http://i45.tinypic.com/10e24wn.jpg[/IMG].. I'm still looking for its genera., like what sir/ma'am saltcedar said.,I think it is really Urticaceae.. http://www.phytoimages.siu.edu/taxpage/0/family/Urticaceae.html

oh :( .,it's okay sir/ma'am queenb.., I hope someone could help me.. :(

sir/ma'am., for those who are expert or little expert of identifying plants.. please help me., Its leaves are like Nettle but it doesn't have spiky brown-green flowers/seed.. If someone knows this plant/weed.. I really need its common name or scientific name... I think it belongs to Urticaceae but I don't know what GENERA it is more closer... http://www.phytoimages.siu.edu/taxpage/0/genus/Nothocnide.html ............... for those who can help me., thank you very much in advance..

Boehmeria perhaps owing to the opposite foliage in that genus.

Thanks a lot again sir/ma'am saltcedar!., your answers makes me more closer to my goal..,the real scientific/common name of the plant...I'm now searching for the specie of the plant., from Urticaceae family....Boehmeria genus ... and the unidentified specie... the only problem is the leaves and flower/seed .. the green to brown spiky flower/seed...uhm., if you find the specie sir.. thanks again., but I'll also do my best to find it... maybe this will help sir.. http://www.theplantlist.org/browse/A/Urticaceae/Boehmeria/ ..... Thanks agaiN!

How about Mulberry Weed, Fatoua villosa? A relatively new arrival, so it's not in most of the ID books. It showed up for me in a potted plant.

In the Moraceae.

Mulberry weed = alternate leaf arrangement.
Op's plant = opposite arrangement.

Thanks for your answer sir/ma'am weedwoman.,I saw the picture and there is really a big similarity..,but like what sir/ma'am saltcedar said.., Mulberry weed has alternate leaf arrangement and I think the leaves and flower/seeds are not the same too.... maybe this is a close family of the plant I'm looking for....Thanks for the information you gave.,hoping to find out the information about the plant...

Sorry - I haven't a clue but just reminding people that the OP is in the Philippines.

oh., it's ok sir/ma'am flora uk.... I really need to find its name... hoping that someone knows it...

MerWin - I only wrote the reminder because you were getting some suggestions which implied people were thinking of US plants, not tropicals.
