portion of the cup is greatly contracted into a narrow, flattish ring, 
overlying the disk, and is there furnished inside with numerous erect, 
very short, staminiferous gered an en if assumes a ver 
notable expansion on one s y; where it is called the ligula, in 
the form of a fleshy, frost, apourring naps biat of appendages, se 
then becomes further expanded in into a concave hood, inverted o 
he disk, and densely echinated inside vith long appendages, like 
those of Gustavia, all incurving in many series, and converging over

of stamens. Such of the andro Nee n in Couroupita, 
Bertha Lecythis, Dealionts rs sari ane rum, Couratari, 
and Allantoma ; but in Cere vr ee the hood is po uch-shaped and quite 
bare of appendages. The inferior ovary is 4—6-celled in Gustavia, 
Couroupita, Bertholietia, yp and Chytroma ; 3-celled in : Comnaaa 
Cariniana, and Allantoma ; and only 2-celled in Lschweilera and Jugas- 
m. The fruit is cmuenily large, often very large, thick, and woody, 
opening by a deciduous operculum, which is an expansion of the 
vertex of the ovary, the main body of which grows into a large, ovate, 
turbinate, or cylin pyxidium, and about the middle or above it 
a line ca cal zone, formed by the vestiges of 
the limb of the calyx, sometimes enlarged into conspicuous 8 
Above this, and below the opercular zone, is a br omewhat erect

softening of the dissepiment and placentz, as in aioe Couroupita, 
and Lecythis; it is void of pulp in the other The seeds, often 
are § b hy doe as large as them-

niana the seeds have a_ broad eer paigtioy wing, surrounding @ 
small embryoniferous scutcheon, and are t, fixed near the bottom 
of a large hard columella. In Allantoma fie are long, narrow, com- 
pressed, rugous, erectly fixed in a similar manner. The embryo in 
all cases is without album men, In Gustavia it consists of two plano-

and very bitter, all equally macropodous or of one homogeneous tex- 
ture. In these macropodous embryos we recognise a gigantic radicle, 
consisting of two portions, agglutinated tégether, one enveloping the
