446 GENLISEA ORNATA. Cuap. XVIIL. 
GENLISEA. 
This remarkable genus is technically distinguished 
from Utricularia, as I hear from Prof. Oliver, by 
having a five-partite calyx. Species are found in 
several parts of the world, and are said to be “herb 
annue paludose.” 
Genlisea ornata (Brazil).— This species has been 
described and figured by Dr. Warming,* who states 
that it bears two kinds of leaves, called by him 
spathulate and utriculiferous. The latter include 
cavities; and as tliese differ much from the bladders of 
the foregoing species, it will be convenient to speak of 
them as utricles. The accompanying figure (fig. 29) 
of one of the utriculiferous leaves, about thrice en- 
larged, will illustrate the following description by my 
son, which agrees in all essential points with that 
given by Dr. Warming. The utricle (0) is formed 
by a slight enlargement of the narrow blade of the 
leaf. A hollow neck (n), no less than fifteen times 
as long as the utricle itself, forms a passage from the 
transverse slit-like orifice (0) into the cavity of the 
utricle. A utricle which measured , of an inch 
(‘705 mm.) in its longer diameter had a neck +: 
(10583 mm.) in length, and +4, of an inch (‘254 mm.) 
in breadth. On each side of the orifice there is a long 
spiral arm or tube (a); the structure of which will be 
best understood by the following illustration. Take a 
narrow ribbon and wind it spirally round a thin 
cylinder, so that the edges come into contact along its 
whole length; then pinch up the two edges so as to 
form a little crest, which will of course wind spirally
