of difficult parturition. The ergot of Maize is, according to Roulin, very 
common in Colombia, and the use of it is attended with a shedding of the 
hair, and even the teeth, of both man and beast. Mules fed on it lose their 
hoofs, and fowls lay eggs without shell. Its action upon the uterus is as 
powerful as that of Rye ergot, or perhaps more so. Ann. des Sc. 19. 279. 
The country name of the Maize thus affected is Mai's peladero. The best fod- 
der Grasses of Europe are usually dwarf species, or at least such as do not 
rise more than 3 or 4 feet above the ground, and of these the larger kinds are 
apt to become hard and wiry ; the most esteemed are Lolium perenne, Phleum, 
and Festuca pratensis, Cynosurus cristatus, and various species of Poa and 
dwarf Festuca, to which should be added Anthoxanthum odoratum for its fra- 
grance. But the fodder Grasses of Brazil are of a far more gigantic stature, 
and perfectly tender and dehcate. We learn from Nees von Esenbeck, that 
the Caapim de Angola of Brazil, Panicum spectabile, grows 6 or 7 feet high : 
while other equally gigantic species constitute the field crops on the banks of 
the Amazons. 
I am deeply indebted to Professor C, G. Nees v. Esenbeck for the follow- 
ing fist of the Genera of Grasses, Dec. 12, 1835 : —
