Place: scrub forests of Nanmangalam RF, Chennai

Check Heliotropium bracteatum.


The same plant was posted by me for a few days before. Still the identity is not confirmed. But guessed as H. strigosum by … efi thread
Waiting for some more opinion.


This is Heliotropium scabrum, i think. … plant differs from this one by having narrower leaves and longer racemes, and may qualify to H. strigosum subsp. strigosum


Thanks a lot …! I appreciate ur minute observation. 


Does not match with images at Heliotropium marifolium J.König ex Retz.


To me it also appears to be Euploca ovalifolia as per images herein & as per images at Useful tropical plants.


It does not look Euploca ovalifolia as the structure of the spike is not matching, leaves are also very small


Thanks, … I agree with you.


Can it be Heliotropium bracteatum R. Br. as per keys in An Excursion Flora of Central Tamilnadu, India By K. M. Matthew ?
In From Floral Database of Tamilnadu, it is stated to be found in all districts of Tamilnadu.

I think this could be Heliotropium scabrum as well.

H. scabrum is a highly variable species (I have collected at least three intermediate forms).
This name is currently ‘unresolved’ by TPL but listed here under the accepted name H. marifolium.

The herb looks stunted due to the summer season. It is Heliotropium zeylanicum (Burm.f) Lam., a prostrate herb.


Thanks, … Pictures does not seem to match with Flora of Zimbabwe


… due to acute summer the herb became very stunted, otherwise it will be normal.


Thanks, … I find flower arrangement a bit different.


It may be Heliotropium marifolium J.König ex Retz. as per images herein.

Pl. find the attached file contain photos for id. confirmation.

Location: Kalapatti, Coimbatore
Date: 16.08.2013
Habitat: garden
Habit: herb


Looks like some Heliotropium sp.


This is Heliotropium supinum L. of Boraginaceae, common in E.ghats and as a weed in fields.


To me it also appears to be Euploca ovalifolia as per images herein & as per images at Useful tropical plants.


It looks like Heliotropium scabrum Retz., it is common here.

E.ovalifolia has terminal spike like inflorescence.


Thanks, … But images of Heliotropium scabrum Retz. at Satish Phadke (Id by Shrikant Ingalhalikar) & Anurag N Sharma (Id by P. Santhan & A. Lalithamba) look different from this post.


Can it be Heliotropium bracteatum R. Br. as per keys in An Excursion Flora of Central Tamilnadu, India By K. M. Matthew ?
In From Floral Database of Tamilnadu, it is stated to be found in all districts of Tamilnadu.


For me it looks like a species of Tiquilia  


may not be Tiquilia, the leaf character is not matching


Heliotropium scabrum.


Images in FOI of Buglossoides arvensis are not correct
Pl. see & correct:
These are most likely of Heliotropium marifolium as per images herein.


Thank you …, you are correct, 


 I think you are right, also probably with Heliotropium marifolium
