Beilsch1niedia angustifolia has opposite leaves and coarse ramification, as all the<br />

Brazilian <strong>species</strong> do. Atnong the Brazilian <strong>species</strong>, this <strong>species</strong> is distinguished by its<br />

narrow elliptic leaves. Width <strong>of</strong> the leaves in B. angustifolia is usually 1/4, at most 1/3 <strong>of</strong> the<br />

length, while width <strong>of</strong> the leaves in n1ost <strong>of</strong> the other <strong>species</strong> is usually about a half <strong>of</strong> the<br />

length or more (B. taubertiana also tends to have narrow leaves, but not narrower than 1/3 <strong>of</strong><br />

the leaf length, and erect pubescence <strong>of</strong> the tenninal buds, twigs and the lower leaf surface<br />

distinguish this <strong>species</strong> from B. angustifolia) . However, leaf shape cannot be the best<br />

character to define <strong>species</strong> because it is sometimes variable. In addition to this character, B.<br />
