Leaves of variable size, young ones much smaller than slightly older ones. This is because the leaves grow alternate on the stem.

The flowers are suspended somewhat precariously from a thin stalk. The usual spur of Balsams is short and straight. An un-opened flower bud poises above beside several long thin seed pods.

Petals pale yellow without orange spots but with some scriptive thin orange lines in the throat. The two long lower lobes have nicks of various shapes whilst the two much smaller side lobes are paler or even white. A small cowl is at the top, which is reddish on the outside.
