REMARKS

Scolopia septentrionalis is a large shrub or small tree (“arbuste”); the fruit may be reddish. It may be distinguished from other species of the single-flowered xerophytic group by its small and narrow leaves; it also has far fewer stamens than S. calcicola , which occurs nearby.

CONSERVATION STATUS

The preliminary assessment of the conservation status of Scolopia septentrionalis is Critically Endangered (CR B1ab(iii)+B2ab(iii)). With an Extent of Occurrence of 16 km 2 and an Area of Occupancy of less than 10 km 2, S. septentrionalis is known from only a single location, the Sahafary forest, which is unprotected and subject to continuing degradation. It has not been recollected for almost fifty years.
