CASUARINACEAE. 

 CASUARINA, Linn.

Cultivated in the Campo Santo of Dolores, Island of Mugeres; 

 Streets of San Miguel, Island of Cozumel; Island of Cankun; 

 and in Merida, Izamal, and Progreso, Jan. 26, 1895 (204), height

MORACEAE. 

 FICUS, Linn. 



F. laurifolia, Lam. Laurel de la India. 



Cultivated extensively as an ornamental shade tree. Intro- 

 duced from Cuba. Fine examples at Oncaan, Ouan, and Bocoba. 



F. rubiginosa, ? (Plate I, Frontispiece). Copo. Alamo. 



This form, to which we make doubtful reference in the ab- 

 sence of satisfactory flowers and fruits, is the most common 

 species throughout the route we traveled on the Peninsula. It is 

 a large tree 25 to 45 feet high, greatly spreading and very um- 

 brageous. For some unaccountable reason it is called the Alamo 

 (Poplar) by the Spaniards. Its juice contains sufficient caoutchouc 

 to form, when mixed with that of the Sapote, an excellent bird 

 lime. 



F. grandifolia, ? AKUM. 



A large tree 30 to 50 feet high. Fine specimens noted at 

 Chichen Itza. 



ALICASTRUM, P. Br. 



A. Brownei, O. K. Ramon. OX. 



Brosimum Alicastrum, Sw. Cultivated for fodder throughout 

 the region embraced, also on the Islands of Mugeres and 

 Cozumel. Fine specimens at Merida, Izamal, and Chichen Itza. 

 Grows from 50 to. 80 feet high. Yucatan, loc. ignot. (Linden). 



The foliage " Ramon," serves as the principal green fodder for 

 horses and mules from June to March. The wood is white and 

 compact, and is used in carpentry; the fruit when boiled is eaten 

 either alone or mixed with honey or corn meal, and the milky 

 juice is used as an anti-spasmodic in the difficult breathing of 

 asthma. 



URTICACEAE. 



URERA, Gaud. 

 U. microcarpa, Wedd. 



Yucatan, loc. ignot. (Johnson).
