94 Select Plants for Industrial Culture 



Citrus Medica, Linne. 



The Citron-tree (in the widest sense of the word). Indigenous to 

 Southern Asia. For the sake of convenience it is placed here as 

 distinct from C. Aurantium. As prominent varieties of the Citrus 

 Medica may be distinguished : 



Citrus Cedra, Gallesio. The true Citron. From the acid tuber- 

 cular fruit essential oil and citric acid can be obtained, irrespec- 

 tive of the ordinary culinary use of the fruit. A large variety 

 with thick rind furnishes candied the citrionate or succade. The 

 Cedra-oil comes from a particular variety. 



Citrus Limonium, Risso. The true Lemon. Lemon-juice is largely 

 pressed from the fruit of this variety, while the thin, smooth, 

 aromatic peel serves for the production of volatile oil or for 

 condiments. The juice of this fruit is particularly rich in citric 

 acid. A large variety is the Rosaline-Lemon. 

 Citrus Limetta, Risso. The true Lime. The best lime-juice is 

 obtained from this variety, of which the Perette constitutes a 

 form. Less hardy than most other varieties. The Lime is one 

 of the best and most enduring hedge-plants for warmer countries 

 (H. A. Wickham). 



Citrus Lumia, Risso. The Sweet Lemon, including the Pear- 

 lemon with large pear-shaped fruit. Rind thick and pale; pulp 

 not acid. This variety serves for particular condiments, 

 Citrus trifoliata, Linne. Japan. Much grown as a hedge-shrub 

 in its native country; used often as stock for grafting oranges 

 on. 



Coal-oil proved the most effectual remedy in Florida to dislodge 

 scale from any kind of citrus-plant; half a pint of oil is to be mixed 

 with sifted wood-ashes and then with 6 gallons of water, this fluid 

 to be syringed over the trees. The import of lemons and oranges 

 into the United Kingdom during 1884 was valued 1,782,686. 



CitniS Planchoni, F. v. Mueller. (C. Amtralis, Planchon, partly.) 



Forests near the coasts of sub-tropic Eastern Australia. A noble 

 tree, fully 40 feet high, or according to C. Hartmann even 60 feet 

 high, with globular fruit about the size of walnuts, called in Australia 

 Native Oranges. The species first appeared under the above name in 

 the "Report on the Vegetable Products of the Intercolonial Exhibition 

 of 1867." Its beautiful wood takes a high polish; hence it is made 

 use of for the finest cabinet-work. Through regular culture doubtless 

 the fruit could be enlarged and improved. 



Cladrastis tinctoria, Rafinesque. 



Eastern States of North-America. Yellow-wood. The wood of 

 this tree produces a saffron-yellow dye. 



Clavaria botrytis, Persoon. 



Europe. This and the following are species, admitted for sale among 

 Silesian mushrooms, according to Dr. Goeppert: C. brevipes (Kromb- 

 holz), C. flava, C. formosa, C. grisea (Persoon), C. muscoides (L.), C.
