Bombax insigne at Sagargad near Alibag in Dec 09. The flower colour may vary from white, pink to yellow. This was an unusual colour. The corolla was about 20 cm long, lobes were oblong and stamens were in 5 bundles of 50 each. Abundant nectar flows down the flower and is favoured by the birds.

Though there is a record of the Tamil name ‘Vellai kungiliyam’ for this species (source?), this name generally refers to Boswellia serrata or Vateria indica. An another (appropriate) Tamil name available for Bombax insigne is ‘Kal ilavu’.

yes, I goofed up, … BUT, do not know where 🙂 Would … kal ilavu … be spelt like this கல்இலவு ?
OR better still, is it possible for you to put it in the native script ?

what you have written in Tamil script is exactly correct!…,

It is my pleasure to share few images of Bombax insigne (Malvaceae 

Habit: A large butressed tree 

Habitat: Moist decidous forest fringe 

Sighting: Balehonnur, Chikmagalur, Karnataka, about 1100 msl 

Date: 28-11-2015


Pseudobombax species:
I observed many trees of Pseudobombax flowering on 22/23 Dec 2010 near Rajapur Konkan. I think these are Pseudobombax ellipticum. Pl. validate or otherwise. The trees were totally leafless. Some trees were also spotted in Ambaghat. Pseudobombax ellipticum is a non native tree and originates from Mexico but observing these trees in large numbers raised a doubt in my mind. Is it some other species?

-This is Bombax insigne. Also this is its flowering season.

Bombax insigne !! very rare in bengal but seen few of them.

Nice shots …
I also observed some trees on way to Mumbai.
This is the typical flowering time earlier than that of Bombax ceiba


Few observation in Dec & January (on early flowering):
Below mentioned trees were seen in flowering in last two months..as discussed earlier that the micro change in environment impacts on such early flowering…in Mumbai Wildlife Region.

Bombax ceiba (Dec)
Bombax insigne (Dec)
Butea monosperma (Dec)
Memecylon umbellatum (Dec)
Schleichera oleosa (not flowered, but got new red color leaves) (Dec)

earth’s heating up…..one more proof!!!!
Science mag ran some papers in 1984 and 1985… about the ozone hole and possible global warming… the authors of those papers and editors got taken apart by the “scientists” in payroll of industry and their
fronted Non profits (NGOs in Indian parlance) …. that there was no such thing…. and rest of us despaired about state of affairs of science… and if we the legitimate scientists had any future on this earth…
sorry to see the glaciers disappearing in Alaska and the Himalayas and the Kesuda (Butea) and Shimul (Bombax) flowering in December in Maharashtra…
I wonder if we are too late to be able to reverse some of the damage caused..

even when people r aware globally abt d disastrous impacts of global warming , they keep doing all a same mistakes- playing politics over environmental issues, relentless burning fossil fuels , destroying forests n water conservation on papers.
Yes I think ” we are too late to be able to reverse some of the damage caused.. “

Bombax with yellow flowers – indiantreepix | Google Groups : 7 posts by 5 authors.
Sending you a similar picture of a Bombax ceiba with yellow flowers taken on Tulsi road in the Borivali National Park in Feb 2007.
A pink flowering variety which has longer petals and pods called Bombax insigne also exists.

1) We have a yellow flower tree in Katraj Ghat known as Divyachi Phule (Lamp Flower) is it same as this?
That fowers this month only. Gives deep vilet fruits of brinjal (Vange) type and has cotton.
2) Pink silk cotton is in large numbers in Delhi
3) Singapur silk cotton tree has small lemon colored flowers, grows very fast and the bark remains green. The cotton can be easily harvested as pods dont open immediately

As far as I know it, B cieba has dark crimson flowers while Bombax insigne has yellow/cream flowers.

‘Lutea’ is the term generally used to describe the yellow-flowering variety of a species, but in Bombax insigne the flowers can be either white, pink or even scarlet.

Useful link http://ecoport.org/ep?SearchView&itableId=63001

B. ceiba has both colours – red / pinkish red and yellow. Yellow is not very common, only few trees can be seen at select localities. We have spotted one near Andhra lake. ref to photo by Pravin. – Sawar or yellow silk cotton tree.
B. insigne has yellow, cream, red & pink flowers as seen in different localities. But it flowers before B ceiba somewhere in December – Jan and is uncommon. Photo sent by Neil is B. insigne ie Dev sawar.
Cochlospermum religiosum (In Marathi Sonsawar or Ganer) is different than both above. Sent by …


Red/Yellow silk cotton tree @ Yeoor – indiantreepix | Google Groups : 9 posts by 5 authors. Attachments (2)
During the butterfly festival, i came across both the silk cotton trees Red/Yellow, these both trees were very next to each other.

They are both Bombax insigne. The Yellow Silk Cotton Tree [Cochlospermum reliogosum] is not native to this area [and is therefore not found here in the wild unless planted].

Thanks …, but why is there diff in colouration. If not YSCT then which specie is it?

Bombax ceiba is the Red Silk Cotton Tree. A similar fast growing species B. insigne [found mainly in South India] differs from the above in having a trunk that is usually unarmed, flowers that have larger petals and many more stamens [approx. 400 as opposed to B.ceiba which have only about 75].
Sending you a photograph of the Yellow Silk Cotton Tree [Cochlospermum religiosum] for comparison. Attachments (1)

These trees create a lot of confusion.
Cochlospermum religiosum – Ganer – has yellow flowers but flowers are very different from that of red silk cotton tree. Does it produce silk cotton ? so that it can qualify as Yellow silk cotton tree.
Bombax insigne – Dew sawar – is found in Ghats too. Have seen it growing & flowering at very particular locations on western sides of Ghat roads joining Desh & Kokan in a narrow ‘altitude belt’ (like Bor ghat, Kumbharli ghat, Tamhini Ghat, Varandha ghat, Poladpur) This has large flowers, long petals & long, many stamens. Various colours seen are yellow, pink, bright red, dull red, whitish.
Dew sawar flowers in Dec – Jan while Kate sawar flowers after Feb – generally.
Bombax ceiba – Kate sawar – Red silk cotton tree – is most common. Huge trees with red flowers, spiny barks & branches. Their pods have the famous silk cotton. We have seen & photographed unusual yellow variety of Bombax ceiba. Two – three trees were seen with shades ranging from yellow to pink. But one tree had all yellow flowers.  
one more variety – Ceiba pentandra – popularly known & sold as Sawar – found planted in cities with green, smooth bark & white flowers, hanging green pods. This is not native to Maharashtra but always confused with Kate sawar.

Think you have forgotten to mention the Mexican Silk Cotton Tree, also called the Floss Silk Tree [Chorisia speciosa]. The tree is common along the eastern coast of our country in Tamil Nadu and Pondicherry. It is an fast-growing,ornamental deciduous tree with a greenish bottle-shaped trunk studded with large spines and bears yellowish flowers. C.insignis [White Floss Silk Tree] is also a large tree bearing numerous beautiful flowers at first yellow, later fading to white.

Chorisia speciosa most usually has intensely pink flowers and a yellow throat, although the species is highly variable and there are many cultivars. It is referred to colloquially in the west as the “Pink Silk Floss Tree”.
Two different cultivars:
Chorisia insignis has white flowers, and is much less common in cultivation:

…, chorisia speciosa (pink variety) has been taken up by Horticulture dept of Delhi on a large scale. so many roundabouts in Delhi are full of these trees laden with flowers in Oct. I thought that it was only a few decades back brought from South America. If it is native, I stand corrected.

‘Flowering Trees of Bangalore’ has some lovely photographs of both. I am attaching it.

It can clearly be observed that Bombax insigne has far more number of stamens than Bombax ceiba.

Bombax ceiba L.

It could be Bombax insigne Wall.. Any leaf image?

I too agree with you …


Konkan, MH :: Bombax (?) for validation :: ARK2021-029: 2 images.
Seen this tree in the ghats near Rajapur, Konkan, MH in the last week of December 2020.
I am hoping this is Bombax insigne.
Requested to please validate.

Do you have more pictures. Especially Stamens ?? Looks like Bombax ceiba

Bombax insigne Wallich  ??

I do not have any further pics. This was the only flower on the tree. Considering this was just December (end), I thought this could be B. insigne.
But you may be right.
…, even I thought or rather hoped that it was B. insigne, I have never seen one so far.

Bombax insigne for me
