Attaching two images of Phlogacanthus thyrsiflorus. This is very common at Tezpur (Assam). It is known as TITA BAHAK in Assam. The plant is supposed to have medicinal properties.

To me it appears like Red Nongmangkha (Phlogacanthus pubinervis) rather than Nongmangkha (Phlogacanthus thyrsiflorus), if the id at FOI is correct.

I think you are correct. The plant must be Phlogocanthus pubinervious.


Are these two different plants ? First picture looks like Phlogacanthus thyrsiflorus only as per discussions in this efi thread.

No sir. They are the same plant.

P. pubinervis is known from Eastern Himalaya and NE India only (Karthikeyan et al. 2009). Further, Checklist of Flowering Plants of Uttarakhand by Uniyal et al. (2007) have also not mentioned P. pubinervis from Uttarakhand. It lists only two species P.thyrsiformis and P.lambertii in Uttarakhand.

I thought of contributing this from Kaladungi which is a part of Corbett Tiger Reserve. Being pollinated (most probably) by birds and that too more than one species makes this an ecologically important species.
For those who have not noticed, it has glands even on the floral parts, my vague guess is that is meant to repel insects.
So also wanted to inform that this plant is also available in Western Himalaya too in the foot hills.


Will you pl. reconsider your Id in view of discussions at  efi thread ?

Ok sir then this should be Phlogacanthus thyrsiformis.

Wild flower from Phuentsholing-Bhutan – efloraofindia | Google Groups : 13 posts by 8 authors. Attachments (3)

I am new in this group, and would love to share the images of wild plants that I have taken during my trips to hills and forests of India. I have little knowledge about wild plants, and can hardly remember the scientific names of the various species. But i am eager to know about the wild flora of our country and that’s why I have joined this group today. I am interested in gaining knowledge on plants of India.
Sharing with you all the images of a wild flower that i found at Phuentsholing (Bhutan) in the foothills of the Himalayas. The flowers were regularly visited by birds like Spangled drongos and Silver eared Mesias, as can be seen in the second and third pics respectively. These birds fed on the nectar from the flowers and probably helped in pollination.
Can someone please give the Id and details of the plant?
the pic was taken on 7th.March,2010.

Phlogacanthus pubinervius from the family Acanthaceae.


This plant is also found in NE India. Phlogacanthus pubinervius
http://www.flowersofindia.Red%20Nongmangkha.html


Nice catch of the birds as well as the flowers…


First time I am seeing a big bird feeding on flower nectar.  The bird in picture is drongo.  In Marathi we call it  Kothwal or gate keeper.


The bird in the pic is Spangled Drongo to be precise, (Dicrurus bracteatus). They do feed on nectar sometimes, otherwise they prefer insects.


But the birds in Foto 2 and Foto 3 look different to me. The tail is different. or am I watching wrong?


…, the bird in picture 2 is Drongo.  Any body please identify the bird in picture 3.


the birds in the second and third pics are certainly different….
the second bird is a Spangled drongo, and the bird in 3rd pic is a Silver-eared Mesia.
The latter is actually a kind of colourful babbler found in the foothills of the Himalayas, and rarely seen by birders…..it moves in small flocks feeding on nectar and insects. They play an important role in pollination.
have a nice time…

It think it’s Phlogacanthus thyrsiformis as per images therein.


The Red Nongmangkha (Phlogacanthus pubinervius) is an evergreen shrub which is particularly showy in spring with its dense upright spikes of of brick-red, tubular flowers. The shrub grows up to 3 m tall, with 4-angled, grey branches, and drooping leaves. Leaves are inverted lance-shaped, 15-25 cm long, with a base gradually narrowing into the leaf-stalk. Flowers are braod-tubular, curved, 2-2.5 cm long, 2-lipped, with 5 nearly equal petals. Stamens protrude out of the flowers. Sepals are 6-8 mm long, bristly haired, bracts 6-12 mm long. Bracts are prominent when the flowers are in bud. Fruit is a cylindrical 4-angled capsule, to 4 cm long. Red Nongmangkha is found in forests, at altitudes of 200-1700 m, from U.P. to Burma. Flowering: February-March.
The bird feeding on nectar is a Silver-eared Mesia.

Yes according to the description given in the mail, it is Phlogacanthus thyrsiflorus. If there would have been a photograph of the whole plant then it would have been more easy to identify it.

Validation Please…. Phlogacanthus thyrsiflorus:
During my recent visit to Renuka Ji (Himachal Pradesh) on an
educational tour, I came across this plant after a long gap. Though it was near the end of its flowering season, I could somehow manage to get its flowers. Pictures were taken from the periphery of Renuka Lake on April 22, 2011.
As per my identification this is Phlogacanthus thyrsiflorus Nees in Wall., Pl. As. Rar. 3: 99, 1832; Syn. Justicia thyrsiflora Roxb., Fl. Ind. 1: 114. Kindly validate the id.


Why not, Phlogacanthus pubinervis?

I am not a botanist. I observe happenings in nature and try to record those in my own way. My basis of identification is plates from different books and inputs from botanist friends.
In this particular case my reference is FLOWERS OF THE HIMALAYA by Oleg Polunin and Adam Stainton. Phlogacanthus pubinervius is described at page no-315. The description is as under, (Plate-99)
Uttar Pradesh to Bhutan. North India. Burma. 200-1700m. Forests. Feb-Mar.
Showy in early spring with its dense cylindrical spikes of brick-red velvety, 2-lipped tubular flowers 8-25 cm long, and with conspicuous bracts in bud. An evergreen hairless shrub to 3 m, with 4-angled grey branches, and with drooping leaves with oblanceolate blades 15-25 cm, narrowed to a stalk. Corolla broad-tubular, curved, 2-2.5 cm, 2-lipped with 5 nearly equal lobes, stamens exserted; calyx-lobes 6-8 mm, bristly-haired; bracts 6-12 mm long. Capsule cylindrical 4-angled, hairless, to 4 cm; seeds disc-like, finely hairy.

Yes sir… It is Phlogacanthus thyrsiformis…not P. pubinervius

Thank you …, You are right. The specimen at FOI doesn’t agree with the images of Phlogacanthus thyrsiformis on GBIF, particularly the details of flower petals. At one time I had searched the web for images of this species, but somehow missed these GBIF images. However, I am quite sure this plant is not  Phlogacanthus thyrsiformis. As I had mentioned in an earlier thread, these two are known to be different plants in Manipur – Phlogacanthus thyrsiformis has well used medicinal properties, whereas the other plant has none. J.R.I. Wood also thought it is a different plant, but was unable to identify it. For the time being I will treat it as an unexplained plant.

it seems its a very important possible antibacterial anti cancer therapeutic
I ham copy pasting a sentence from the abstract of this following paper, link follows
i quote:” The most important of these bioactive constituents present in plants are alkaloids, tannins, flavonoids, and phenolic compounds which were determined by doing the phytochemical tests of the extract, and it was responsible for antibacterial activity.

Fwd: Phlogacanthus of NE India : (Mixed thread): 8 posts by 2 authors. 4 correct images as above

Thanks for reminding about this issue once again. I have been looking at it, and the issue appears to be complex to me.
Firstly, I agree that Polunin & Stainton wrongly identified (probably) Phlogacanthus thyrsiflorus, as P. pubinervius.
Secondly, there seem to be two different plants in Manipur, locally considered to be different. I am atatching pictures of them as Phlogacanthus-A and Phlogacanthus-B.
These two look different to me because
1. the inside of the  flower in Phlogacanthus-B appears to be much more hairy, compared to Phlogacanthus-A.
2. The flower shapes look different to me, although can’t be too sure about that
3. See where the sepals are in the fully open flowers. Look at the bottom flowers in Phlogacanthus-B-2 for example, in comparison to Phlogcanthus-A-1 and A-3.
Description of P. thyrsiflorus in Flora of Brit. India says that bracts are about as long as sepals, not longer. In the description of P. thyrsiformis in some papers, the bracts are mentioned to be much longer than sepals. Makes me wonder if these two are different plants. To me, my Phlogacanthus-A appears to agree with the herbarium image of Phlogacanthus thyrsiflorus at Kew:
http://apps.kew.org/herbcat/getImage.do?imageBarcode=K000950020
but not my Phlogacanthus-B.
To compound the confusion, some papers seems to consider  P. thyrsiformis and P. thyrsiflorus as two different plant. I attach one such paper, where P. thyrsiformis is described as the plant with brick-red flowers, which agrees with my Phlogacanthus-B.
I will be happy to have this issue resolved. This discussion which already happened at efloraofindia doesn’t throw any light on this.


Thanks, …

I have a few points to say in this regard:
1. Pictures like A & B has been posted from Uttarakhand & Himachal from where only Phlogacanthus thyrsiformis (all threads herein) has been reported.
2. You can see the list of species found in India as per latest literature at Phlogacanthus. Only P. thyrsiformis (Roxb. ex Hardw.) Mabb. (
Karthikeyan et al. (2009)) is found. Phlogacanthus thyrsiflorus should thus be a syn.
May be experts like … (who is working on Phlogacanthus), …  can give more inputs in the matter.

I may agree that P. thyrsiformis and P. thyrsiflorus might be the same species, although clear mention of that I could not find,
The main problem is that the plant A and B are treated differently by people in Manipur. A (orange one) is supposed to have medicinal qualities, and is very regularly used in home remedies, B (the red one) is not used for this purpose. This all indicates that they might be different species. Opinion of experts on this genus might help.


Here is response from JRI Wood who works on Acanthaceae, including Strobilanthes, and has published on Phlogacanthus too:

——————–
Thanks for your enquiry.
Phlogacanthus thyrsiflorus and P. thyrsiformis are the same species. The correct name is Phlogacanthus thyrsiformis.
I think Phlogacanthus A (the orange-flowered one) is P. thysiformis and Phlogacanthus B is P. vitellinus (P. asperulus in Flora of British India). It is difficult to be completely sure but I will have a look at the specimens when I am at Kew on Friday next week. You are right about the distinctive character of P. pubinervius. I will see if I can find a Polunin specimen to check this too.


Thanks, … This is a very good feedback.


Did you get any more feedback in the matter pl. ?


Here is his last response:
——————
…. Phlogacanthus (and Acanthaceae) are not very easy to identify without specimens (not so easy with specimens!). Here I have access only to old 19th century specimens and it is not easy to match up photos with specimens. I can do north and north eastern Indian Strobilanthes fairly well from photos but other genera can be difficult!

I will get back to you if I have further thoughts.


These two Phlogacanthus species from Manipur had confused me for a long time. Even Dr. John Wood had not been able to help in this matter. Now in the light of the following paper (by M. Sawmliana et al.):
the Phlogacanthus-A attached by me is Phlogacanthus jenkinsii. The Phlogacanthus-B attached by me (the one with reddish flowers) is the real Phlogacanthus thyrsiformis. This has been confirmed by one of the authors of this paper, Dr. Sudhansu Sekhar Dash.
