Prunus bokhariensis Royle. (Amygdalaceae . ) 43039- 
43048. Seeds of ten varieties of plums from Saharan- 
pur, India. Presented by Mr. A. C. Hartless, Super- 
intendent, Government Botanic Gardens. 
Rubia tinetorum L. (Rubiaceae.) 43037. Seed from 
Paris, France. Procured from Vilmorin- Andrieux & 
Company. "The root of Rubia tinetorum furnishes dyer's 
madder. The plant is a native of the south of Europe, 
and is extensively cultivated about Avignon and in 
Alsace for the roots, which afford the fine scarlet 
dye so highly valued by dyers and calico printers. A 
great quantity is grown in the Levant, the north of 
Africa, and in Holland; but that from Africa and the 
East, particularly that from Cyprus, is the most 
esteemed. Several attempts have been made to culti- 
vate it in England, but without profitable success. 
The roots are dug up the third summer after sowing, 
and having been deprived of their cuticle, are dried 
by artificial heat, and then reduced to a powder. 
Madder has a bitter, astringent taste, and imparts 
these properties to water and alcohol." (Hogg's Vege- 
table Kingdom, p. 415.) 
Ulmus densa Lit vino v. (Ulmaceae.) 43031. Seed from 
Kieff, Russia. Purchased from Messrs. St. Przedpelski 
& T. Antoniewlcz. "An elm of most remarkable dense 
growth, sprouting out a little distance above the 
ground, into a number of stems, which form an umbrella- 
like head of foliage, which is so dense that it re- 
mains always twilight even at bright noon, in an ave- 
nue of these trees. This elm loves, apparently, a 
climate with long hot summers and with winters not 
too cold. Withstands a fair amount of alkali in the 
soil and in the irrigation water, and will prove of 
special value as a shade tree In the hot and dry In- 
terior valleys of California, Arizona, Texas and New 
Mexico." (Frank N. Meyer.)

"Your letter of Sept. 19th asks for information 
concerning the yellow flowered species and varieties 
of alfalfa, which we are growing at our interior 
stations, and which were presumably introduced by Pro- 
fessor Hansen, on his several collection trips.
