GENERAL NOTES. 
This locality is about 20 miles south of Alvarado on the Rio 
Cosamoloapam, a few miles above the Bay of Alvarado* The situation 
is low, being on a broad alluvial plain, over much of which the water 
extends during the summer rains. The river is affected by the tides 
from the Gulf for some distance above the town. The level plain is 
unbroken for miles, and is dotted with ponds and marshy places. 
VEGETATION . 
There are many open grassy areas or llanos, usually containing 
ponds or marshy spots where there are many plants peculiar to such 
localities. Along the banks of the small streams also grow many such 
plants. Most of the plain, however, is overgrown with scrubby trees 
and thickets of low brush. The trees rarely exceed 30 feet in height 
and are scattered among brushy growths of from 6 to 10 feet. The 
overflow of brackish water here during summer probably prevents the 
trees common higher up the river from growing here. Palms are also 
very scarce in the lowlands. The plants sent in from here, numbering 
from 488-530, give an idea of the flowering species here at this 
season. Sugar cane is the main crop grown here.
