name, and it is accordingly proposed to call it the Telfair citrangequat 
(PI. 2, C). 
Another citrangequat of the same parentage is C. P. B. No. 48007, 
which was conspicuous for its extreme vigor when young. (PI. 1.) The 
fruit, like that of the Thomasville, acquires something of an orange flavor 
as it ripens. It seems to be an early ripening variety. The peel is mild 
flavored, and the seeds are few. 
Still another citrangequat is C. P. B. No. 48050, a hybrid of the oval 
kumquat with the Rusk citrange. It attracted the attention of Mr. J. 
W. Benson, a cooperator living at Sinton, San Patricio County, Tex., 
near Corpus Christi, by its superior cold resistance and nearly seedless 
fruits. A tree that flowered in October, 1918, carried a crop through 
the winter unharmed. Samples received at Washington on April 23, 
1919, were very like a lime in appearance and flavor, but showed a small, 
fleshy calyx, somewhat like that of the Rusk citrange parent. Fruits 
of this number, received November 1, 1920, from Glen St. Mary, Fla., 
were strikingly handsome, being bright orange or even flame scarlet in 
color. They were from to 1%, inches in diameter, nearly spherical, 
and had few or no seeds. These fruits were overripe, but the pulp was 
still acid, so this is doubtless an early maturing variety suitable only 
for ade. 
As this citrangequat has attracted attention, not only because of its 
nearly seedless lime-like fruits produced in Texas, but also because of 
the extraordinarily brilliant color of the fully ripe fruits in Florida, it 
seems best to give it a name. It is accordingly called the Sinton 
citrangequat. 9 10 
EUSTIS LIMEQUAT 
In 1909, the senior author originated a new type of citrous fruits by 
crossing the West Indian lime with the kumquat oranges. Those familiar 
with citrous fruits know that the lime is the tenderest of all the commonly 
grown species of this group. It frequently freezes to the ground even 
in southern Florida, so that its culture is chiefly confined to the fringe 
of keys along the coast. The kumquat, on the other hand, is one of the 
hardiest of the evergreen citrous fruit trees. This is without doubt not 
so much due to its direct powers of cold resistance as to its remarkable 
dormancy. The kumquat, as noted above, is able to pass unaffected 
through long spells of hot weather that force other Citrus trees into a 
tender and succulent growth that is liable to be injured by even a light 
9 Technical description of the telfair citrangequat: Fruit spherical (sometimes slightly flattened 
or elongated) mature fruits having a diameter of inches to i54 inches; calyx persistent with 5 long points; 
color of mature fruit light orange yellow to deep chrome (Ridgway, Robert, op. cit., pi. Ill, 17. b, d); rind 
thin, somewhat roughened; oil cells prominent, small, numerous; core little or none; segments 4 to 6 (usually 
5), seeds few, variable in size, usually undeveloped, pulp pale yellow; Pinard yellow, (Ridgway, Robert, 
op. cit., pi. IV, 21, d.), sharply acid, and retaining this quality when mature; rind slightly bitter; tree ever¬ 
green, vigorous, of upright habit; leaves uni-, bi-, and trifoliate, generally obovate, iM to 254 inches in length, 
finely serrated; plant fairly thorny, thorns smaller in size on the fruiting twigs; bloom often occurring over 
a long period, giving a semieverbearing fruiting habit. 
10 Technical description of the sinton citrangequat: Fruits varying from slightly flattened to slightly 
elongated; growing in clusters; diameter varying from i54 inches to i 7 A inches; calyx small, persistent, 
slightly protruding, sunken pistil surrounded by a very small raised circle; color variable, ranging from a 
light orange-yellow (Ridgway, Robert, op. cit., pi. Ill, 17, d), to a light flame scarlet (Ridgway, Robert, op. 
cit., pi. II, 9); rind very thin, smooth, highly colored, iV inch in thickness and much like kumquat, show¬ 
ing almost none of the flavor of the trifoliate orange; oil cells few, variable in number; segments 7 to 8; no 
seed in 100 of fruits, occasionally one or a few; pulp pale, varying from orange-buff (Ridgway, Robert, op. 
cit. , pi. Ill, 15, d), to a light cadmium (Ridgway, Robert, op. cit. , pi. IV, 19); flavor sharply add, deddedly 
lime-like with only faint suggestion of dtrange flavor given by the oil from the rind, no dtrange flavor in 
the juice; makes a good ade; core very small and segment walls very thin; tree much more hardy than the 
lime; bearing twigs spineless; leaves on bearing branches unifoliate, rather thin, 2 to 3 inches in length by 
1 H inches in width; petiole 54 inch long, slightly winged; midrib heavy, prominent on upper surface; leaves 
tapering slightly toward the apex.
