Herb for ID from N Karnataka :  Attachments (1). 6 posts by 5 authors.
Please help ID of this herb found in rocky river bed in N Karnataka in Oct.
Stem angular about 50 cm tall, leaves opposite or whorled at nodes, 3-5 cm, narrowly obovate, acute.
Flowers in globose heads (1 cm) at nodes.
Any possibility of this being Hyptis capitata (Lamiaceae)???
... no dear ..., flower looks different.
I think this should be from Rubiaceae..
It could be Mitracarpus hirtus. Please check this link
I could not proceed with the link but it is indeed Mitracarpus hirtus. Thank you so much for the quick lead.
I think more closer to Spermacoce verticillata L. rather than Mitracarpus hirtus
