in India than Phaseolus radiatus and Cicer arietinum. Some of the 

 tribes of Central Africa use the stem of this shrub in friction with 

 reeds, to strike fire, according to Speke. Several species of Cajanus 

 of the Atylosia-section, partly indigenous to the warmer tracts of 

 Australia, might be tested for the sake of the economic value of their 

 seeds. The insect, active in the formation of Lac, lives extensively 

 on the Cajanus, according to Mr. T. D. Brewster, of Assam. Silk- 

 worms also live on it. 



Cakile maritima, Scopoli. 



Europe, North- Africa, North- and South- America, extra-tropical 

 Australia. Not unimportant for aiding to cover drift-sand anywhere 

 on low sea-shores ; not hurt by the spray. Regarded as antiscor- 

 butic. In Norway hardy to lat. 71 7' (Schuebeler). 



Calamagrostis Canadensis, Beauvois. 



North- America, extending over the greater portion of the territory 

 on wet ground. Tall and perennial, encouraged rather than culti- 

 vated as a nutritious meadow-grass. Much cut on the prairies, 

 yielding a heavy crop of hay [Sereno Watson]. 



Calamagrostis longifolia, Hooker. 



North-America. Excellent for fixing drift-sand. C. Epigeios 

 (Roth) and C. Halleriana (De Candolle) serve the same purpose 

 according to Wessely. 



Calamintha Nepeta, Hoffmansegg. 



From England to the countries around the Mediterranean Sea ; 

 fond of limestone-soil. It is strongest in odor among several 

 species, but not of so pleasant a scent as C. incana (Boissier) and C. 

 grandiflora (Moench) ; closely allied to the following. 



Calamintha officinalis, Mcench. 



Middle and Southern Europe, Middle Asia and Northern Africa. 

 A perennial herb, used like Melissa as a condiment. 



Calamus acanthospathos, Griffith. 



Himalaya, up to 6,000 feet. A hardy climbing palm. The old 

 canes are leafless. The light but strong suspension-bridges, by 

 which the large rivers of Sikkim are crossed, are constructed of this 

 palm. It supplies material for the strongest ropes, to drag logs of 

 wood from the forest. Most durable baskets and rattan-work of 

 chairs are manufactured from the slit stems. Walking sticks and 

 riding sticks, made of this species, are exported from Sikkim in 

 considerable quantity. Many other Calami serve similar purposes, 

 but probably few or perhaps none are equally hardy. Where 

 climatic conditions for culture do not interfere, the famous C. Rotang
