"Cuttings of a tree growing at the Villa Tluiret (but originally from Syria), 

 whitli is a rather rare but very interesting ornamental, being covered in the 

 spring with large white flowers, and in the autumn maturing fruits which make 

 excellent preserves. A Syrian friend of mine tells me that in his country this 

 tree is very popular." U'oh-ault.)

From Algiers, Algeria. Cuttings presented by Dr. L. Trabut. Received 

 March 9, 1921. 

 A tree native to Lower California, which grows to a height of 80 or 90 feet, 

 with a stout trunk 3 feet through, covered with rough ash-colored bark, and 

 with ascending branches. The silky pubescent and ovate leaves are 3 inches 

 long. The tree grows on the high mountains of the interior of the Cape region 

 of Lower California, and along streams which it often follows well down 

 toward the warm lowlands. The leaves and flowers appear in February; in 

 October all are fallen, an unusual condition in Lower California where most 

 of the vegetation comes forward with the summer and fall rains. The light 

 reddish wood of this tree is used for making furniture. The wood much 

 resembles cherry in color, is close grained, moderately- hard, and shows a 

 handsome satiny surface. It appears well suited for the interior linish of 

 houses or for the better classes of cabinetwork. It is therefore desirable that 

 this tree should be tested for timber in countries with a temperate climate. 

 Since it grows at a considerable elevation above the sea, where the temperature 

 sometimes falls below the freezing point, the tree might be ex-pected to thrive 

 in Southern California and in all the Mediterranean basin. (Adapted from 

 Garden and Forest, vol. Jf, p. 330.)
