From Monte, Grand Canary, Canary Islands. Presented by Mr. Alaricus 

 Delmard. Received December 2, 1907. 



" Seeds of a species of low-growing shrub which grows on the slopes of the 

 arid hillsides in the Canary Islands. It has a most beautiful weeping habit, 

 giving the plants the appearance of tiny weeping willows, not over 2J to 3 

 feet high. This would be very beautiful as a cover for dry hillsides overlook- 

 ing the sea. It has already been brought into culture. Will probably with- 

 stand severe drought." (Fairchild.)

From Pasadena, Cal. Presented by Mr. J. B. Wagner. Received Decem- 

 ber 4, 1907. 



" Wagner's Giant Hybrid. This is a cross between Eastern Black and Santa 

 Barbara Soft Shell. It is now about 20 inches in diameter — 6 years from 

 seed — while neither of its parents at same age, grown within 50 feet of it 

 under same conditions, is over 5 inches in diameter. This, I believe, and Bur- 

 bank says, is the most rapid growing hardwood tree in existence and a boon 

 as wood and lumber." (Wagner.) (See also Nos. 19261 and 21710.)
