MELINIS MINUTIFLORA. (Poaceae.) 29100. Seed from Brazil. Pre- 
sented by Dr. Orville A. Derby, Service- G-eologico e Mineralogico 
do Brazil. "The species of grass named Panicum melinis (Melinis 
minutiflora) occurs in at least two distinct varieties: capim 
catingueiro roxo and catingueiro claro. The Melinis minutiflora 
is certainly but a synonym of the Panicum melinis and no distinct 
species. A variety has been found at Petropolis, but as I had nc 
opportunity to see this variety I think it is an adaptation to 
the different conditions of humidity in the mountains." (Albertc 
Lofgren, Director, Botanical garden, Sao Paulo, Brazil.) For 
distribution later.

Seff er.) For distribution later.

Turkestan, near Irkestan. "A poplar found here and there in 
clumps on sandy flats and on alkaline places. Leaves round, el^ 
liptical, color of trunk and twigs gray-white. The trees do not

"The wood of this tree is used almost exclusively in the match-
