This is described by Gardner in his travels (/oc. cit.) as a tree growing у 
and abundantly in the province of Ceará, where it is known by the name of Pdo branco 
(white wood) ; it grows to heights of from 20 to 40 feet, its wood, not very hard, being ex- 
tensively used by the natives for fuel. The branchlets are 2 lines thick, with axils 1-11 in. 
apart; the leaves are 5-63 in. long, g; 
panicle is about 3 in. long and broad, 5 or 6 times dichotomously divided; the ultimate 
divisions are very slender, 3 in. long, bearing on one side about 8 or 10 nodules where 
the sessile flowers were attached; but in the dried specimen only a single flower remains 
upon the spikelets; the calyx is 2 lines long, 11 line broad; the tube of the corolla 2 
lines long, the lobes of the border 2 lines long, 1 line broad; the filaments 3 line, the 
ovary $ line long, the style of the same length. In fruit the enlarged calyx is 21 in. 
long, 1$ in. broad, membranaceous and reticulated, with 5 acute angles, terminating 
below in 5 large hollow sacs which extend half an inch below the summit of the thick- 
ened spikelet, tapering upwards to a width of 4 lines, and terminated by 5 erect teeth; 
the drupe, fixed on the point of atjachment, is 2 in. long, 8 lines broad; the sarcocarp 
thick, soft, and spongious, enclosing an osseous oe with an uneven surface, with a hollow 
space below, filled with medullary matter; above, it has four cells, two of which are 
smaller, but all four contain each a single erect seed ; in the base of each cell a foramen is 
‚ seen for the passage of the nourishing vessels to the basal chalaza of the seed, which is 
nearly 3 lines long ; its two integuments are white, very thin, and brittle, marked at the 
pointed summit by the mieropyle; there is no trace of a raphe or other spiral vessels.
