Sir,

I thought my journey (as an explorer) to ‘Convolvulaceae Week’ for the current session ended last night! But this afternoon i chanced upon another member of this family what i think is Ipomoea bona-nox L.

It is a big sized flower with equally big leaves. I think the ID is correct because -

1) my copy of “Plant Groups” (by H. Mukherji) describes it as “a large climber with white flowers....”

2) it conforms the words “giant white moonflower” & “vines and climbers” as have been described in http://davesgarden.com/guides/pf/go/893/#b

3) as i plucked a flower-bud to force open its petals i noticed secretion of “milky juice” and “greenish midpetalline bands” as have been described at http://www.mpbd.info/plants/ipomoea-alba.php

4) But i may be wrong, because there is one similar post at - https://groups.google.com/forum/?fromgroups#!searchin/indiantreepix/ipomoea$20alba/indiantreepix/0snjTZGmjSQ/7jBkq6TqMS0J that suggests otherwise.

Now, it’s before you to validate the ID.

Species : Ipomoea bona-nox L. ???

Good morning Sir.

I too never noticed it before and there were only two buds in one of those plants. Hope there will be many in coming days.

Thank you and Regards,

Surajit

Sir,

It's my pleasure to share any info i am able to collect on our biodiversity. Today i revisited the place and also surrounding area, found more of this plant. I could collect some more data on it -

1) The stem has 'hook' like structure, attaching a photograph

2) A local person said that it blooms in the evening

3) A housewife from the same place said they sometimes make vegetable dishes out of its buds

Regards,

Surajit

Completely new to me.
Very interesting Ipomoea.
Especially the corolla which is deeply lobed unlike others.

Nice photo series , although generally the current legitimate binomial of Ipomoea alba should be used in place of any synonyms...

Thanks for your contributions

Sir,

Good morning.

In the first & second photos i slit open the flower to have a better look inside it. In the last photo (later added) though the flower looks like having deeply lobed corolla. Unless i get some more i won't be able to confirm.

Regards,

Surajit

[surajit koley]

Good morning Sir.

I will use the this current legitimate name (I. alba) from now on.

Good morning Madam and thank you.

[surajit koley]

Sir,

In one of my previous reply i used the term "hook" for those "prickle" like growth on the stem. But "hook" is not a scientific word in this case for sure.

What will be the correct term?

Regards,

Surajit

Hello Surajiy,

      You asked :

"

In one of my previous reply i used the term "hook" for those "prickle" like growth on the stem. But "hook" is not a scientific word in this case for sure.

What will be the correct term?"

I've encountered various terms and none seem to be precise , so they are frequently referred to as soft spine-like protuberances...sometimes encountered on the petiole or main stems of Ipomoea alba but more frequently seen on the closely related night blooming species of Ipomoea muricata.

regards,

Ron

I think soft prickles or tubercles would be more appropriate and often used for these species.

Sir,

Thank you for taking care of my concern. At the time of posting i failed to find this appropriate description of those 'protuberances'. However, i collected a flower-bud of the same plant this afternoon and kept it in a vase in order to monitor it. Attaching a photograph.

Hello,

Yes,the literature often uses the term tubercle for these type of protuberances although most definitions of tubercle specifically indicate that a tubercle is round or rounded :

A tubercle or tuberculum. n. In botany, any root of a class embracing both tuberous roots and tubercles: used specifically by Lindley. n

-cle— suffix forming nouns
indicating smallness: cubicle

Tuberculate: An organism or part of an organism which is covered in fleshy and raised protuberances, also called tubercules.

tubercle n. 1. (Life Sciences & Allied Applications / Botany) any small rounded nodule or elevation, esp on the skin, on a bone, or on a plant.
small eminence, or warty outgrowth ;a tuberlike swelling
[C16: from Latin tūberculum  a little swelling, diminutive of tuber ]


and since the protuberances on Ipomoea alba, Ipomoea muricata and Ipomoea parasitica are usually not truly rounded , I have usually opted to call it like it is e.g. a soft-fleshy spine or thorn-like protuberance because the structures in question are usually not rounded.

regards,

Ron

Good morning Sir.

Thank you for explaining all those new terms (to me). It will take
some time to get used to those.

Interesting species. 

The flower is nocturnal. 

The flower opens in the evening and closes by next morning. 

Regards

Yes Sir, it is nocturnal, and i have watched this by keeping a bud into our flower vase (actually, an empty bottle!). But it couldn't opened up its petals fully. I think it needs a cushion underneath, say, of its own leaves, in order to keep its petals wide open.
