guished by the dense aggregation of the kernels and their nacre- 
like lustre. Molina calls it the stone maize. Samples from Rio 
Claro, Brazil, were labeled milho perola. In California I have seen 
on exhibition stalks bearing up to nine ears. The Mapledale 
Prolific, which seems to belong here, is figured by a seedsman in 
1890, with sixteen ears on a stalk, some of the ears clustered 
two in an axil; an affidavit accompanying says that 10 stalks had 
121 ears, and one stalk 19 ears. The rice pops are peculiar for 
their pointed kernels, and the tendency to yield cone-form ears 
with imbricated kernels. They seem ancient in Peru, as having 
been found in sculpture. Rivers and Tschudi say that the rice 
pop kind and cone-shaped ears were considered as sacred things 
and were buried with mummies by the Peruvians. Dobrezhoffer, 
1749, says that in Paraguay the kind with pointed kernels was 
called bisingallo. A noticeable feature of the rice pop is the ten- 
dency to sport. Frequently half the ears of a garden crop will be 
flattened or digitate at their apex, and in the Bear’s Foot variety 
this tendency has become permanent to form a flat ear. There is 
also a tendency in the plant to form branches, or to bear aggfe- 
gate ears, or to develop tassel corn, and occasionally tassel ears. 
“The Monarch White Rice, as advertised in 1887, is figured as 
bearing tassel ears and also seven ears on a stalk. When grown 
separately the plants usually sucker greatly. The description of 
the kernels of Zea canina Wats. as “small, white, hard and 
smooth, ovate, acutish, constricted at base,” would apply t0 this 
class, but the “ears small, 4 to 12-rowed,” offer a variety not yet 
known to me. His other characters, except as to the spikelets 
and glumes which I have not looked for, do not differ from char- 
acters to be observed in all our species as of frequent OF aut a
