Deciduous, falling off. 
Discrete, separate, distinct, not confluent. 
Echinulate, covered with short sharp spines. 
Elliptical, having the form of an ellipse or oval with the ends rounded. 
Endochrome, the protoplasmic contents of spores or hyphe, usually 
applied to the coloured cell-contents of spores. 
Epiphyllous, growing on the upper surface of the leaves, 
Erumpent, bursting through the surface of the host-plant or matrix. 
Fimbriate, torn into a fringe. 
Foramen, a small hole or perforation. 
Germ-fore, the opening in the walls of a spore through which the 
germ-tube is protruded. 
Germ-tube, the tube emitted from a spore in germination, which may 
become a promycelium or may develop into a mycelium. 
Globose, spherical, the shape of a globe. 
Glomerulus, a small rownd head. 
Hlaustorium, a short lateral branch of a mycelial hypha, which enters 
a cell of the host-plant and acts the part of a sucker. 
Hleterecious. Those parasites which pass one part of their lives upon 
one host-plant, and the other part upon another of a different 
species, are said to be hetercecious. 
fTooded. Those spores which have a much thickened membrane at 
their upper ends are said to be hooded. Sometimes they are 
called capitate. 
fymenium, the base of an zcidial cup formed by those hyphz which 
produce the zecidiospores. : 
Hypha, a branch of mycelium, consisting of an elongated cell. 
fypogenous, Hypophyllous, growing on the lower side of the leaves. 
Intercellular, between the cells of the host-plant. 
Intracellular, inside the cells of the host-plant. 
Isodiametric, having the transverse, longitudinal, and perpendicular 
diameters the same length. 
Laciniate, cut or torn into segments or laciniee. 
Ligulate, tongue-shaped. 
Lumen, the calibre of a tube. 
Mesospore,a unicellular teleutospore occurring in a Puccinia spore-bed; 
a middle spore-form between Uromyces and Puccinia. 
Metacious, the same as hetercecious.
