In O. pallidus the white flower-tube is almost as long as the calyx, whereas in O. rubicundus the white flower-tube is twice as long as the calyx.

In Orthosiphon pallidus, the corolla is as long as the calyx. The differentiating point between thymiflorous and rubicundus is leaf morphology. In rubicundus the leaf has very short petiole-up to 4mm or the leaf is almost sessile, and in thymiflorous petiole is longer-about 1 to 3cm;

Kindly examine and identify this plant 

Habit: Herb 

Habitat: wild, Semi-evergreen forest 

Sighting: Near Chikmagalur, about 1200 msl 

Date: 07-06-2016


Pl. check 


I see its affinity with Orthosiphon


Probably Scutellaria


Pl. also check 

Not finding a match as per either of the suggested genera. 

Seems like Orthosiphon pallida

Looks like a species of Plectranthus. But not sure.

Orthosiphon sp

Thanks to you all.
I think matches with images at Orthosiphon rubicundus (D.Don) Benth. rather than those at Orthosiphon pallidus

Orthosiphon rubicundus ? : 1 post by 1 author.
During my tenure as D.F.O Bilashpur in Chhatishgarh in the year 2000, I try to understand the traditional use of some medicinal Plant in that area. I came across this type of plant locally called as Kamraj having tuborous root/stem, if it is a herb, it may be some sp. of Orthosiphon. I am attaching some pic of my Orthosiphon rubicundus (experts may pl correct the my id if it is otherwise), which may help you in your plants identification.


These pictures do not match with images of Orthosiphon rubicundus (D.Don) Benth. 


I think these images also must be of Orthosiphon rubicundus (D.Don) Benth.  as per discussions in another thread.

On 17/8/08 in Telekona forest, AP. A smallish herb seen along roadside.


It is Orthosiphon pallidus locally called Jyoti.


To me this looks more like Orthosiphon rubicundus. One distinct difference between O. rubicundus and O. pallidus is that in O. pallidus the white flower-tube is almost as long as the calyx, whereas in O. rubicundus the white flower-tube is twice as long as the calyx.


The differentiating point between thymiflorous and rubicundus is leaf morphology. In rubicundus the leaf has very short petiole-up to 4mm or the leaf is almost sessile, and in thymiflorous petiole is longer-about 1 to 3cm.” from … in another thread http://groups.google.com/group/indiantreepix/browse_thread/thread/4c98df330706a81b?hl=en#
In view I am now taking it as Orthosiphon thymiflorus.


I think it should be Orthosiphon rubicundus (D.Don) Benth. as per keys & images herein.

Lamiaceae species for identification! : 9 posts by 3 authors. Attachments (1)

the photos are attached with of a Lamiaceae member found in the dry deciduous forest of central India, Gadchiroli M.S. It’s a herb, acaulescent. Leaves are 7-15cm around non-aromatic. Flowering in July-Sept.
Requesting you to kindly help in getting ID for the same.


Nice pics, please see for Orthosiphon rubicundus


Thank you, Sir!

But the description provided in flora and the plant in actual doesn’t match with each other not even with Flowers of India and just out of curiosity when searched for relevant images on google, I find a link to a herbarium sheet http://actd.iict.pt/view/actd:LISC060126 this also not matches with it,
The leaves are densely arranged near the base (ground) on a very short stem and it does not show even bolting at maturity.
Kindly consider for further discussion!


Pl. see comparative images at Orthosiphon & details of species found in India.
From this it is seen that there is one Orthosiphon comosus, which certainly looks different.
There is another Endostemon viscosus, which also looks different as per the following:
Comaparative images for other options are available at Orthosiphon, from which it comes closer to Orthosiphon rubicundus (D.Don) Benth. as per images & keys provided herein. There appears to be many varieties as per details. It may be one of them.
Pl. see similar image of one such variety from India at
There seems to be lot of variation in this species as can be seen from the following:
In view, I am confident that it is some variety of Orthosiphon rubicundus (D.Don) Benth. only.


Thank you Sir. You really deserves a round of applause. Your efforts for investigation of this plant’s identification are really noteworthy.

This reflects the ignited passion in the field.
I will investigate further in detail and soon get back to our group with valid and confirm information. Thanks😃🙏
And thanks to all other members and experts for their valuable comments and contribution!
Thanks once again!

Orthosiphon thymiflorus.
This was seen growing besides the road that passes thru Chinnar WLS, Kerala
Chinnar straddles the Nilgiris and falls in the rain shadow area of the Western Ghats


I think more close to images at Orthosiphon rubicundus (D.Don) Benth. rather than those at Orthosiphon thymiflorus (Roth) Sleesen as per details and keys herein.

I used the following infomation as criteria to get the id. the petiole in the photographs does seem longer
As per eflora thread
In Orthosiphon pallidus, the corolla is as long as the calyxThe differentiating point between thymiflorous and rubicundus is leaf morphology. In rubicundus the leaf has very short petiole-up to 4mm or the leaf is almost sessile, and in thymiflorous petiole is longer-about 1 to 3cm;

Just check the images of both with leaf shapes and petioles.
