Williams No. 146, ‘‘a tree 14 inches in diameter and 35 ft. high, 
with thin milky juice, Apolo, 4800 ft., April 16, 1902,” is probably 
the same, though its leaves are twice as large and its fruit a half 
larger. The latter wants the peculiar bracts upon the summit, 
though these may have fallen off. 
No. 420, “‘a slender bush, the fruit striped and spotted with 
urple, Tumupasa, 2500 ft., Jan. 4, 1902,” may be the same, but 
is probably distinct. Its leaves are relatively narrower, and are 
thin and inclined to be slightly broadened upward. It bears 
stipules 14 mm. long, tapering finely from the base. Its fruit is 
similar to that of No. 413. It is the same as Tonduz No. 11,576 
and very near Spruce No. 2217, which is called U. leucosticta Mig.
