Daggerleaf tree

The daggerleaf tree was a type of plant created via genetical engineering in a joint effort by the Kazarites and the Payav. The had narrow, succulent leaves which held water, and deep roots which could tap water deep below the surface.

A forest of daggerleaf trees were planted on the edge of the Jarol Desert on planet Kazar prior to 2279, where they served as a windbreak and prevented further erosion of the land where a community of Payav refugees had settled. By 2283, following the return of Raya elMora to power on Mestiko, forests of daggerleaf tress were also planted on that planet. (TOS eBook: The Darkness Drops Again)
