3. ISLAND CEANOTHUS — Cteanothus arboreus Greene 



This small tree or shrub is confined, so far as known, to the islands near the 

 coast of southern CaUfomia. 

 It becomes as much as 8 me- 

 ters high, with a trunk 2.5 

 dm. in diameter, and is also 

 known as Tree myrtle. 



The young twigs are angu- 

 lar, densely white-velvety, be- 

 coming smooth, round and 

 brown. The leaves are ovate 

 to eUiptic, blunt or pointed, 

 finely toothed, thick, strongly 

 3-veined from the obtuse base, 

 5 to ro cm. long, dark green 

 and finely velvety on the up- 

 per side, densely white- velvety 

 on the under surface; the 

 stout leaf-stalks are 5 to 20 

 mm. long. The hght blue 

 flowers are in rather dense white-velvety clusters at the ends of twigs and open 

 from January to April. The fruit is black, 7 to 8 mm. thick. 



The wood, which has a specific gravity of about 0.78, is hard, dense and 

 reddish brown. The species has been confused with the widely distributed 

 Ceanothus vdutinus, which it resembles.
