Sida for ID :: Aarey, Mumbai :: ARKJAN13- 2 : 1 post by 1 author.

Saw these Sida in the Aarey forest in Mumbai in November 2016. I suspect them to be more than 1 species.
Is it possible to ID them?

I think Sida alnifolia L. or Sida rhombifolia L. for these segregated images.

Is there a mix up in these also ?

Sida rhombifolia L. (?) from Hooghly:

I hope this is Sida rhombifolia L., the Bengali name of which has been stated as LAL-BERELA in the book, Plant Groups, by H. Mukherji.

Species : Sida rhombifolia L. ?

Habit & Habitat : wild herb, about 2 feet, found on roadside, pictures were taken from two individual plants at the same place

Date : 01/09/12 & 03/09/12

Place : Kamarkundu (Hooghly)

Negative. This is Sida retusa. Please check these links for my photographs and our previous discussion on this

Though my flowers differ with your picture of S. rhombifolia at – efi thread, i think my leaves differ with that of your images of S. retusa leaves at – efi thread.

Besides, the following websites informs S. retusa = S, rhombifolia L. or S. rhombifolia L. subsp. rhombifolia –

On the other hand The Plant List informs –

Sida retusa L. is a synonym of Sida alnifolia var. alnifolia – http://www.theplantlist.org/tpl/record/tro-19601817
more synonyms of the above – http://www.theplantlist.org/tpl/record/tro-19603576

I am confused. Attaching one more photographs, a larger one, for your perusal.

Affirmative. This is Sida retusa. [Don’t go by the leaves at the top of the plant. Check the leaves lower down]. As Dr.Almeida explained to me when I posed the same questions to him – retusa means ‘cut’ – its as if someone has abruptly cut the leaves. Whereas in Sida rhombifolia, the leaves are rhomboid.

The images of Sida retusa (your uploads) do perfectly match with herbarium found at – http://ww2.bgbm.org/herbarium/view_large.cfm?SpecimenPK=151598&idThumb=378002&SpecimenSequenz=1&loan=0

I thought my pics resemble with the herbarium at – http://ww2.bgbm.org/herbarium/view_large.cfm?SpecimenPK=151592&idThumb=377939&SpecimenSequenz=1&loan=0. But my inexperienced eyes and lack of knowledge are very likely to deceive me.

Thank you very much for the correct id of this Sida.

You are most welcome … Sending you some of my more recent photographs of Sida retusa.

I understand that my species is Sida retusa, not S. rhombifolia. You know it much better than me. Please, tell me, of the followings, which one is correct –

Sida retusa = Sida rhombifolia L.
Sida retusa L. = Sida alnifolia var. alnifolia
Sida retusa is not connected to any of the above

To complicate matters further….. Dr. Almeida in his ‘Flora of Maharashtra’ classifies this as Sida rhombifolia L. var retusa [Linn.] Masters.

I also noticed Sida rhombifolia L. var. retusa, in the net. To make the matter more confusing Flora of China has four varieties of Sida alnifolia! Too complicated to me.
