In a previous article the first two authors introduced a notion of cusp forms for <jats:inline-formula id="j_forum-2018-0150_ineq_9998_w2aab3b7c12b1b6b1aab1c17b1b7Aa">

We show that the space of cusp forms coincides with the closure of the space of <jats:italic>K</jats:italic>-finite generalized matrix coefficients of discrete series representations if and only if there exist no <jats:italic>K</jats:italic>-spherical discrete series representations. Moreover, we prove that every <jats:italic>K</jats:italic>-spherical discrete series representation occurs with multiplicity one in the Plancherel decomposition of <jats:inline-formula id="j_forum-2018-0150_ineq_9997_w2aab3b7c12b1b6b1aab1c17b1c15Aa">
