Discussion:

In this species, not easily confused with any others, the flowers have a long tubular receptacle, unique except in H. tubiflora, which differs in many other characters. Superficially the general appearance of the present species suggests Couepia, but the fewer stamens, the calyx glands, and the hirsute pubescence of the leaf venation all place it in Hirtella.

Collected in flower July and August.
