tal and also provide countless berries for the birds. 
The seeds do not digest and I find young plants coming 
up all through my grove . The plant appears to be rather 
hardy and endured a sharp frost a few years ago."

Lycopersicon eseulentum (Solanaceae) , 52334. Tomato. 
"Harrison ' s Prolific . " From Burringbar ,New South Wales . 
"The packet of seeds which you sent me I planted at 
once, and am sending you today a sample basket of the 
tomatoes. They have but little acid, are smooth and of 
uniform size, and when ripe are a rich purpie-red. The 
plants are drought-resistant . I am delighted with this 
variety and would like to plant an acre if possible."

Ulmus densa (Ulmaceae) , 32829. Elm. From Merv, Tur- 
kestan. "Since planting the two trees which you sent me 
we have had two unusually severe winters. The trees have 
made a rather remarkable growth; they are now about 25 
feet high, and increase about 5 feet in height each 
season. The foliage is rather dense and of a healthy 
green, the leaves are very small, and the branches 
have a drooping habit somewhat like that of the weep- 
ing willow. The tree is absolutely free from any dis- 
eases or insect pests, and I consider .it one of the 
most valuable introductions made for many years. It 
grows very rapidly, even more so than the poplars." 
(W. S. Pilling, Philadelphia, Pa., June 2, 1922.) 
Zephyranthes sp. (Amaryllidaceae ) , 43053. From Co- 
lombia. "This may make a very good bedding plant, as it 
increases very rapidly and stays in bloom for weeks." 
(Frank W. Campbell, Detroit, Mich., May 16, 1922.) 
Ziziphus jujuba (Rhamnaceae ) , 22694, From Shansi, 
China, and 37475, from Honan, China. Jujube. "These are 
both doing very well and producing splendid fruit . The 
trees do not come into leaf until late, so there is 
never any loss by late frosts. I am sure that the ju- 
jube will be planted extensively in Arizona, for it is 
a fine looking tree and bears well." (Geo. W. P. Hunt, 
Phoenix, Ariz., May 16, 1922.)
