The common eight-rowed pop seems to have no history, al- 
"though probably in cultivation in New England from early times. 
It belongs to sub-species A. The plants frequently bear several 
cars to a stalk and are subject to monstrous growth. The twelve- 
rowed, a representative of sub-species B, also seems to have no 
history. Under the name of small white, Salisbury, 1848, says it 
bears from three to seven ears to a stalk. A lemon-yellow form 
isthe milho pepoca, of Brazil. Sub-species C has the largest rep- 
resentation. It comprises the mais quarantino of France, at least in 
the samples I have received, and the mais nain, mais a poulet of 
the French ; the cinquanto, sessantino and torquetto of Italy, 
Probably. In Mexico, under mais cuarentano, Heller gives Mexi- 
‘an names of varieties as mais tremes and olote colorado. The 
golden pop group are distinguished by small size of ear and kernel 
and extreme earliness. Hence we may mention here, without 
certainty as to the species, early maturing varieties. Humboldt 
quotes Oviedo as having seen in Nicarauga a variety ripening in 
3° or 40 days, says that he remembers finding this variety on the 
banks of the Amazon, and that in Hungary there isa two months’ 
"Variety, Dalechamp, 1587, refers to a variety that matures in 
two months, and another less grown which ripens in 40 days. 
Porta, in his Villa, 1592, refers to a six weeks’ and two months’ 
corn. Lery, in his Brazil, 1 594, namesa 45 daycorn. Morison, 1699, 
describes from America the “Rathripe’”’ corn. Dobrezhoffer, 1749, 
mentions in Paraguay, the abati miri, which ripens in a month, but 
has very small dwarfish grains. Catlin describes finding among the 2 
andan Indians an early corn with ears as long as a man’s thumb. 
Nuttall calls this Zea Mays precox,a name which Bonafous repeats 
lor a golden pop variety. “The corn of Lake Titicaca, described by 
Squier as dwarf and hard grained, is almost certainly apop. The 
8olden pop varieties when grown in pots usually develop tassel 
orn in my experience. Hence we note here that Parkinson, 
1640, describes the Frumentum indicum alterum minus, as grown 
the unfavoring English climate, as not bearing crop “at the 
: Joynts of the Stalkes as the other, but at the toppes following the 
OWers.” This variety was not known to Ray, 1688, and che 
a doubts the description and classes with Frumentum indicum ee s 
- dictum minus, C. Bauhin, 1623. The pearl pop group is distin-
