Nous donnons une classification des structures kählériennes quaternioniennes homogènes en termes de tenseurs réels, ainsi qu'une rélation avec la décomposition donnée par Fino en utilisant la théorie des représentations. Nous donnons aussi une rélation entre les modules ayant dimension à croissance linéaire et l'espace hyperbolique quaternionien.

A classification of homogeneous quaternionic Kähler structures by real tensors is given and related to Fino's representation theoretic decomposition. A relationship between the modules whose dimension grows linearly and quaternionic hyperbolic space is found.
