Close-up views:

I first spotted this plant at an open-air carpark near my place in January 2016. This plant was not reported in Singapore then. It was later identified in February 2017 from a wildflower pictorial guide book from Taiwan (都會野花野草圖鑑) published in 2011 (page 79). It was naturalised in Taiwan before 2009 [1]. Now, it is naturalised here [2]. Someone had even asked about its identity in a Straits Time article in January 2019.
