Agreeing with Ajinkya.
The (broad and short) leaves remind of Commelina benghalensis.
Please wait for validation.

Hello

And one thing I have forgot to mention apart from Commelina benghalensis only this species having Cleistogamous flowers :)

Nice caption Neha ji and thnx for sharing such a beautiful Spiderwort.

[Dinesh Valke]

Many thanks Mayur ji for correcting my thoughts.

Since we are discussing Commellina I would like to draw the attention of Mayur ji to Commelina uploaded by me some time back. I would be uploading/forwarding it again for your kind consideration.

Neha ji

It is Commelina forskalii, perhaps a typo error by Mayur ji

Thank You all.
But it seems to me that the leave of this plant is shorter than of Commelina forskalii.
Y Not Commelina benghalensis ??
Surely it doesn't matches with the pic at Flowers of India site ( of C.benghalensis ) but it does matches with most of the other pics elsewhere.
Plz clear my confusion.

[Satish Phadke]

Previously we had a lot of discussions on Commelina species.
The key of differentiation is based on the cells of ovary which is difficult in the field.
Many taxonomists objected about the guesses made from morphological characters.
I do not know about any key based on morphological characters.
According to my knowledge and belief two species are common at least in Maharashtra(Common areas around cities Not high elevations and biodiversity rich areas)
Commelina benghalensis : Leaves more ovate, elliptic than long
Commelina forsskalii : Prostrate herb. Leaves more linear oblong than elliptic. Margins wavy.
Please share your observations or otherwise.
Confusion about the spelling is also there
According to The plant List
Commelina forsskalaei Vahl : Unresolved
Commelina forsskalii Vahl : Accepted

I am a little confused after reading the key provided by Dr Phadke

Attaching 2 pictures from my 2 earlier posts both of which were identified as Commelina benghalensis 

1)Post1 of 26th sep 

efloraofindia:''For Id 26092011MR3’’ Wandering Jew Pune

The said plant was >7 cms in length with small(as compared to my next post) lilac flowers leaves more elliptic than long and wavy

picture labeled Commelina bengalensis1

2)Post 2 

efloraofindia:''For Id 06102011MR2’’ ?Commelina bengalensis Pune

This plant was 2-3 cms , leaves more long than broad,not wavy  bigger flowers, blue in color

picture labelled Commelina bengalensis2

Can this plant show these variations?

or are they different

I am confused. Kindly validate

Madhuri Ji,

To me, the first pic looks more like - Commelina benghalensis ( Ovate leaves )
and the second seems more near to- Commelina forsskalii ( lanceolate leaves).

But as Satish Ji said -  " The key of differentiation is based on the cells of ovary which is difficult in the field.
Many taxonomists objected about the guesses made from morphological characters "", May b I m completely wrong here.

[Satish Phadke]

Madhuri ji
Those were my guesses which may be completely wrong and it can't be called as KEY.
It is just fitting with closely  matching  pictures.

Thank you Neha ji for giving me some lead. Yes I can see that there seems to be a lot of morphological variation to consider it as the Key.

Hello to all,

I am very happy to read all the discussion and finally I would like to conclude something 

Madhuri ji your posted pictures First Commelina bengalensis 1.jpg is absolutely no doubt Commelina benghalensis 

But Commelina bengalensis 2.jpg may be Commelina diffusa (most probably) 

May be this key will be helpful to identify few common Commelina's in field .................

1. Spathes with margin free to base ........................................................... C. diffusa 

1. Spathes with margins fused at least basally .......................................................2

    2. Inflorescence (Spathe) solitary, axiallary or terminal.........................................3

    2. Inflorescence composed of several aggregate, axillary or terminal spathe...........4

        3. Flowers white...........................................................................C. suffruticosa 

        3. Flowers blue.............................................................................................5

            5. Spathe funnel shaped.........................................................C. benghalensis 

            5. Spathe broadly ovate...............................................................C. forskalaei

     4. Sheath with rusty hairs at the summit................................................C. paludosa

     4. Sheath lacking rusty hairs .................................................................C. ensifolia 

Thank you 

[Gurcharan Singh]

Thanks Mayur ji for this useful key. One more addition to our database. You may incorporate at the begining of the genus Commelina in our website. If you find any difficulty myself or Dinesh ji will do it.
