55893. RUBUS sp. Raspberry. "(August, 1922.) A shrub growing 
in sheltered ravines on the Likiang snow range at an altitude of 11,000 
to 12,000 feet. It has crimson-stemmed drooping branches and trif olio- 
late leaves with the lower surfaces slightly pruinose or silvery. The 
fruits, somewhat smaller than those of the preceding species, are ob- 
conical, darker red, and faintly pubescent." 
55903. RUBUS sp. Raspberry. "(No. 5834. August 16, 1922.) A rasp- 
berry with large, rich green leaflets, collected on the Likiang snow 
range at an altitude of 11,000 feet. The yellow fruits, the size of a 
thimble, have a delicious flavor. The plant thrives in limestone soil." 
55904. RUBUS sp. "(No. 6057. August 24, 1922.) One of the fin- 
est species of Rubus on the Likiang snow range, where it grows at an 
altitude of 13,000 feet in forests of Larix thibetka. The orange-yellow 
fruits are larger than any of the cultivated species of Rubus, and are 
rich in color, juice, and flavor." 
RUBUS fraxinifouus (Rosaceae), 55833. From Buitenzorg, Java. 
Seeds presented by Carl Hartley. "A Rubus collected at an altitude 
of about 3,500 feet on the Salak in West Java. The bush is often 2 
meters high, and very slightly thorny. The conical strawberry- red 
fruit, 2.5 centimeters long and 2 centimeters wide at the base, is 
inclined to be hollow and deficient in pulp, but it is not acid and 
the flavor is fairly good. The species may prove valuable in breeding 
work." (Hartley. ) 
Behavior of Some Plant Immigrants. 
Beverly T. Calloway. 
Many plant immigrants reach the Office of Foreign Seed and Plant 
Introduction with little information as to what they are, what may be 
expected of them, or where they should be placed to bring out charac- 
teristics which may determine their value to American agriculture or 
horticulture. This, after all, is one of the charms of plant intro- 
duction work. Potential possibilities and values lie hidden in all 
little-known plant immigrants. To discover these and make them redound 
in some way to the benefit of our people is the aim of the plant in- 
troducer. From time to time we can report progress on some of the 
things brought in. This may give us a new starting point and be the 
means of broadening the field of knowledge so that other workers may 
profit therefrom. 
malus sylvestris (Malaceae), S.P.I. No. 35638. Apple. In December, 
1912, the late Frank N. Meyer, while traveling in southern Russia, se- 
cured through Svend Lange at Novo Nikolayefsk, two small lots of
