… some species of Pterospermum.

Pterospermum species in eFloraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ Biotik/ efloras/ books etc., where ever available)

Seems to be Pterospermum suberifolium.

efi page on Pterospermum canescens (syn: Pterospermum suberifolium(L.) Lam.);

To me these images look similar to the one identified by you as Pterospermum reticulatum in another thread.
Pl. have a look & kindly confirm or otherwise.

for Pterospermum reticulatum the stipules should be lacinate- here it is not found; the bracteoles are lso similar to that of P.xylocarpum not like P.reticulatum

It is Pterospermum xylocarpum (Gaertn.) Santapau & Wagh, of Malvaceae; it is very common in Eastern ghats. Attachments (1)

This was shown in a cultivated garden in Mumbai during Tree Appreciation Walk on 23/2/2014.

Interesting and beautiful post. Never seen the tree.

To me last two images look different from others.

It is Pterospermum xylocarpum

Doubtful ID.

To me also look different from images at Pterospermum xylocarpum (Gaertn.) Santapau & Wagh

I will go with …, after topsy turvy of seeing all the images of these species along with confusing and over lapping keys in different floras and getting them corrected with the help of …

Which Species should I take this as? I’m getting confused.

Pterospermum xylocarpum only as identified by …

… some species of Pterospermum ?

Pterospermum reticulatum ?????

Can it be Pterospermum suberifolium as illustration (No. 1526) & a little details as at: Book link
& Ditribution & little details at: Book link

& as discussed in one of the Indiantreepix thread

Here is the illustration of Pterospermum reticulatum, whose leaves also look similar at (but stated to be threatened & endemic to Western Ghats):
Plantsystematic
& Biotik
& only a little desc. at http://en.wikipedia.org/wiki/Pterospermum_reticulatum
Any other pictures & size of flowers should certainly nail down the Id. Was it a planted one or wild?

Can it be Pterospermum diversifolium Blume ?

Looks like Pterospermum xylocarpum

Thanks, … Does not Flowers look quite big ?

Pl. find the attached file contain photos (photo 0098 dark brown is Pterospermum reticulatum) for sp. id confirmation.

The other fruit 0097 is slightly different. For species confirmation I have put in the same thread.

Date: 29.10.2011, NBNP Garden

Place: Anaikatti (640 MSL) Coimbatore Dist.,

Habitat: Garden
Habit: Tree

Pterospermum sp of Malvaceae (Earlier Sterculiaceae) family. Most probably P. divesifolium

The first picture may be P. canescens, not sure though.
The second picture looks like P. xylocarpum.

Yes it look like P.xylocarpum

Could it be P.suberifolium, if its not a syn.

I agree with … First image may be of Pterospermum suberifolium (syn. Pterospemum canescens Roxb.), while the 2nd one may be of Pterospermum xylocarpum

To it looks like Pterospermum reticulatum, rather P.suberifolium

You mean the 1st image?

all 3 are of same; but the age of the pod differs

But to me looks different from images at Pterospermum reticulatum Wight & Arn. (which is in Vunerable List)

Rather I find these more closer to images at Pterospermum xylocarpum (Gaertn.) Santapau & Wagh
You are requested to have a relook pl. as also … post is of a garden plant.

to me it is P.xylocarpum only as …

Attached are pictures of Pterospermum suberifolium captured at Hiranandani Powai, Mumbai in January 2013.
Requested to validate the ID.

There are two

1. Pterospermum suberifolium (L.) Lam. (syn: Pterospennum canescens Roxb.)

2. Pterospermum xylocarpum (syn. Pterospermum suberifolium Willd.)
Which out of the two are you talking about ?

The 3rd picture shows buds (also a flower) and perhaps bracteoles.

Are “bracteoles” of BSI same as “bracts”( in KEY 4a, 4b, 8a…) of BSI?

I assume what I see in the 3rd pic are bracteoles under the buds. Since these bracteoles are not linear it is not P. suberifolium (L.) Lam.

In the 5th pic capsule/fruit looks like having obtuse angle whereas in the 4th and 6th pics it is not clear to me if those capsules are terete or not.

Moreover, I fail to decide if leaves have oblique or symmetrical base.
I am unable to suggest any probability.

Thanks very much for your analysis.

This garden has 2 trees, both of which are P. suberifolium (I was told). The pics are clicked on 2 different occasions, pics 2, 3, 4 and 7 are clicked in January 2015 and pics 1, 5 and 6 in January 2015. I remember that one of the trees was fruiting profusely in January 2015.

…, I honestly do not know which P. suberifolium this might be as I was given these names by the experts.
Hopefully, this ID gets resolved.

As per efi thread:

1. P. acerifolium has 25 cm long peltate leaves and 15 cm long flowers.
2. P. canescens (syn. of Pterospermum suberifolium (L.) Lam.) has 10 cm long rounded leaves with cream coloured tomentum beneath and 5 cm long flowers,
3. P. xylocarpum has 20 cm long cordate leaves and 5 cm long flowers.

Please provide approx. leaf and flower size so that we could arrive at a probable ID.

There are two Pterospermum Species seen by me with smaller flowers. Will post them.

Can it be Pterospermum diversifolium Blume ?

To me it looks like Pterospermum xylocarpum only

A young sapling of a tree.

Pterospermum Species?

Since leaves variable in size and shape this should be Pterospermum xylocarpum (Gaertn.) Santapau & Wagh or = Velaga xylocarpa Gaertn.

Swamy/New series/ID/90 – Pterspermum sps.: 3 images.
I am forwarding h/w the photos received from Chennai for ID. For me the plant looks like Pterspermum sps.- P. suberifolium. Please confirm the ID or suggest the correct ID.
