Authorities. Nordlinger (86), vol. vii. p. 28. Wiesner (131), 

 p. 1002. Cape Settlers' Almanac (19). 



Colour. Quite uniform light yellow. A sap-wood tree. 



Anatomical Characters. Transverse section : — 



Pores. Need lens,, size 4, almost uniform : evenly distributed : 

 rather numerous, 60-240 per sq. mm. : an occasional narrow, 

 irregular zone, poorer in pores : single or often in radial groups 

 of large numbers. 



Rays. Fine but clear in certain lights, size 5, uniform : equi- 

 distant : a pore-width or more apart : slightly undulating, 

 otherwise straight, not avoiding the pores : considerably denser 

 than the ground-tissue : white, tapering to long slender points 

 (or else two sizes) : very numerous, 13-20 per mm. 



Rings. Clear to the naked eye, but really rather vague : 

 boundary, an indefinite narrow zone, poorer in pores. 



Soft-tissue. Many isolated, scattered cells of larger size : 

 irregularly scattered, 80-500 per sq. mm., easily mistaken for 

 small pores. 



Flakes. Sometimes present : very narrow lines. 



Pith. Hexangular or six-lobed. 



Radial Section. Uniform in colour, without alternation of 

 light or dark bands : pores need lens, extremely fine lines : rays 

 readily visible and slightly lighter in colour than the ground: 

 white, much broader than in any true Boxwood. Rings vague 

 and not often traceable. 



Tangential Section. As the Radial, but the rays are vertical 

 lines which are practically imperceptible on account of the lack 

 of contrast : about J inch high : much deeper than in Buxus. 



Type specimens from commercial sources checked by Nord- 

 linger's section ; also from a log received from the Imperial 

 Institute. 



The structure of this wood strongly recalls that of the Celas- 

 tracese, especially as regards the rays.
