I am not sure about the leaves though. The links below show Vernonia cinerea which is found in Asia. Do the blooms look anything like these? It may be a different type of Vernonia. Vernonia cinerea: http://www.leafvein.net/plant_page/compositae/Iron-weed.htm http://www.conabio.gob.mx/malezasdemexico/asteraceae/vernoni... http://www.treknature.com/gallery/Asia/Thailand/photo169052... There are over 1000 species of Vernonia. Here are a few more that are found in Asia: Vernonia cockburniana, Vernonia unicata, Vernonia zollingerianoides (with this last one only found in Indonesia).

A fairly common plant in disturbed areas. htop San Antonio, TX (Zone 8b) January 05, 2009 08:02 PM Post #5970779 I found that its proper scientific name is now Cyanthillium cinereum with Vernonia cinerea being a synonym.

Please post a photo of the plant with the red blooms that look like the Vernonia. Somewhere, I read that the Vernonia blooms could be reddish also. euphorbia4 jakarta Indonesia January 07, 2009 11:00 PM Post #5979788 hi, htop..here are some of the pictures that i was told about, i don't know if this plant is Vernonia zollingerianoides or not..but from the seedpod, it looks more resemblance to the seedpod of Vernonia cineria, a group of flowers bloom more reddish... but didn't bloom well.

Metrosideros Keaau, HI January 08, 2009 04:36 PM Post #5982369 Euphorbia4's last plant looks like a Boerhavia. Maybe Boerhavia repens. suse Bretten Germany January 08, 2009 09:36 PM Post #5983400 Always thought, that must be in the Nyctaginaceae family.

Your plant is an exact match for Boerhavia repens in: Mark D. Merlin, "Hawaiian Coastal Plants and Scenic Shorelines". And in: W. Arthur Whistler, "Flowers of the Pacific Island Seashore". And in: Warren L. Wagner, et al, "Manual of the Flowering Plants of Hawai'i". euphorbia4 jakarta Indonesia January 10, 2009 03:40 AM Post #5988014 thankyou metrosideros for the info..
