EXPLANATION OF THE ILLUSTRATION 
Prare LV. 1, A drawing of a pair of pistillate 
spikelets and their associated cupule in maize. The 
cupule has lignified wings(cw) and the outer glumes 
have membranaceous wings (gw). The ovary and 
even the young caryopsis is usually enclosed by 
floral bracts. The inspiration for this drawing came 
from an illustration of a single pistillate spikelet 
in Hackel (1887). About eight times natural size. 
2, Vertical and cross-sectional views of the pre- 
vious figure in order to facilitate labeling of parts. 
si, s2, spikelet—1, spikelet—2 ; /1, /2, lemma-—1, lem- 
ma-2; pl, p2, palea—1, palea—2; c, cupule. About 
four times natural size. 
3, A portion of a maize cob with spikelets re- 
moved. The cupules occur in several alternate lon- 
gitudinal rows. r, rachis; cw, cupule wing; rb, 
rachilla base. About three times natural size.
