A. A cluster of teosinte spikes with a number of the fruits exposed to view. These, like the fruits 
of modern Mexican teosinte, are triangular in shape and in this respect differ from the fruits of 
Guatemalan teosinte which are trapzoidal. B. A spike identified as that of a maize-teosinte hy- 
brid. This differs from spikes of teosinte in having a solid rachis and herbaceous, instead of in- 
durated, lower glumes. Note that the stalk on which it is borne is thicker than the stalks of teosinte 
shown in Plate XII, A. Actual size.
