PURPLEHEART 



per cu. ft. Hardness Grade 2, compare Boxwood. Smell or 

 taste none. Burns well, embers glow in still air, and consume 

 exceptionally slowly : the heat brings the purple colour out. 

 Solution with water dark brown. 



Grain rather coarse and open. Surface comparatively dull : 

 rapidly becomes purple upon exposure. A log received in a 

 very wet (green) condition turned colour before my eyes after 

 being sawn in half. 



Bark. Resembles that of Beech but is of a brick-red tinge ; 

 about J inch thick. 



Uses, etc. " Mill-beds, mortar-beds, house- framing, and all pur- 

 poses where shock has to be resisted — durable " (78). " Ramrods, 

 buhl- work, marquetry, and turnery" (48). "Less durable than 

 Kooroobooilli ; capable of resisting great strain ; may be met 

 with in logs from 100-120 ft. long by 30 inches in diam., free of 

 sap-wood" (72). Almost invariably confused with the other 

 species of purpleheart, but never with anything else.

Colour. Brown heart-wood turning purplish on exposure ; 

 well but not sharply defined from the dirty-white sap-wood. The 

 phenomenon of the change of colour is evidently due to oxida- 

 tion. It is quite superficial as when freshly planed the surface 

 is brown and the purple colour disappears when the wood is 

 polished with a spirit varnish. 



Anatomical Characters. Transverse section : — 



Pores. Conspicuous and large, size 1-2 (or rather larger), 

 varying in no particular order in the individual ring, but the 

 average size increasing as the tree ages : uniformly scattered : 

 few 1-6 per sq. mm. : single, or in pairs or threes ; often filled, 

 beautifully round when not subdivided. 



Rays. Clearly visible, size 5-6 : uniform : more or less 

 equidistant, about the width of a large pore apart (sometimes 

 less) weak but otherwise straight, scarcely avoiding the pores : 

 numerous 5-7 per mm. : very short, frequently tapering both 

 ends : whitish : much denser than the ground- tissue. 



Rings. Doubtful : the fine, whitish lines may indicate the 

 boundary. 



Soft-tissue. Abundant, chiefly in large, spindle-shaped patches 

 enclosing the pores or joining two or more groups. The most 

 prominent feature : perhaps the fine, whitish, concentric fines 

 may also be soft-tissue.

Radial Section. Considerably lighter in shade than the 

 transverse section, the pores are inconspicuous though large, and
