rather elongated, up to 6'5 cm. long, and at the upper end 
up to 18 mm. thick, with very few filiform root-fibres, brown

fibres. Innovation-bud a very low, broad, obtuse cone ; scales 
very broad with a clasping base, decaying after sprouting. 
Stem several feet high, erect, straight, simple, terete, sparingly
