Youngia japonica[b] - Oriental False Hawksbeard
Native to eastern and southeastern Asia, the plant has become naturalized around the world in tropical and subtropical zones, so today it has a pantropical distribution and it is considered a cosmopolitan weed.

Habit (Photos taken on February 02, 2014 - Victoria, Tx)
Plants have appeared spontaneously in the backyard in an poor lawns areas. It seems to prefer disturbed areas with sun in the morning and more shadow on afternoon. Frequent alongside or close to house wall. Probably for shadow and humidity.
Note the variability in the overall appearance of inflorescence between the first and the last picture above. Last has a very compact inflorescence.
Note: I try to ID the plants accurately. But anytime an mistake is possible. If so, the correction is more than welcome.
