105. C. Limonum, Risso. — Two varieties of the Lemon, the 
Sweet and the Sour, occur. Formerly the Island was quite 
a Lemon garden, producing fruit in perfection, bib now visitors, 
and mariners after long sea voyages, look for them m vam. Hie 
trees growing old, their roots penetrated thiough the upper soi 
to the rock, and no new ones were planted, so that about 
ten years ago Lemons became a scarce article. The tree once 
grew plentifully in such places as Lemon Valley, Lemon Tree 
Gut, &c., where now scarcely a vestige of one is to be seen. A re- 
planting of this valuable and handsome tree has, however, been 
recently commenced, and promises success It grows to ten 
feet in height, equally well at alt. 1 to 4. Introduced m 1/18.- 
106. C. Limetta, Risso. — Tlie Lime, once so abundant, suffered 
the same fate as the Lemon, and I doubt if a Lime can now be ob- 
tained in the Island. A replanting of trees, however, with proper 
treatment and care, is, I believe, all that is requisite to re-establish 
it, notwithstanding the blight which attacks the leaves ol al the 
young plants of this genus. This blight assumes the form of a black 
deposit over the surface of the leaves, causing many of them to become 
knotty, crumpled, and sickly in appearance. -Hab. Asia.
