G. linearis: Stem absent or very short; heads 4-7 cm across on up to 35 cm long scapes; teeth of involucre as long as or linger than tube, linear-subulate and very finely pointed; leaf-margins mostly revolute..; .
The telling difference between Gazania and Arctotis is the outer involucre bracts which form a tube in Gazania whereas they are usually free or slightly united at base only;

Is it Gazania rigens as I could not find Gazania ringens in well known sites like The Plant List, GRIN, dave’s Garden etc. ? Yes …, you are right. Gazania rigens . Asteraceae Fortnight Part I-Radiate Heads: Ornamentals- Arctotis fastuosa for validation- NS 31 : Attachments (2). 5 posts by 4 authors. Though the pics attached are not well exposed, still I wasnted to know the identity of this ornamental shot from near Ranikhet… I hope this can be an Arctotis sp. Looks like Gazania rigens! It will be very kind of you if you provide key(s) to differentiate the two genera – Arctotis and Gazania. This ornamental in this thread looks like the one i have – efi thread. .

I have already placed my queries in those above mentioned posts. You might have noticed it too.
Gazania
Let’s assume the above two linked plants are Gazania. The Plant List has several species from the genera. My concern is only two, because all i could gather some info is based on the following two species –
Gazania linearis (Thunb.) Druce
Gazania rigens (L.) Gaertn.
Arctotis fastuosa Jacquin
The telling difference between Gazania and Arctotis is the outer involucre bracts which form a tube in Gazania whereas they are usually free or slightly united at base only.
As for three species of Gazania under discussion, they are described under two different species in both books by Bailey.
Bailey (Manual of cultivated Plants) described B. longiscapa DC., considered as synonym of G. linearis (Thunb.) Druce in Hortus third as well as in Plant List.
Similarly G. splendens Moore is considered as synonym of G. ringens R. Br. in both books by Bailey and the Plant List.
G. ringens: stem distinct, with 15-30 cm long ascending branches; heads 6-8 cm across, on 10-15 cm long
peduncles; teeth of involucre much shorter than tube, linear and acute; leaf margin not revolute.
G. linearis: Stem absent or very short; heads 4-7 cm across on up to 35 cm long scapes; teeth of involucre as long as or linger than tube, linear-subulate and very finely pointed; leaf-margins mostly revolute..
Thank you Sir, i am adding this thread to the “key“. …, thank you.

To me also appear close to images at Gazania rigens      
                Hooghly Today : Gazania ?: (17 images) This is small (below 1 ft. high) ornamental and all plants seems to belong same taxon. Gazania splendens! Very wonderful ground cover using all over the middle east for gardening purpose. It is a perennial plant with gorgeous flowers. We have many varieties in Riyadh, KSA Very beautiful flowers … This plant is also good for hanging pots. Thank you very much .., they are very beautiful indeed. FoI hosts more spectacular ones . Gazania rigens (L.) Gaertn. (Asteraceae) It is Gazania rigens (G. splendens), not G. linearis, for the later should be yellow or orange only. Do not know other differences. Please have a relook at the plants in this thread, as per the key in – efi thread. I’m attaching bigger pictures.
Though the leaves in these plants are variably involute, the same can be seen in Lucid Central image (source : Lucid Central) You provided the difference between the two species of Gazania in the thread – efi thread.
One key point of Gazania ringens is presence of white spots at the base of ray florets (which is absent in G. linearis) – Lucidcentral. These white spots are absent in my flowers.
Yet, I agree with …, it is G. ringens, because it is cultivated and involucre is similar to those at lucidcentral site.
I had grown a few here a few years back. Thank you, Sir ji, the lucidcentral site says hybrids of the two taxa, ringens and linearis are also thought to be present in naturalized population. I wonder if these ornamentals came from those hybrids!
