Cilacap Asteraceae 3: Another Asteraceae from ricefields in Cilacap. ID is requested.
It is a Sphaeranthus species, most probably S. africanus.
I too agree with ... on Sphaeranthus africanus L.
Can you also tell me what is this weed in the background?
one of Glinus by any chance ?
I think you are correct.
It (the plant in the background) does look like Glinus, more of G. oppositifolius.
Sphaeranthus is known as Bodatharamu in Andhrapradesh is a medicinal plant, also hair tonic Flora Andhrica the first Indian state flora by Walter Elliot is good book as it came after Coromandel Plants and from Anakapalle where Roxvburgh supervised Sugarcane cultivation. Some Biographer has visited Samalkota and Anakapalle in 1911 and I advised him to contact some persons as nobody in India knows where Roxburgh and Koenig worked over 200 yrs ago. It is available as Google Books, I myself got it printed as Facsimile edition by Today-Tomorrow, Delhi copies may be available at Bishensingh, Dehra Dun. Another book Taleef Sharif by Playfair-Unani medicine-These 3 books with foreword to fasimile edition by myself
