Here are some extracts from Wikipedia link: http://en.wikipedia.org/wiki/Chorisia_speciosa

The floss silk tree (Ceiba speciosa, formerly Chorisia speciosa), is a species of deciduous tree native to the tropical and subtropical forests of South America. It has a host of local common names, such as palo borracho (in Spanish literally "drunken tree"). It belongs to the same family as the baobab and the kapok. Another tree of the Ceiba genus, C. chodatii, often receives the same common names.

The natural habitat of the floss silk tree is the north-east of Argentina, Paraguay, and southern Brazil. It is resistant to drought and moderate cold. It grows fast in spurts when water is abundant, and sometimes reaches more than 25 m in height. Its trunk is bottle-shaped, generally bulging in its lower third, measuring up to 2 m in girth. It is studded with thick conical prickles which serve to store water for dry times. In younger trees, the trunk is green due to its high chlorophyll content, which makes it capable of performing photosynthesis when leaves are absent; with age it turns to gray.

The branches tend to be horizontal and are also covered with prickles. The leaves are composed of five to seven long leaflets.

The flowers are creamy-whitish in the center and pink towards the tips of their five petals. They measure 10-15 cm in diameter and their shape is not unlike hibiscus flowers. Their nectar is known to attract insects such as monarch butterflies, which perform pollination. C. speciosa flowers are in bloom between February and May. The flowers of the related C. chodatii are similar in form and size, but their color goes from creamy white centers to yellow tips.

The fruits are lignous ovoid pods, 20 cm long, which contain bean-sized black seeds surrounded by a mass of fibrous, fluffy matter reminiscent of cotton or silk.

The "cotton" inside the fruit pods, although not of as good quality as kapok, has been used as stuffing for pillows and thermic insulation at times.

The wood of this tree is light (relative density = 0.27 g/cm³), soft and flexible, and is employed in packaging, to make canoes, as wood pulp to make paper, and in ropes. From the seeds it is possible to obtain vegetable oil (both edible and industrially useful).

The floss silk tree is cultivated mostly for ornamental purposes. Outside of private gardens around the world, it is often planted along urban streets.

To add to what has been rightly mentioned by Satish, this tree was brought to India only after independence  by the Delhi Horticulture Dept. probably on the recommendation of some VIP who went to South America during its flowering season. The best part is that it flowers at a time when there are hardly any flowers around.  Delhi must have got scores if not hundreds of the trees. NDMC has maily planted it in the roudabouts where it should be a big distraction for tree lovers who are driving! Young plants are available in Sunder Nusery. A good source of Delhi trees is the very well produced book by Pradeep Krishan.

I should clarify that I was pointing out that C. ventricosa and C.
speciosa are distinct species. C. speciosa are quite common here as
well (there is one across the street from my house), but C.
ventricosa is, as far as I know, not in cultivation. I have shots of
different cultivated species here:

Description of the species are available here:

Thanks all for various views.
Basically I was told that this tree is Chorisia speciosa.
On trying to find some information I came across page 484 of"'Further Flowers of Sahyadri''
and saw similar photograph to that of mine mentioning it as Chorisia ventricosa by Shrikant Ingalhalikar and thought that it may be the new name.
As per the links given by Barry the two species are definitely different and I will leave it to experts to find the differences. Anyway it would be nice if someone comes up with images or differentiating points.I will also try to look into details about the flower and the tree.
Thanks
Satish

As per page 347 of Flora of Maharashtra State.(BSI Publication)Dicotyledons Vol - 1.Chorisia ventricosa is a cultivated species.This plant has been labelled as C. ventricosa by Nees & Mart. in Nov. Act. Nat. Curv.1:102 t. 9. 1823 and by Almeida in Flora of Maharashtra page 131 vol.1 1996.It is native of Brazil.The description matches with this tree and flower.Even if the identification is wrong one has to give differentiating key of characters  rather than differentiate by looking at photo.Shrikant Ingalhalikar has used the nomenclature from the above mentioned books and has clarified this.

Here is the description of Chorisia ventricosa from the taxonomic revision of Ceiba:


The key is the white to cream petals. Although highly variable in trunk and leaf morphology, Chorisia speciosa is notable for the pink/magenta of the petals, leading to its wide cultivation in comparison with other Chorisia spp.
