in Extra-Tropical Countries. 83 



Cereus Quixo, Gay. 



Chili. This stately Cactus attains a height of 15 feet, and is one 

 of the hardiest species. The charming snow-white flowers are fol- 

 lowed by sweetish mucilaginous fruits, available for the table (Philippi). 

 C. giganteus (Engelmann), from New Mexico, which attains the 

 stupendous height of 60 feet, with a proportionate columnar thick- 

 ness, also yields edible fruit, and lives unprotected at Port Phillip, 

 withstanding the sea-air close to the shores, and growing at the rate 

 of nearly a foot a year. It was introduced by the writer many years 

 ago. Columnar species of Cereus rising to a height of 40 feet occur 

 also in Argentina. C. repandus and C. triangularis (Haworth), of 

 the West-Indies and Mexico, together with several other species, are 

 available as hedge-plants in places free from frost. Nee speaks of a 

 Mexican Cactus (probably an Echinocactus) five feet in diameter by & 

 feet in height. 



Cereus Thurberi, Engelmann. 



North-Western Mexico and Arizona in arid regions. Attains a 

 height of 20 feet; the fruits vary in size from that of a hen's egg to 

 that of an orange; it is of delicious flavor, pleasant taste and very 

 nutritious. 



Cerinthe major, Linne*. 



Countries around the Mediterranean Sea. A handsome but 

 annual herb, particularly alluded to by G. Don as a honey-plant of 

 superior value. A few congeners exist in the same regions, among 

 which C. minor (Bauhin) is biennial or pauciennial, and C. alpina 

 (Kitaibel) perennial. 



Ceroxylon andicola, Humboldt.* 



The Wax-palm of New Granada, ascending the Andes to 11,000 

 feet. One of the most majestic and at the same time one of the most 

 hardy of all Palms, attaining occasionally a height of 180 feet. The 

 trunk exudes a kind of resinous wax, about 25 Ibs. being obtainable 

 at a time from each stem; this, after the admixture of tallow, is used 

 for candles. There are several other andine palms, which could be 

 reared in Australian forests or in sheltered positions about our 

 dwellings. 



Ceroxylon australe, Martius. (Juania australis, Drude.) 



Juan Fernandez, latitude 34 South, on the higher mountains. 



Ceroxylon Klopstockia, Martins. 



Venezuela. This very tall Wax-palm reaches elevations of 6,000 

 feet. 



Cervantesia tomentosa, Ruiz and Pavon. 



Forest-mountains of Peru. This tree yields edible seeds. It is 

 likely to prove hardy in lower forest-regions of the warmer extra-tropic 

 countries.
