very juicy and sweet. It is cultivated throughout the 
central portion of Yunnan south of Menghwa, and also 
near Puerhfu in southern Yunnan; it is grown at an 
altitude of 5,000 to 6,000 feet and even higher. The

Salpiehroa rhomboidea (Solanaceae) ,55478. From Buenos 
Aires, Argentina. Seeds presented by Sr. Benito Car- 
rasco, director, Botanic Garden. Introduced for use 
in tomato-breeding experiments. 
An ornamental relative of the tomato, with white 
flowers and edible, white, transparent berries which 
resemble the pineapple in flavor. Because of its at- 
tractive appearance and creeping habit it is very ef- 
fective for covering bare places. (Adapted from The 
Garden, vol. 35, p. 367.) 
Severinia buxifolia (Rutaceae ) , 55495 . From Bui tenzorg, 
Java. Seeds presented by the director , Bo tanic Garden. 
A much-branched , thorny shrub which is not uncommon in 
southern China and French Indo-China; it has oval, 
shiny green leaves, axillary clusters of small white 
flowers, and small berrylike fruits which become very 
dark red. or nearly black. In Louisiana this handsome 
shrub has proved useful for hedges, especially the 
forms which have thorns 2 or 3 inches long; further- 
more, it is easily propagated from cuttings. Experi- 
ments have shown that Severinia can withstand unusual- 
ly large amounts of salt in the soil, and it may prove 
of interest as a stock for citrous fruits in regions 
having alkali in the soil or salty irrigation water.
