develop upon their surface, in more or less definite rows, numerous 
small waxy-yellow or red pustules which become pulverulent 
and somewhat elongated and have the general appearance of 
lenticels. The surface of the fruit shows more or less distinctly

the ten original longitudinal ridges of the ovary surface, but 
there are also an equal number, or more, of secondary ridges, 
so that the surface of the fruit in its final mature state is quite 
irregularly many-ridged and -grooved (Fic. 23). The wall of the 
fruit, which is indehiscent, is leathery and averages about one 
fourth of an inch thick. The single seed consists almost wholly 
of the large embryo, the seed- coats being scarcely recognizable 
and endosperm evidently lacking. The embryo is cordat 
general contour, with a rigid, pointed hypocotyl or radicle about 
half an inch long, which projects into the beak of the fruit
