Further to the functional representations of C$^*$-algebras proposed by R. Cirelli, A. Mania and L. Pizzocchero, we consider in this article the uniform K\"ahler bundle (in short, UKB) description of some C$^*$-algebraic subjects. In particular, we obtain an one-to-one correspondence between closed ideals of a C$^*$-algebra $\mathcal{ A}$ and full uniform K\"ahler sub bundles over open subsets of the base space of the UKB associated with $\mathcal{ A}$. In addition, we will present a geometric description of the pure state space of hereditary C$^*$-subalgebras and show that that if $\mathcal{ B}$ is a hereditary C$^*$-subalgebra of $\mathcal{ A}$, the UKB of $\mathcal{ B}$ is a kind of K\"ahler subbundle of the UKB of $\mathcal{ A}$. As a simple example, we consider hereditary C$^*$-subalgebras of the C$^*$-algebra of compact operators on a Hilbert space. Finally, we remark that hereditary C$^*$-subalgebras also naturally can be characterized as uniform holomorphic Hilbert subbundles.
