Hoya Keysii Flower. Thick gray-green leaves richly felted. The flowers are of the smaller ones among the australis species.
They are all tropical vines. This one is especially succulent likes long dry spells. Keysii is its new name.
Traill and a GW Traill listed on their hebarium so I am pretty confident that Traill is a person.
Hoya keysii blooms with fragrant white flowers. Hoyas are climbing or trailing plants with thick fleshy leaves and clusters of waxy star-shaped flowers. Sent as an unrooted cutting in moss. Waxy white flowers with palest rose corona.
