abundant as P. tremula. P. tremula does not appear to have 
"been noticed by "botanists in America although it is frequently 
found planted in our parks. It is readily recognized by its 
large, 1 cm., long and one half as wide, dark-brown buds. These 
are rather blunt and not pointed as in the case of the Lombardy 
and Carolina poplars. Populus tremula was in all probability 
introduced into Maryland by the early settlers, as it and other 
species are frequently found about the old mansions. w (Mr. I.

for match wood production.) For distribution later. 
BAJANIA PLEIONEURA. (?) (Dioscoreaceae . ) 29129. Tuber of "Waw- 
waw". Presented by Mr. Robert M. Grey, Superintendent, Harvard 
Botanical Experiment Station, Cienfuegos, Cuba. n A large tuber 
that was brought in by one of the Guajiros from the hills under 
the name of 'Guagua name', but I did not see the stem or fol- 
iage so am not sure that it is Rajania pleioneura, which is 
also known here under the name of ' Alambrillo 1 . " (Grey.) For 
distribution later. 
REAUFUREA SP. (?) ( Tamaricaceae . ) 29147. Cuttings from Chinese 
Turkestan, near Irkestan. "A tamarix-like shrub found on very

northern parts of the United States. Pound at elevations of 
8,000 feet and less." (Meyer's introduction.) For distribu-

cold, stony canon at an elevation of over 9,000 feet above sea. 
A very palatable preserve can be made from the ripe berries, as 
the Russians do who live here and there in the mountains. This 
shrub may be of value as a garden fruit in the most northern 
sections of the United States." (Meyer's introduction.) For 
distribution later. 
RIBES RUBRUM. (Grossulariaeeae.) 29141. Cuttings from near 
Guldscha, Russian Turkestan. "Red currant found growing on a 
dry mountain side at an elevation of about 6,000 feet. Of vig-

hybridization experiments and, when somewhat improved as a 
hardy garden fruit, for the northern sections of the United 
States." (Meyer's introduction.) Por distribution later.
