Ipomoea 10OCT09

[Dinesh Valke]

Hello friends,

 

... this Ipomoea is beating me -- the flowers about 3 - 4 cm across -- look like enlarged version of I. eriocarpa ; ID please.

 

Place: Ghodbunder Road near Versova

Date: 10 OCT 09

 

Regards.

[J.M. Garg]

I am having a feeling of this being Ipomoea triloba. I think lobes may not always be three lobes.

In my ealier post, identified as Ipomoea triloba by Dinesh ji himself, lobes were not always three. 

I think saw exactly similar plant in Goa, will post them on processing.

No, Garg ji -- not I. triloba for sure.

 

This flower is about 2.5 - 3 cm; relatively large compared to that of I. triloba's size about 1.0 - 1.5 cm.

And the flower is quite different from from I. triloba.

Thanks, Dinesh ji.

By an chance (though myself not convinced), can it be Argyreia hookeri as per FOI link: http://www.flowersofindia.net/catalog/slides/Hooker's%20Woodrose.html

Garg ji, does not seem to be Argyreia hookeri (here the flowers are 5 - 7 cm, and to me they look different too).

... resurfacing query for ID:


Prashant ... Check for Ipomoea marginata.

me ... But, I. marginata is common in my vicinity, and flowers almost round the year (except during rains).

Garg ji ... I am having a feeling of this being Ipomoea triloba. I think lobes may not always be three lobes. In my ealier post, identified as Ipomoea triloba by Dinesh ji himself, lobes were not always three.

me ... No, Garg ji -- not I. triloba for sure.

Balkar ji

I. arachnosperma is now correctly known as I. dichroa. I was trying to find differences between I. dichroa and I. triloba, but could not with limited resources here in USA. Could you kindly find differences from any book available with you.

[Dinesh Valke]

Gurcharan ji ... you may have already referred this JSTOR link ... http://plants.jstor.org/taxon/Ipomoea.dichroa
Regards.

[Dinesh Valke]

... to me, Balkar ji's plant looks to be Ipomoea triloba.



Going through descriptions found at JSTOR for

IPOMOEA arachnosperma Welw. ... Sepals lanceolate, 1.2–2.2 mm. long, 2.5–3 mm. wide, ... http://plants.jstor.org/flora/ftea001271
Ipomoea dichroa Choisy ... Sepals lanceolate, 1.2–2.2 mm. long, 2.5–3 mm. wide, ... http://plants.jstor.org/taxon/Ipomoea.dichroa

... the sepals are more wide than long ... which is found otherwise in Balkar ji's plant.



in this respect, agrees with:
Ipomoea triloba Linn. ... sepals long-ciliate, ... http://plants.jstor.org/flora/fwta6509


BUT my visualization may be all wrong.

[Balkar Arya]

Dear Gurcharan Ji
i could find differences as
I dichroa - Leaf-blade deeply 3-lobed, rarely entire, 5–13 cm. long, 6–13 cm. wide, acute or acuminate at the apex (in JSTORE)

I dichroa Leaves broad ovate, cordate, silvery white-wooly beneath flowers pink or rosy in lax cymes
( as in Flora of Delhi)

i am attaching a page from flora of delhi and a page from further flowers of sahyadri for description of dichroa, marginata eriocarpa and triloba

[Tabish]

To me too, Balkar's plant look like *Ipomoea triloba*. Compare with
the following pics:

I also got the differences

Ipomoea dichroa                                                                                           I. triloba

Plant  densely covered with white or yellowish hairs                              Plant glabrous, nodes hairy

Leaves 5-13 cm long, 6-13 cm wide                                                         Leaves 2.5-7 cm long, 2-6 cm wide

Leaves bristly-pubescent above, white-tomentose beneath                Leaves glabrous or sparsely pilose

Bracts 7 mm long                                                                                          Bracts minute

Sepals bristly or setose                                                                               Sepals unequal,  glabrous or sparsely pilose

Capsule ovoid, 8 mm long, pubescent above                                          Capsule globose, 5-6 mm, bristly pubescent,  apiculate

Though the original plant identity is still elusive for me, Balkar ji's plant is clearly I. dichroa (syn: I. arachnosperma; I. pilosa)

Perhaps this will answer Pankaj ji's query

Seeds velvety-white-pubescent  (in I. dichroa/aracnosperma/pilosa)

Thanks Gurcharan ji,
I had failed to see the details - the hairiness of Balkar's plant
is starkly different from that of I. triloba!

[Dinesh Valke]

Many thanks Gurcharan ji for bringing about the clarity among two species.
It actually set me to check whether there are any I. dichroa in my collection among I. triloba ... http://www.flickr.com/search/?s=int&w=91314344%40N00&q=Ipomoea+triloba&m=text

Regards.

[Balkar Arya]

Gurcharan Ji Dinesh Ji and Tabish Ji
Many many thanks for solving the puzzle

[Gurcharan Singh]

Dinesh ji

I think none.

Welcome Balkar ji ... but please ID my Ipomoea !!!!!!! :)
Regards.

[Balkar Arya]

Sure Sir We all are trying

[Dinesh Valke]

Balkar ji ... it was in lighter vein !!!
Regards.

[JM Garg]

Can it be Ipomoea sagittifolia Burm. f. as per images herein. Leaves are quite variable ?

[dr.rakesh Singh]

This ipomoea is being reported from MH , TN , GJ ......this very closely resembles a species from Brazil named Ipomoea piurensis , and another from Africa named Ipomoea acanthosperma , sources claim two to be synonymous .
This species is very different from all the species mentioned earlier in conversation. I am fortunate to have it in my city and I am studying it for last 4 seasons.

[J.M. Garg]

Thanks, Rakesh ji.
