Naturalisation in Extra-Tropical Gauntries. 135 



Cryptomeria Japonica, D. Don.* 



The Sugi or Japanese Cedar. Japan and Northern China. The 

 largest tree in Japan, the trunk attaining 35 feet in circumference 

 [Rein] and 120 feet in height. Stem long, clear, of perfect straight- 

 ness ; the plant is also grown for hedges ; in Japan it yields the 

 most esteemed timber, scented like that of Cedrela [Christie]. It 

 requires forest-valleys for successful growth. The wood is durable, 

 compact, soft and easy to work ; more extensively utilised in Japan 

 than any other. In the Azores the tree is preferred even to the 

 Pinus Halepensis for timber-culture, on account of its still more 

 rapid growth in that insular climate. Several garden varieties 

 exist. Lives unprotected still at Christiania. Withstands gales. 



Cucumis Angruria, Linne. 



Wild in tropical America, but according to Sir Jos. Hooker and 

 Prof. Naudin perhaps of African origin, all other species belonging 

 to the eastern hemisphere. Annual. The fruit serves for pickles. 



Cucumis cicatrisatus, Stocks. 



Scinde, where it is called " Wungee." The edible ovate fruit is 

 about 6 inches long. Deemed a wild form of C. Melo by Cogniaux. 



Cucumis Citrullus, Serinere.* (Oitrullus vulgaris, Schrader.) 



Indigenous probably only in Eastern Africa. The Water-Melon. 

 It is simply mentioned here, to indicate the desirability of naturalis- 

 ing it in any desert. In those of South-Africa it has become 

 spontaneously established, and retained the characters of the culti- 

 vated fruit. The yield is much increased by irrigation ; fruits up 

 to 70 Ibs. were obtained on the Murray-River [Clarson]. Vilmorin 

 found that the seeds will keep fully six years. 



Cucumis Colocynthis, Linne. (Citrullus Colocynnthis, Schrader.) 



From the Mediterranean regions to India. An annual herb. The 

 medicinal extract of colocynth is prepared from the small gourd of 

 this species. Active principle : colocynthin. 



Cucumis ZtXelo, Linne. 



The Melon. Originally from the country about the Caspian Sea, 

 but some forms indigenous to India, northern and tropical Africa 

 and tropical Australia, if really all the forms united by Cogniaux 

 are con-specific. The best varieties might also be naturalised in 

 sand-deserts, particularly in places where some moisture collects. 

 Melons are marvellously prolific on the floating islands of some of 

 the Asiatic lakes. According to Mr. Clarson, Rock- and Green 

 Melons of 40 Ibs. weight are obtained on the irrigated lands at 

 Mildura, Murray-River. In seasons of drought the Muscat-Melon, 

 introduced by the author into Central Australia, has borne fruit 

 there more amply than any other variety. Vilmorin kept seeds for
