A much-branched tree 20 feet or more high, with a flexuous trunk sup-

 marginal spines. (Adapted from Bailey, Standard Cyclopedia of Horti-

44781. "(No. 117. Avocado No. 29. From the finca Santa Rosa, An- 

 tigua.) Katun. A small, handsome avocado from the finca Santa 

 Rosa in Antigua, Guatemala (altitude 5,100 feet). The parent tree 

 ripened an excellent crop of fruit in the spring of 1917. A few fruits 

 of this variety which were examined had a slightly bitter taste. It 

 is not known whether this is a characteristic of the variety or not, but 

 it does not seem advisable to make a general distribution until this 

 point can be determined. 



" Technically the fruit may be described as follows : Form broadly 

 obovoid, oval, or oblong-oval ; size below medium to medium, weight 

 10 to 14 ounces, length 3i to 4 inches, breadth 3 to 3$ inches; base 

 rounded to bluntly pointed, the stem inserted somewhat obliquely with- 

 out depression ; apex obliquely flattened, though not markedly so, slightly 

 depressed around the stigmatic point ; surface nearly smooth to lightly 

 pebbled, glossy purplish black in color, with numerous small to large 

 yellowish dots; skin rather thin, one-sixteenth of an inch or slightly
