TULIP-WOOD 



Uses, etc. " Turnery, furniture and barrel-staves " (78). 

 Polishes almost naturally as it leaves the tool. The shavings are 

 sticky when compressed in the hand and retain the form of the 

 palm . . . planes badly. " May be met with in the form of 

 logs up to 28 in. square free of sap-wood. The tree sometimes 

 attains the height of 100 feet." (78). 



Authorities. McTurk (78), No. 22. Miers (76). Saldanha da 

 Gama (99). 



Colour. Uniform light red or orange-red heart-wood defined : 

 from the lighter sap-wood, which is about 1 inch wide. According 

 to Boulger it is light brown, but he probably confuses it with one 

 of the varieties of L. OUaria. 



Anatomical Characters. Identical with those of L. Ollaria, 

 with the following small differences : — 



Transverse Section. Pores conspicuous from their lighter 

 colour : 8-50 per sq. mm. Rays very many, 13-20 per mm. 

 Flecks present with strongly-tapering fringes (false rays). 



Radial Section. Pores very inconspicuous and difficult to 

 find, slightly lighter in colour, whitish, filled with Tyloses. 



Tangential Section. The rings appear as faint, whitish, 

 angular loops which give the wood a hoary appearance. 



Type specimen authenticated by the Forest Officer to the 

 Government of British Guiana.
