Polyalthia longifolia

I did not know this tree is called Devdar in Marathi

Yes Polyalthia longifolia of Anonaceae family.

I think its correct name is P. longifolia var. Pendula, commonly known as Indian Mast tree or Ashupal/Asopalav in Marathi. P.longifolia is another species of spreading branches (instead of erect) not commonly planted in the gardens.

The Marathi name of P. longifolia var. Pendula, is Devdar. I think Do you have a pic of P Longifolia of spreading branches to share and if possible its Marathi name

Ashok (polyalthia longifolia) flowers:
Shot in Bangalore– April 2012.
For the first time, I noticed these flowers on Ashok trees (the ignorance of the lay person!). The trees are blooming all over Bangalore. I saw some very pretty butterflies around this tree- couldn’t manage to photograph them- wonder if they are species whose larvae are normally on this tree…

”Id 30122011MR1’’ an observation False Ashoka tree favorite of green bea eaters, bulbuls and purple sunbirds at Pune:
Pune 30 Dec 2011
Today evening I could spot so many birds visiting the False Ashoka tree . ………..



Drongos in Bengal that I have seen love sitting on top of fences and wire!!!!

False Asoka is asopalava tree in Gujarati… leaves are used for door “toran” for auspicious occassions…


Beautiful capture … the drongo with the forked tail and lovely yellow colored Golden oriole. Yes … I too have seen drongos usually perching on wires. What is fascinating is that it sits still for quite a long time as opposed to the restless bee eater

There is lot of different between drongo and bee eaters. Drongos cant make drastic acrobatics in air like bee eater. So they save energy, one perfect strike is better than multiple strikes and missing most of them 🙂

Let this post be an eye opener to those who claim that ‘birds know which trees are NON-NATIVEs, do not
visit those trees, do not nest or take their nector’.

Yesterday evening I spotted parrots on the same Ashoka tree same spot. I am really amused . Wonder which is the next bird to come.

Polyalthia longifolia from District Jind, Haryana:
This one is Polyalthia longifolia (Sonn.) Thwaites shot from Govt. College, Safidon, Distt. Jind, Haryana. This is a very common avenue tree, I was able to capture it in flowers in May 2011.

I have not seen the flowers of P.longifolia so closely. Superb catch

Polyalthia ¿ longifolia ? (Sonn.) Thwaites
Does P. longifolia grow with branched habit as seen in this post ?
at Veermata Jeejabai Bhosale Udyan on 15 MAY 10 

Yes, this is the typical variety of Polyalthia longifolia (var. longifolia).
The trees with drooping branches are of P. longifolia var. pendula.

Supporting …

Thank you very much, … for providing the clarity regarding the two varieties of this species. Will correct my notes soon at flickr.

Polyalthia longifolia, a common tree in parks, roadsides and gardens in Delhi

Nice set of photographs..


This very commonly planted tree blooms in summers, flowers not easily observed due to their greenish colour and being high on the tree..
I could capture them somehow, from Jind District of Haryana..
Polyalthia longifolia…

Excellent photographs …

Please find photos of Polyalthia spp. leaves, bark and inflorescence at RPRC Botanical Garden, Bhubaneswar.
Leaves are narrow half inch width and 3 – 4 inch in length.
Sorry the some photos are blurred due to strong winds.
Can you please ID the species of Polyalthia ? 

Most probably Polyalthia longifolia..


If there are Common Jay/Tailed Jay butterflies in your area, it is likely that there will be Polyalthia longifolia (MAST TREE/ ASOKA/ DEBDARU ) trees in the area. If you are a good observer you are likely to see Tail Jay laying eggs on Polyalthia longifolia. On careful observation on the leaves you a find larva of Tailed Jay butterfly on the leaves. I had the opportunity to observe the life cycle of Tailed Jay on Polyalthia longifolia. I observed throughout May and up to 12-6-15. Attaching a series of 17 images to cover the life cycle of this beautiful butterfly.

I am at this place since 2005. I knew that forest department has planted Polyalthia longifolia (MAST TREE/ ASHOK/ DEBDARU) on the road side.
Last year during this time I noticed TAILED JAY laying eggs on the leaves of Polyalthia longifolia. And recorded life cycle of few butterflies. This year I was fortunate again to observe this phenomenon. I made few collage to depict my observations. Attaching the first such collage, where larvae of TAILED JAY are depicted. They are feeding on leaves of Polyalthia longifolia.

Very beautiful and careful observation Col … So many changes in a few days, nature is wonderful..!!!

Very nice observations and beautiful collage, …

is it saraca asoka. please confirm

Flowers ?? polyalthia longifolia  ??

Not Saraca asoca.
You must be guessing false asoka … Polyalthia longifolia. The leaves and its undulating margins resemble, but not sure.

Yes, … It is false Ashoka
Polyalthia longifolia.

polyalthia longifolia  ??

In 2013 I saw a large green coloured larva on a Polyalthia longifolia (MAST TREE/DEBDARU)  At that time I did not know that the larva is of Common Jay. I brought that to our residence. But some how it escaped. I studied literature on the host plants for this species of butterfly. I came to know that both Tailed Jay and Common Jay butterflies have same host plants and four of them are here near our residence (Artabatrys hexapetalus , Canangia odorata, Michelia champaca and Polyalthia longifolia). Michelia champaca and Polyalthia longifolia were in plenty on the road side. I started observing these plants and started collecting larvae of different size. Those larvae were fed with the leaves of the host plants. I observed larvae started life on Polyalthia longifolia survives on the leaves of Michelia champaca and vice versa.
I recorded many life cycles of these two butterflies on all the host plants I mentioned above. Last time I recorded life cycle of a Tailed Jay was in 2017. So many Michelia champaca and Polyalthia longifolia came under axe in last few years, that may be the reason I could not record any life cycle of these two species. There are only two plants of the other two host plants. I am keeping an watch.
Attaching a collage of Tailed Jay on Artabatrys hexapetalus.


Polyalthia longifolia three variations.:
On the eflora page of Monoon longifolium there are three variations reported.
Polyalthia longifolia var. angustifolia (branched habit with slender spreading branches)
Polyalthia longifolia var. longifolia (branched habit with slender spreading branches)
Polyalthia longifolia var. pendula (unbranched habit with drooping branchlets).
Now I wonder how to differentiate between the two variations angustifolia and longifolia. Please provide crystal clear picture on this issue. What is the key here? is it related to leaves? 

Please provide link to what you are quoting
The three varieties are very distinct. First two have branching habit with spreading branches. var. longifolia is a tall tree up to 20 m tall, leaves ovate-oblong to ovate-lanceolate, 25-80 mm broad. var. angustifolia is a smaller tree hence the name Dwarf Mast tree, has linear to linear-lanceolate leaves just 10-15 mm broad.

Here is the link:

My photographs may be useful for understanding
1. Polyalthia suberosa 
2. Polyalthia longifolia var. angustifolia
3. Monoon longifolium syn. Polyalthia longifolia આસોપાલવ

I think the following may be useful:


Annonaceae: Polyalthia longifolia (Sonn.) Thwaites: 1 high res. image.
synonyms: Guatteria longifolia (Sonn.) Wall., Polyalthia longifolia (Sonn.) Hook.f. & Thomson
location/date: University of Agricultural Sciences campus, Bangalore, July 1997


Annonaceae: Polyalthia angustifolia A.C.Sm.:

It is not reported from India as per POWO (Shown only as Extinct in Fiji).
I can see some specimens from Lalbagh, Bangalore (onetwothree) in GBIF, which appear quite different from other specimens.
If these specimens are correctly identified (otherwise these look quite close to images of, it must be an introduced species here.

Thanks for pointing this out. I will check my notes, but it does seem to be incorrect, and is probably either Polyalthia longifolia or P. longifolia var. angustifolia. I should note that most of the tree species photographed on the University of Agricultural Sciences campus in Bangalore were planted, in their botanical garden.

We are having 2 tree species of  P. longifolia var. angustifolia in our campus,

The M S University of Baroda, Vadodara, Gujarat.
