Hoya nyhuusiae is an unusual Bornean Hoya species known for its compact elliptic foliage and distinctive white, bowl-shaped flowers.

The leaves are paired, smooth, and elliptic, typically deep green on the upper surface and lighter underneath, with visible netted venation. The original species description records mature leaves at approximately 4–7 cm long and 2–3 cm wide.

The flowers are especially unusual for a Hoya. Instead of the strongly reflexed star shape seen in many species, Hoya nyhuusiae produces white campanulate to bowl-shaped flowers. The inside of the corolla is covered with fine white hairs, giving the blooms a soft, textured appearance.

Hoya nyhuusiae was formally described by Dale Kloppenburg in 2003 from material originating on Mount Kinabalu in Sabah, Malaysian Borneo. The type plant had been grown in Sweden by renowned Hoya collector Torill Nyhuus, and the species was named in her honor.

Torill Nyhuus was an important figure in the Hoya community and participated in several collecting trips through Southeast Asia. She later served as president of the Swedish Hoya Society, and several Hoya species were associated with her collecting and botanical work.

Hoya nyhuusiae is currently recognized as an accepted species native to Borneo, including Sabah and Brunei. It is also notable for occurring at relatively high elevations on Mount Kinabalu, with published records reaching approximately 2,200 meters.
