nearly a quarter of an inch in diameter, dark chestnut-brown 
and lustrous, penetrated nearly to the apex by the broad basal 
cavity. : 
A tree with a slightly tapering stem from twenty to thirty 
feet in height and from four to six inches in diameter, covered 
with smooth pale blue-gray rind and generally clothed to the 
middle and occasionally to the ground with the persistent clasp- 
ing bases of the leaf-stalks. Leaves nearly orbicular, or truncate 
at the base, rather longer than they are broad, yellow-green and 
lustrous on the upper surface, silvery-white on the lower surface, 
divided to below the middle into numerous lobes varying from 
an inch to an inch and a half in width near the middle of the 
leaf; ligule long-pointed, bright orange color, three quarters of 
an inch long and broad; petioles from four feet to four feet 
and a half in length, pale yellow-green, three quarters of an inch 
wide at the orange-colored more or less tomentose apex, much 
thickened and tomentose and from two inches to two inches and 
a half wide at the base. Spadix from three feet to three feet six

Discovered by Dr. A. W. Chapman on Cape Romano in the 
autumn of 1875, and on Cape Sable by Dr. A. P. Garber in 
October 1879. This is the Thrinax excelsa of Florida nursery- 
men but not of Grisebach. Closely related probably to Thrinax 
parviflora of Swartz, which appears to be widely distributed 
through the West Indies and to occur on the shore of Central 
woe but distinct from that species, as collected by Charles 
ss ha in Cuba (xo. 2329) and determined by H. Wendland, in

Cavity, and pronounced unlike any of the species of
