KAS Week::(Gentianaceae Sp. – 09/10/2012-NJ):
Gentianaceae sp from KAS. Photo taken in third week of September.

Calyx not winged hence Exacum lawii.


KAS Week DS_091012_04:
sorry that I have got this poor image and only one image of this tiny blue flower.
from Kas 22nd Sep 2012.
Can it be identified?

This is Exacum lawii.
The image posted by you is more than help ful for identifying this plant. Since the identification is on winged calyx.
Calyx winged : E. pumilum
Calyx not winged : E. lawii

It will be helpful if anyone can post some images of E. pumilum showing the winged calyx

You can see wings on calyx lobes of buds in the attached image of E. pumilum. Besides E. pumilum flowers are larger than E. lawii.

Seen this small herb (around 10cm) at Raigad Fort (Maharashtra).
Date / time: 21-09-2013 / 10:15AM
Habitat: Wild; in grassland
Habit: Herb (10 cm in ht),
Leaves Opposite, small (approx 8 to 10mm); sessile and thick.
Could this be Exacum lawii???

Agree with you. This is E.lawii since the calyx is not winged.
The key is on calyx :
Calyx wingd : E.pumilium
Calyx not wingd : E.lawii

Requesting to please validate ID – Exacum pumilum – of these blue flowers captured near Satara, Maharashtra in October 2014.
Also, what are the spiny things that are seen in the photograph?

Yes it is Exacum pumilum Griseb.

Thanks … for the confirmation…. Any idea about those spiny things? 

This should be Exacum lawii though calyx (not winged) can’t be seen in the pictures. E pumilum flowers are in cymes and E lawii flowers are solitary on slender peduncles

Thank you … for the ID…
Attaching a cropped pic of the flower showing the calyx I think….
Will this help in conclusively arriving at the ID?

Exacum lawii
calyx is not winged and the flowers are solitary
Kaas plateau

Kas week : Exacum pumilum SMP:
Exacum pumilum

On second thought …it may be Exacum lawii.

This could be indeed E.lawii. But as the key is on winged calyx, the id still remains unconfirmed.

Exacum. sp from Raigad Fort (Maharashtra).

I think this may be Exacum pedunculatum from Gentianaceae

Exacum pumilum Griseb is reported from Flora Raigad dt.

I think close to images at Exacum lawii C.B.Clarke
