Cones 1 to 1½ in. long, nearly globular, erect, very persistent, mostly clustered, sessile; the scale is a mere transverse ridge, but the bract is large and prominent, like a triangular-hastate, dilated leaf. A very handsome tree, from China, which does not succeed very well in this region except in protected situations.
