nodes measuring from the base upward: 11.5, 7.6, 9.3, 35.7 
mm. respectively. The fifth internode was missing but a shred 
of its rind still remained and measured 79.5 mm. showing that 
the ear must have been borne on a long peduncle within the 
husk. This husk system with its fifth internode restored and 
terminated by the longest cob from the same level is shown 
diagramatically in Fig. 4. One of its noteworthy features is the 
scar of a branch on the second internode. Apparently husk 
systems of this type enclosed not a single ear but several, in this 
case probably two. A similar husk system from level | had the 
shred of a peduncle measuring 48 mm. in length. The original 
peduncle may have been considerably longer. 
There is a tendency in these prehistoric husk systems for the 
two outer husks to be somewhat differentiated from the re- 
maining inner ones in the thickness of the tissues. This is also 
true in modern varieties but the differentiation is by no means 
sharp, the transition from the outermost to the innermost being 
a gradual one. In the prehistoric husk systems the two outer 
husks are definitely thicker than the remaining inner ones 
which are almost tissue-paper like in their texture. 
The husk system showing the differences between the outer 
and inner husks is illustrated in Plate 48B. 
TASSELS, SPIKELETS, ANTHERS, AND POLLEN: Two almost 
complete tassels and 12 fragments were found. A diagram of 
one complete tassel is shown in Fig. 5. The tassels are similar to 
those of the Peruvian popcorn Confite Morocho (Grobman et 
al., 1961, Fig. 50) in the number of tassel branches and their 
arrangement. (Plate 50). 
The staminate spikelets of the prehistoric specimens are like 
those of modern maize, arranged in pairs, one member of each 
pair sessile the other pedicellate. Their glumes which are more 
rounded and less strongly keeled than those of many modern 
varieties, are beset with short hairs as are also the stems of the 
tassel branches. Spikelets from three tassel fragments in Level 
4 had average glume lengths of 7.8 mm., from two tassels in 
Level 2, average lengths of 8.8 mm., and from 9 tassels in Level 
1, average lengths of 7.5 mm. Although there is no evidence of 
an evolutionary series in the spikelets from these three levels,
