XEROPHYTA 329<br />

The species is found in shallow soil <strong>and</strong> crevices on<br />

granite inselberg <strong>and</strong> also in Com miphora bushl<strong>and</strong> on red<br />

soil between 1300 <strong>and</strong> 1400 meter. It is only known from<br />

Sidamo floristic region in <strong>Ethiopia</strong> <strong>and</strong> has otherwise a<br />

very disjunct distribution, reoccurring from Zambia <strong>and</strong><br />

southwards. These relations should be further studied.<br />

4. Xerophyta spekei Baker<br />

The species is named after the soldier <strong>and</strong> explorer<br />
