Wiki description:

New shoots of C. harringtonia remain green for three years after forming and have ribs at the leaf bases. The buds are green in colour, globular in shape and very small at only 1 mm in length. There is one rank of leaves present on either side of the shoot, and these rise up above it and curve slightly inwards, forming a narrow V-shape somewhat akin to a dove 's wings. The ranks are often vertical, but can be more flattened in shaded parts. The leaves are broadly linear in shape and measure about 5 cm long by 0.3 cm wide. They are abruptly pointed at the apex, leathery in texture and a bright matte yellowish-green on the upper-surface. The abaxial surface, or underside of the leaves, shows two broad, pale to silvery stomatal bands. Coloured plate from the book Flora Japonica , by Philipp Franz von Siebold and Joseph Gerhard Zuccarini The species is diecious and the male plants are typically densely covered with pairs of flowers that are pale cream in colour, though they become brown with time, and globular in shape. They are borne on 2 to 4 mm stalks beneath each pair of leaves. Pollen is released from March until May. The female individuals have two pairs of knob-like globose flowers that appear on curved stalks at the bases of the shoots. The fruit is obovoid in shape and measures 2.5 cm long by 1.5 cm wide. They are a smooth and pale green ín colour with dark green stipes, though when ripe they turn brown. An Australian company, ChemGenex Pharmaceuticals Ltd., is developing a leukemia therapy called Omacetaxine derived from the leaves of this yew species.
