| The Flowers in P. dasycaulon is comparatively small, hermaphrodite, short pedicellate, complete, zygomorphic, pentamerous, polypetalous, hypogynous and light cream in colour. |
| The gynoecium is on the median plane of these zygomorphic flowers and not oblique as described in taxonomic literature. |
| For example, the weakly zygomorphic flower is scarlet, shows diurnal anthesis and has a backwardly curved labellum. |
| Alternatively, the gynoecium of a zygomorphic flower can be on the median plane of the flower, but the entire flower can be oblique to the axillary plane. |
| Zygomorphic flowers are monosymmetric having a single line of symmetry. |
| In Pelargonium the flower is zygomorphic with a spurred posterior sepal and the petals differing in size or shape. |
