Pyrus ussuriensis Maximowicz. (Malaceae.) 45046. 
Pear. Prom Charles City, Iowa. Presented by Mr.. Charles 
G. Patten. The origin of these cuttings is given in 
the following account: "In the reports of the Iowa 
Horticultural Society for 1906 and 1912, Mr. Charles 
G. Patten called attention to a Chinese Sand Pear which 
he has used in some of his breeding work. He states 
that in 1880 Mr. 0. A. Bardhall, of Grundy Center, 
Iowa, purchased a tree of the Chinese Sand Pear from 
John S. Collins & Sons, of New Jersey, which they 
represented would bear fruit nearly as large as the 
Flemish Beauty. When It came into bearing the fruit 
proved small, hard and worthless. Mr. Patten propa- 
gated a tree from this because It had proved Its great 
hardiness during the severe Iowa winter of 1883-84. 
Mr. Patten states that his tree at Charles City, Iowa, 
has never been injured in the least by cold and has 
never blighted since it was . planted in 1885. Since 
Pyrus U88urieri8i8 has proved so remarkably resistant to 
blight in our work, and as it is the hardiest species 
of pear known, I thought that possibly Mr. Patten's 
tree belonged to this species. In reply to a letter 
Mr. Patten kindly sent me leaves of his tree which I 
received on November 10 of this year. As the tree had s 
not borne this year.no fruit was sent, but Mr. Patten 
kindly furnished a description of the fruit and stated 
that the tree probably belonged to Pyrus sinensis. An ex- 
amination of the leaves, however, shows conclusively 
that this tree belongs to Pyrus ussuriensis. The tree in 
Iowa is the oldest one of this species in America so 
far as I have been able to learn. Undoubtedly there 
are other trees in America just as old or older than 
the Iowa tree. It is quite probable that Collins & 
Sons sent out trees of this species other than the 
one sent to Iowa. I hope that some of these can be 
located and the writer would be pleased to receive 
specimen leaves and fruits of any tree which promises 
to belong to this species." (Reimer, Blight Resistance 
in Pear Trees and Stocks.) 
Triehilia eatigua A. Jussieu. (Meliaceae.) 45069. 
Katigua seeds from Puerto Bertoni, Paraguay. Present 
ed by Dr. Molses S. Bertoni. "(June, 1917.) Katigua. A 
small ornamental tree, found throughout the forests 
of Paraguay. The bark, according to our analyses, 
contains 20.5 per cent crude tannin, and a large pro- 
portion of coloring matter for dyeing. The leather 
thus tanned is of a red color which is much esteemed."
