Any suggestion about the following middle-aged Jaina-source, which describes the origin of the ikkhAgu-vaMsa?
Sakko (=Indra) maha-ppamANAo ikkhu-laTThIo gahAya uvagato jayAvei. 
!!! bhagavatA laTThIsu diTThI pADitA. !!! 
tAhe SakkeNa bhaNiyaM: kiM bhagavaM! ikkhu aku?  aku bhakkhaNe.  
Then the Bhagavan stretched out his dakSiNa hand, 
atIva tammi hariso jAto bhagavantassa. 
taeNaM Sakkassa ayam eyArUve ajjhatthite: 
jamhA NaM titthagaro ikkhuM abhilasati tamhA ikkhAgu-vaMso bhavatu. 
evaM Sako vaMsaM ThaveUNa gato. 
 
There seems ikkhu + aku = ikSvAku-vaMza.  Probably aku means a + ku (not + bad)
´Someone of the listmembers remembers how many knots there are on one sugarcane? Always the same number 2 ? Or different?
Any suggestion?? Probably in connection with the twin-mythologem?
