handsome tree, about twenty feet in height, bearing abundant rich 
clusters of fruit resembling bunches of black grapes, grows in the 
Ladies’ Garden, Plantation. Bot. Mag. 3089. 
561. O. sp. ? — The Wild Olive ; wild and very common ; grows to 
a tree about fifteen feet in height, bearing immense quantities of white 
fruit, which, in contrast with its dark-green foliage, renders it one of 
the handsomest trees in the Island. M., alt. 3. 
563. O. europaea, Linn. — The true Olive, of which there are two 
varieties in the Island, grows wild and is rather common on some of 
the most rocky and unproductive soils. In the neighbourhood of 
the Briars, about nine hundred feet above the sea, many fine trees, 
reaching a height of twenty feet or more, exist, and at times may 
be seen loaded with fruit. It grows also at Plantation, Longwood, 
and other places of much greater altitude. When it is known that 
the value of olive oil in the English market is about 50/. per tun, 
and that in one year no less than 28,000 tuns of this article are 
imported into Great Britain, it seems remarkable that no effort is 
made either to use the fruit of the existing plant, or to extend its 
growth by cultivation in the Island. — Hab. S. Europe. 
563. O. europaea longifolia, Linn. — Small purple oblong- 
fruited Olive ; a few trees only, attaining the height of thirty feet, 
at Plantation and Longwood ; fruits abundantly. — Hab. Europe. 
564. O. europaea, Linn. var. — Growing at East Lodge. 
565. O. fragrans, Thun. — Sweet Olea; grows to a tree twelve 
feet in height, at Plantation, Oakbank, Bose Cottage, &c., and blos- 
soms well, perfuming the atmosphere for a considerable distance 
around with its delicious fragrance. Cultivated, and rather rare.
