Lañcana in "kārāpesi tilañcanaŋ" at Dpvs 20, 10 is not clear. We may have to correct reading into lañchanaŋ or lañchakaŋ. Oldenberg in his trsln (p. 211) leaves the word out and remarks: "Probably this passage refers to the three pupphayāna mentioned in the Mahāvaŋsa (33, 22, where Geiger reads "pupphādhānāni tīṇi," with trsln "3 stone terraces for offerings of flowers"), though I do not know how to explain or to correct the word used here(tilañcanaŋ)."
