A NEW KIND OF GREENS FROM TROPICAL AFRICA. 
(Rumex abyssinicus Jacq., S. P. I. No. 48023.) 
As a source of greens during the hot summer months, the Abyssinian Rumex is of great promise. 
Seeds may be sown in the greenhouse or hotbed in early spring and the plants set out as soon 
as the soil can be worked. The plants grow 7 or 8 feet in height and continue to yield 
greens until cut down by frost in late autumn. The leaves are cooked and served in the 
same manner as spinach, but care must be taken to change the water, in cooking, to elimi- 
nate excessive acidity. (Photographed by Peter Bisset at the Yarrow Plant-Introduction 
Garden, Rockville, Md., October 31, 1919; P25595FS.)
