resemble an orange, even to the external coloring, whence, in 
connection with its geographical range, the name ‘‘ Kaffir orange.” 
The fruits vary from three to four inches in diameter and weigh 
between one and two pounds each. However, the likeness to an 
orange ceases with the outside of the rind. This cannot be re- 
moved with the fingers or with a knife, as in the case of an orange, 
but a hammer or some similar instrument is needed to get at the 
pulp within the ‘‘Kaffir orange.’’ The rind is about an eighth 
of an inch in thickness, hard and somewhat brittle. Within, 
the fully ripe pulp is of different shades of red or pink. It is 
sweet, and in flavor it suggests that of a good canteloupe. Unlike 
an orange, too, the seeds of the ‘‘ Kaffir orange’”’ are poisonous, 
so that in eating the pulp in which the seeds are imbedded, great 
care must be exercised to eliminate all the seeds. The seeds 
closely resemble those of the related nux-vomica plant, and they 
are rendered especially easy to swallow by a slimy-hairy coat 
which envelopes each of them. 
The accompanying figure representing the two specimens of 
“Kaffir orange’’ received at the Garden through the kindness of 
Mr. Edward Simmonds, Gardener of the Subtropical Garden of 
the United States Department of Agriculture at Miami, Florida, 
is as far as we know the first illustration of this interesting edible 
fruit. The fruits as they appear in the figure are about three- 
fourths natural size.
