d 68), and mature and immature flowers enclosed by the same 
brae (see figs. 81 and 86). 
The flowers begin to occur 
cpa within eg axil of 
e first pair of leaves in each 
daca, oe there is denned 
an outlying pair of leaves below 
the fascicle which does not con- 
tain fi 
the 
touch. T male fowie are 
rarely solitary, but occur in Lites 
threes, or fours; in the earlier 
stages of devalopeliegs pie are 
sometimes more numerous. The 
male flowers are more often soli- 
tary. In the centre of the fascicle 
are the youngest flowers (see figs. 
68 and 69). 
In appearance the flowerslook 
as if they were ordinary anthers 
and pistils, 7.¢. eg they possess 
no perianth ; r. Magnus 
has shown that ‘thik outermost 
covering is really a perianth 
which more or ‘Tees closely invests 
the anthers and pistils. In fig.

vey, in the accompanying figures, 
accurate representations of reach.

with a long neck which bifurcates Fa ita free end (figs. 68 and 70), 
like the bifid stigma of a Carex, such as C, ovalis. The outer 
covering is the perianal: the body which it encloses is the pistil.
