Dear All, The name of this species has been changed very recently. Specht & Stevenson (2006) proposed a separate genus status for this species as *Cheilocostus speciosus *(J.Koenig) C.D.Specht (2006: 159) based on a new phylogeny-based classification of the family Costaceae. They choose *C. speciosus *as the type species based on* Banksea speciosa* J.Koenig (1783: 75). But this generic name is a later parahomonym of *Banksia *J.R.Forster & G.Forster and is treated as a homonym. Thus Cheilocostus is a replacement name for *Banksea*. However, already in 1791, Retzius had published a replacement name for *Banksea*, namely *Hellenia *Retzius. Thus, *Cheilocostus *is an illegitimate superfluous name for *Hellenia*.
Dr. Suchandra Dutta (2010) proposed a new combination based on this, as *Hellenia speciosa (*J.Koenig) S.R.Dutta (2010: 152) but she considered the basionym to be *Costus speciosus* Koenig ex Smith instead of *Banksea speciosa* J.G. Koenig thus the combination became illegitimate. However she rectified the mistake and legitmately published the name *Hellenia speciosa* (J. Koenig ex Smith) S. Duta later (Pleione 7(1): 28 - 29. 2013). Goaverts (2013) published the same combination in same year (2013) as *Hellenia speciosa* (J.Koenig) Govaerts unaware of the second publication of Dr. Dutta (Phytotaxa 151 (1): 63–64; 2013). However according to the rule of priority the combination of Dr. Dutta is valid which hadbeen published earlier. Thus the correct name is *Hellenia speciosa (J. Koenig ex Smith) S. Dutta, Pleione 7(1): 228. 2013* *regards* On Friday, 8 August 2014 02:33:12 UTC+5:30, Gurcharan Singh wrote: > > > *Cheilocostus* *speciosus* (J. Koenig) C. D. Specht > (syn: Costus speciosus J.
