Panicum maximum. GUINEA GRASS. YERBA DE GUINEA. 
The guinea grass is said to have been used as bedding in the slave ships, and to 
have become established in tropical America accidentally after floating ashore 
from the rubbish thrown overboard when the ships were unloaded. The origin 
of this account should be traced as a note on plant introduction. 
Panicum molle. Para GRaAss. MALOJILLO. PLATE XLIX. 
As a pasture grass this species is second only to the Guinea or “‘yerba de 
Guinea.”’ Itis grown in the swampy meadows of the north coast and wherever 
the ground is too moist for the latter species. 
The Malojillo is deep green in color, decumbent at base, with very hairy joints. 
The flower stalk has fewer and shorter branches than the Guinea grass. Both 
species produce luxuriant crops, but both seem too coarse to represent the food 
value of the same amount of the temperate grasses.
