No. 20. LEMON- WOOD. Citrus medica. 



var. Limonum. 



Plate II. Fig 15. 



Alternative Names. Citronnier : Lime-tree : Limon : Limoeiro 

 in Brazil (99). 



Natural Order. Rutaceae. 



Synonyms. C. limonum. Risso, and many others chiefly 

 relating to cultivated varieties (see Index Kewensis). 



Physical Characters, etc. My specimen weighs 50 lbs. per cu. ft. 

 Hardness Grade 7, firm : Surface scarcely lustrous, otherwise as 

 the preceding species in all particulars. 



Authorities. Nordlinger (86), vol. ii. p. 14. Hough (49), 

 pait V, p. 27. 



Colour. Lemon or Citron colour, fading to white in the sap- 

 wood which is not defined from the heart-wood. 



Anatomical Characters. Transverse section : — 



Pores. Rather more crowded in the Spring zone of the ring : 

 20-60 per sq. mm. 



Rays. Very numerous, 8-10 per mm. 



Vertical Sections. Pores more often bright lines : Rings 

 rather more readily visible by means of the bands of pores here 

 and there: Soft- tissue fine but clear vertical lines which are 

 horizontal and wavy lines in the Tangential Section. Otherwise 

 the description of C. Aurantium serves in every respect.

thoxylum sp. (Probably Z. flavum. Vahl.) 



Plate II. Fig 16. 



Natural Order. Rutaceae. 



Synonyms. Xanthoxylon. Fagara flava. Kriig.

 Domingo Satin-wood. These names may represent different

 New Providence (111). 



Physical Characters, etc. Recorded dry-weight 51-68 \ lbs. per 

 cu. ft. Hardness Grade 2, compare Boxwood. Smell like that of 

 Cocoa-nut oil. Taste similar but offensive. Solution with water 

 slightly yellowish : gives off a greasy smell as above. Burns well 

 and quietly : the heat expels a copious red juice : embers glow 

 in still air. 



Grain. Very close, dense, even, and smooth like Boxwood. 

 Surface of the ground-tissue bright : little or no "fire."
