Citrus Medica, Linne.* 



The Citron (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 Real Citron. From the acid tubercular 

 fruit essential oil and citric acid can be obtained, irrespective of the 

 ordinary culinary use of the fruit. A large variety with thick 

 rind furnishes candied the citrio-nate or succade. The Cedra oil 

 comes from a particular variety. 



Citrus Limonium, Risso. The Real Lemon. From the fruit of this 

 is largely pressed the lemon-juice, 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 Real Lime. The best lime-juice is 

 obtained from this variety, of which the Perette constitues a form. 

 Less hardy than most other varieties. 



Citrus Aumia, 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. 



Citrus Planchoni, F. v. Mueller. (C. Australis, Planchon, partly.) 



Forests near the coast of Sub-tropic East Australia. A noble tree, 

 fully 40 feet high, or, according to Hartmann, even 60 feet high, 

 with globular fruits about the size of a walnut, called in Australia 

 Native Oranges. The species has 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. 



Cladrastis tinctoria, Rafinesque. 



North America. The wood of this tree produces a saffron-yellow 

 dye. 



Clavaria botrytis, Persoon. 



Europe. This and following are the species, which are admitted 

 for sale among Silesian mushrooms, according to Dr. Goeppert : C. 

 brevipcs (Krombholz), C. flava, C. formosa, C. grisea (Persoon), 

 C. muscoides (L.), C. aurea (Schaeffer), C. palmata (Scop.), C. 

 crispa (Wulfen). Morren mentions as much consumed in Belgium, 

 C. fastigiata (L.)
