Asteraceae for ID : Golden Gate Park, San Francisco : 11SEP21 : AK – 01<\/a>2: 2 images.<\/p>\n

\n
While going through my California<\/span> plants, I found\u00a0some I had\u00a0missed earlier.<\/div>\n<\/div>\n

Leaves are close to Gerbera.<\/p>\n

\n

Please advice.<\/p>\n


\n<\/div>\n

My best guess is Arctotis arctotoides<\/em> which is in cultivation in the USA (see calflora<\/a>).\u00a0 It is also similar to Gerbera<\/em> and Gazania<\/em> and I am not 100% confident of my identification.<\/p>\n


\n
Your guess seems to be correct as per the link below since the flowers and leaves are both matching.

Pl. also consider\u00a0Arctotheca prostrata<\/span><\/a><\/em>\u00a0as per images and details herein.<\/p>\n

\n

To me appears close.<\/p>\n


\n<\/div>\n
… suggestion of Arctotis arctotoides<\/em> looks closer to me.<\/div>\n
\n

Did you check the link I had sent?<\/p>\n


\n<\/div>\n

Yes, I checked it. Looked a bit different.<\/p>\n


\n
\n

Not the first image, the subsequent ones.<\/p>\n


\n<\/div>\n

Arctotis and Arctotheca are quite similar.\u00a0 The paper by McKenzie et al. 2011 (sciencedirect<\/a>) is quite useful for distinguishing features:<\/p>\n
