Is this Commelina diffusa?

[dr.rakesh Singh]

Properly oriented photos needed of flower front and side , spathe top and side , leaf , hairs on various parts and habit . 

It is a commelina , C. diffusa or C. caroliniana ......best differentiating character is testa foveolate or reticulate and it will take time before seeds mature and dry .

All comments are complementing each other , highlighting what is required in the process of identification . 

In practical examination at MBBS and above , we have cases of spot diagnosis where .....just look and tell . Fast . Then there are short cases where minimum of examination will reveal diagnosis . We had to look at slides under microscope , xrays etc with classical diagnostic features we had to identify . Then there is long case which we had to take history , do a thorough physical examination , come to a tentative diagnosis or set of diagnoses , and then we were grilled in discussion , proving or disproving them , or how to approach , which investigations to do , what we expected to find out .

 

The business of plant identification I find no different . 

Some identifications will be quick , one look and bingo ! Some will need a little exploration , and some will need thorough examination , at times with a microscope . 

We all are practising this , knowingly or unknowingly . 

Vinay ji has provided good relevant data regarding habitat and plant . 

Pictorial documentation needs be more elaborate yet specific , and it comes only by going through the key of given genus again and again .

I think Mahadeswaraji was referring to the write up

with DatE TIME LOCATION Habitai plant location etc in the original request

Rakesh was refering to what need to show in pics

and Mahadeswaraji was referring to Vinay's writing of the original request where he ga all the prescribed information about the plant in question

its really simple and strait-forfarwad.

Vinay followed the guidelines to the T

no confusion

Ihope Ithis makes it clear?

while I was typing the long paragraph above

Rakesh explained it

it should be quite clear now.

Well said Usha di and Dr. Singh ji.   Coincidentally they have  spoken what is in my mind. What is needed is a combination of both  visual  and text presentation to help the experts to ID the plant.   I myself lack this quality  & would like to improve in my future postings.  Of course,  It is  easier said than done  as old habits die hard !

Good Rakesh

now if you could at your convenience make a table for differential diagnosis for all the species of acalypha in india?

based on your onderfully detailed and some newer ( or not published ) observations that you tld us about

?

take your time

no rush

but  a tabulation would help\

or a flow chart

[dr.rakesh Singh]

Ma'am , all the species !!! Noooo !!! That will be a tall order for which neither I am qualified , nor capable . 

Two and half years back I shifted to Surat city from outskirts and all I see now a days is Acalypha indica growing wild . 

Of course , there are ornamental species more prevalent in private collections , like A. wilkesiana , A. hispida etc .......

they do not require any key . Four species of Acalypha '' I think I recognise '' ........indica . malabarica , lanceolata and ciliata.....

growing wild in Rural Surat I did record 4-5 years back , 

and I have shared my images with key character in another thread . Whether I am right in my assumption or not , experts will tell . 

I must disclose that my approach is hands-on rather than scientific , and  whatever plants I recognise  are mostly by visual cue , I bring in science later .

At times I have difficulty putting it to words what I see and feel . Learning slowly , being hopeful . 

ThanQ for inspiring us novices , showing confidence in me !

I think it may not be possible to id, based on these images, except for experts on this genus.

It is very difficult to ID with these pictures, rightly suggested perhaps as C. diffusa. 

[J.M. Garg]

Catalogue of Life mentions three species with this name.

[J.M. Garg]

Thanks, Mayur ji.

[dr.rakesh Singh]

It certainly is not Commelina communis , since odd petal is pretty big and concolorous . 

I read about it , wikipedia says it is distributed in India too ........I wonder why it is not represented in 

EFI or FOI ! 

[J.M. Garg]

Hi, Rakesh ji,

Catalogue of Life mentions four species with this name.

Only Commelina communis Engelm. ex Kunth, nom. illeg. ambiguous synonym for Commelina diffusa subsp. diffusa is distributed in India.

[J.M. Garg]

Thanks, Rakesh ji.

Sir , Let us ask Mayur Ji about this confusion . To me , presence or absence of prominent concolorous odd petal seems an important character . 

[J.M. Garg]

Thanks, Mayur ji.

Dear Rakesh ji, 

Commelina diffusa is often misidentified as C. caroliniana and with C. communis L., as they shares similar habit. Also called C. nudiflora, frequently. 

You will also find C. communis Vell. (non L.) in synonymy of C. diffusa. 

All the mentioned species has distinct elliptic to orbicular medial petal, which is inconspicuous (or rarely absent) in some Commelina species. For the precise identification I'll prefer spathe and capsule characters, which is missing in the posted picture, therefore tentative ID can be made which is more close to C. diffusa.     

sincerely, 

Mayur
