I am in doubt whether Dr. Thwaites' P andanopliyllum costatum is 

 identical with this plant, as his short description does not well coincide 

 with the above characteristic. According to that author the achenes 

 are 6 — 12 ribbed, but the Malayan species which I have examined, 

 have them all 6-ribbed only.
