soon as its value became known to tanners. It would be 
especially valuable for fancy leathers." (Shantz.) 
QuUlajo braziliensis (Rosaceae), 48686. Quillay or jabon 
de palo. From Montevideo, Uruguay. Seeds presented by 
Sr. Luis Guillot, Direccion General de Paseos Publi- 
cos. A- Brazilian tree, 6 to 8 meters high, with an 
erect trunk and an open crown. The alternate leaves 
are oblong-lanceolate and the white flowers are in 
distinct corymbs. The fruit is formed by five capsules 
in radiating arrangement, with numerous compressed 
and winged seeds. The regular shape and very leafy 
crown make it a striking ornamental, especially when 
it is in flower. The bark and wood cut into chips 
form articles of commerce, from which are extracted 
salt and mucilage constituents which are used in the 
saponification of greasy substances. (Adapted from 
Arechavaleta, Flora Uruguaya, vol. 1, p. 451.) 
Rubus sp. (Rosaceae), 48751-52. Blackberry. From 
Bogota, Colombia. Seeds and plants purchased from Mr. 
F. L. Rockwood. "This berry is not in clusters like 
the common berry, but on the end of a branch like a 
rose. There are always several together; they bring 
the bush down with weight. Some of the berries are 
over two incbes long when ripe. One berry, which 
measured two and one-half inches, dropped to pieces 
while we were bringing it out of the forest. These 
berries are developed where there is constant mois- 
ture, clouds against the mountains, and a temperature 
of 65°F. to 68°F. They grow in abundance near Purifi- 
cation, Tolima, where they are pressed for a juice 
which is claimed to have medicinal properties for cur- 
ing blood diseases. The line of mountains from Cibate 
to Fusagusaga, about 9,000 feet elevation, is very 
prolific in blackberry plants; these do not grow above 
the coffee line." (Rockwood.) 
Notes on Behavior of Previous Introductions , 
A letter received January 14, 1920, from Mr. 
Herman Schrader, Berryville, Ark., contains the fol- 
lowing: "I have been very successful with the plants 
received from your Office. The Chinese dwarf lemon, 
Citrus Hmonh, S. P. I. No. 23028, bore 6 large fruits; 
one of these made 2 pies. I keep the plants in my 
greenhouse in the winter and set trie pots outdoors in 
the summer. Many people come to see these lemons."
