The fruit is covered with soft spines like a chestnut, reaching 3 inches in diameter and turning yellow at maturity. The seeds germinate naturally after they fall to the ground and sometimes present a slight weeding problem. The leaves have an uneven surface because of the depressed veins. They reach a length of 6 to 10 inches. The volunteer seedlings can be used for propagation, or seeds may be sown in flats or Figure 6

Oncoba spinosa Forsk. Spiny Onoaba (fig. 67) Flacourtiaceae Another plant which under favorable conditions becomes a small tree, is the spiny oncoba. At Mayaguez in a clay soil it has remained a shrub for at least 6 years, reaching a height of 8 feet with an equal spread. It is native to Africa and Arabia and is grown elsewhere because of the large, white, fragrant flowers. The numerous thorns and frequent branching habit would enable this plant to function as live fencing. In planting the home grounds, it should be restricted to locations where it is not important to limit the height. In the description in Macmillan (10), the flowering date is given as April to May, but in Puerto Rico the flowers appear in June and July. They are carried individually, chiefly at the branch tips with 9 to 11 petals, and spread to a diameter of 3 inches. A mass.
