larze, 2—3 m. long in the pinniferous part! the petiole about as long, roundish, 
armed with brown ascending flat spines; the rhachis smooth. Leadets narrow, 
subulately acuminate, furnished with black setae only on the mid-costa above. 
Inflorescence cupressiform, shorter than the leaves, the panicle alone 1 m. long or
