Scrypt-Jane is the name of Floodyberry's library for implementing multiple scrypt derivative algorithms.  https://github.com/floodyberry/scrypt-jane

The algorithm used for mining this coin is scrypt (using Keccak 512) and Chacha as the mixing algorithm, whereas standard scrypt mining uses salsa as the mix function.  The actual functions used from Floodyberry's library for the coin are all from the scrypt-jane-mix_chacha_ files.

It's quite possible to use "scrypt-jane" to create a coin that uses salsa as the mixing algorithm.  Way back in the early days of YACoin, after the source was made available and pocopoco disappeared, the correct name of the function was explained by the developer who took up the reins (Windmaster) to be scrypt-chacha. https://bitcointalk.org/index.php?topic=206577.msg2332885#msg2332885
