  We give $Z$-monomial generators for the vacuum spaces of certain level 2
standard modules of type $A^{(2)}_{\textrm{odd}}$ with indices running over
integer partitions. In particular, we give a Lie theoretic interpretation of
the Rogers-Ramanujan type identities of type $A^{(2)}_{9}$, which were
conjectured by Kanade-Russell, and proven by Bringmann et al. and Rosengren.
