96 Hill.—The Structure and Development of 
Inflorescence and Flowers. 
The inflorescence of Triglochin maritimum consists of a 
raceme, the flowers being attached by very short pedicels 
to the peduncle. The flowers in each inflorescence are very 
numerous, and are especially crowded at the apex of the 
flowering stem. 
An interesting fact, which has already been recorded in 
connexion with the inflorescence of this plant by Van 
Tieghem (14 and other observers, is that the apex of the 
flowering stem is very frequently occupied by a flower. 
The individual mature flowers, which have no bracts, are 
greenish in colour, although they sometimes have a very 
decided purple hue. 
The perianth consists of six segments arranged in two 
alternating whorls of three lobes, the segments of the outer 
ring being somewhat larger than those of the inner. The 
stamens are six in number, arranged in two whorls, alter¬ 
nating with those of the perianth. 
The ovary is made up of six carpels which, early in life, 
become attached to one another, separating when the seeds 
are ripe. Each carpel has a single feathery stigma, and 
contains one seed. The fruit of Triglochin maritimum is 
not nearly so long as the fruit of Triglochin painstre , but 
is very much broader. 
Flower-development. 
Cordemoy ( 4 ) worked out the floral development of Tri¬ 
glochin palustre , and his account, which unfortunately is not 
illustrated, closely corresponds to what has been found to 
obtain in Triglochin maritimum , excepting, of course, the 
fact that in Triglochin pahistre one whorl of carpels is 
suppressed. 
The flower first arises as a spherical outgrowth, which is 
illustrated in Fig. 15. 
The perianth is the first of the floral structures to arise, 
and, for the sake of clearness, the components of the outer
