Interesting leaves. Linear 2-4" long about 20 appearing per whorl giving the impression of an umbrella (hence the common name). Leaves are heavily grooved in the middle on both surfaces. Lower surface lighter green.
What look like small brown bumps or scales on the stems are actually the leaves, and the leaves are modified stems.... according to some botanists anyway.
Woody cones, 2-4" long, green maturing brown.
