This is in Malaysia, from an area previously used for tin-mining. Please help me identify it. Thanks in advance.
hi, i'm so lucky. this plant also found in my research in indonesia. I think its name is Stachytarpheta indica or maybe Stachytarpheta javanica. there's a little difference between them, such a structure of leafe n colour of flower.
Yesterday, after Saltcedar suggested it, I had a look on www and saw Stachytarpheta australis and found this pic with description. Which describes it as "becoming somewhat woody toward base. " http://www.flowersofindia.net/catalog/slides/White Porterweed.html
Thanks for pointing that out. The sample plant seems to have pretty extensive woody stems though, even extending until the tips. I'll be heading back to the site to take a good look again. Hopefully will be able to identify some characteristics that provide a clear distinction of the species;-)
Update: Further observations Flowers - These were predominantly white, with a slight tinge of lavender/lilac which is more apparent towards the fringes of the petals. - The spikes (rachis?) to which the inflorescences are attached to are green, and about 2mm in diameter. The spike surface had hairs, but these were very tiny and barely noticeable, only becoming slightly more evident when moving down and away from the tips of the spikes. Leaves - Membranous and finely serrated at the edges. Both upper and lower surfaces did not have any observable hairs to be seen. Stems - Extensive 'woodification', with most of the stems ranging from the base of the plant till almost the tips being light brown in colour. The only exceptions were those near the ends, i.e. the young green ones which are perhaps 16-20cm in length at most (not counting the spikes, which are attached to these young stems).
