766 PRACTICE OF GARDENING. PART III. 



The names and some descriptive traits of these seventy-four sorts of citrus will be 

 found in A Short Delineation of Dr. Sickler's Treatise, by Dr. Noehden, in the Hort.

4881. Gallesio (Traite du Genus Citrus, &c. Savonna, 1818.) has given a synoptic 

 tree ( t fig. 509.), in which he has introduced ramifications which display an arrangement 

 of the forty principal sorts cultivated in Italy.

4882. The most splendid work on oranges which has yet appeared is the Historre 

 Naturette des (hangers, by Risso, of Nice, and Poiteau, of Versailles. (Paris, fol. 1818.) 

 Here 169 sorts are described, and 105 of them figured, and their French and Italian 

 culture given at great length. They are arranged as sweet oranges, of which they 

 describe 43 sorts ; bitter and sour oranges, 32 sorts ; bergamots, 5 sorts ; limes, 8 sorts ; 

 thaddocks, 6 sorts; lumes, 12 sorts; lemons, 46 sorts; citrons, 17 sorts. 



4883. All the species of citrus endure the open air at Nice, Genoa, and Naples ; but at 

 Florence and Milan, and often at Rome, they require protection during the winter, and 

 are generally placed in conservatories and sheds. The largest conservatory in Italy is 

 that of Prince Antonio Borghese, at Rome, which contains seventy select sorts of 

 agnimi. The largest trees are at Sorenta, Teracina, Gaeta, and Naples ; but the most 

 regular and garden-like culture of the orange, -is in the orange-orchards at Nervi, Mo- 

 naco, and other places in the neighborhood of Genoa. At Nervi are also the orange- 

 nurseries which may be said to supply all Europe with trees ; they are, in general, 

 wretchedly cultivated, and the stocks inoculated in the most unscientific manner ; but 

 the fine climate, strong clayey soil, and abundant manurings, supply in a great degree 

 the nicer practices of gardening. There the names of varieties vary as much as those of 

 gooseberries do in England ; but from upwards of one hundred names, not above forty 

 distinct sorts can be procured. Good plants of the Maltese and other varieties of orange 

 may be procured from Malta ; and some sorts also from Lisbon. From the nurseries
