A new and endangered species of Decaspermum (Myrtaceae) from east-central Queensland

The new species Decaspermum struekoilicum N. Snow & Guymer is described from Queensland. It is distinguished from Decaspermum humile (G. Don) A. J. Scott in Australia by its narrower and more acute leaves, shorter petioles, and unlobed mature fruits. The new species lacks the,"vertical false septum" that has been reported to occur in the middle of each locule between seeds in Decaspermum, and which has been used in part to diagnose Decaspermum from related genera. Instead, the three seeds that typically occur per locule in the mature fruit are completely surrounded by an encapsulating membrane. Typically, seeds, within the membrane are weakly fused and lack any intervening tissue between them. A key is provided to separate the new species from Decaspermum humile.
