Notes
The flowers of this species vary in size. The above-cited specimen has the hypanthium about 4.5–5.5 mm. long and the sepals about 5 mm. long and 0.75–1 mm. wide, thus coming under f. tenuis Munz in Proc. Calif. Acad. Sci., ser. 4, 25; 86 (1943), which appears to occur in America over the range of typical F. arborescens, but to be scarcer.Grote 6545!, in the East African Herbarium, was collected from a specimen planted at Amani. From there in the Eastern Usambaras, by distribution to other gardens and perhaps by birds eating the fleshy fruits, it no doubt reached Kifungilo in the West Usambaras. It remains to be seen how completely F. arborescens is naturalized in Tanganyika, but I consider that it merits inclusion in the flora. Botanists in the Usambaras should find out by what exact agency the seeds of F. arborescens are spread.Mr. P. J. Greenway writes that F. arborescens is much cultivated in gardens in Kenya. For this reason further instances of its becoming naturalised should be looked for.
