Leucas zeylanica (L.) Aiton f. : 3 posts by 2 authors.  

FoC has Leucas zeylanica (L.) R. Br. but these illustrations are of Leucas zeylanica (L.) Aiton f. – http://plantillustrations.org/species.php?id_species=600245

Both of the above synonymous?

Correct citation is Leucas zeylanica (L.) Aiton f., Hortus kew. ed. 2, 3:409. 1811 (R. Brown, Prodr. 504. 1810, nom. inval.) as per GRIN (updated in 2014) with comments as below:


  • Brown cited Phlomis zeylanica L. as a member of Leucas but did not actually make this combination in 1810 (Melbourne ICN Art. 35.2)
  • the generic treatment and the species description in Hortus kewensis is not attributed to “Brown mss.” so W. T. Aiton is the author of the name (see Melbourne ICN Art. 46 Ex. 23) 

Thanks … I am not sure whom to follow, TPL, GRIN or IPNI.

IPNI lists it as L. zeylanica (L.) R.Br. …. also noted, as GRIN, “Remarks: Index Kewensis gives R.Brown, Prodr. (1810) 504, but although the combination is indicated by Brown, it is not validly made.”

Whatever maybe it is clear that we/they are talking about same taxon.
