Turnera subulata is a species of flowering plant in the
It is commonly cultivated as a garden flower.[4]
Growth
This plant is a perennial herb growing from a thick taproot and woody stem base. It reaches a maximum height around 80 cm (31 in). The leaves are roughly oval in shape with toothed edges. The undersides are glandular and coated in white hairs. The upper surfaces may be somewhat hairy, as well. The leaves are up to 9 cm (3.5 in) long.[3]
Flower
Flowers occur in the leaf axils, borne in calyces of hairy, glandular sepals. The petals are rounded to oval, the longest exceeding 3 cm (1.2 in).[3] They are white or yellowish with darker bases.[2] The dark patches at the bases are nectar guides.[5] The center of the flower is rough, feeling like a cat's tongue.[2]

Fruit and seeds
The fruit is a hairy capsule containing seeds with white arils.[3] The seeds are dispersed by ants, who are likely attracted to their high lipid content.[6]
Appearance
Like most other Turnera,[5] this species is heterostylous, with two morphs. The "pin" morph has long styles in its flowers, while the "thrum" morph has short styles. Both morphs produce the same amount of pollen. One study reported that during pollination, pin flowers receive more pollen from thrum flowers than from other pin flowers.[7] The genes that cause this dimorphism in style size are the subject of current research. So far, it has been established that short styles contain proteins, polygalacturonases, that are absent in long styles.[8]
