developed as a constant character. 
In the barren spikes of the broad-leaved S. binervosa the assimilating 
tissue is much more developed ; the palisade cells are longer and are three

deep, a feature which recalls the barren scapes ot S. bellidifolia. The 
vascular bundles are also small, and the sclerized zone is only feebly 
developed.

The habitat of this plant at Blakeney Point has been described on 
p. 244. Only plants from the lows were available for investigation. 
1. The Root. 
The structure of the root differs essentially from that of S. binervosa , 
and much more closely resembles that of the salt marsh forms such as 
.S'. Limonium ; it is much less wiry and distinctly more fleshy. The dis- 
tribution of the tissues in the root is shown in Text-fig. 26, A ; a comparison 
with Text-fig. 12, A, shows the very different proportions which obtain 
between the mechanical tissues in bellidifolia , which is essentially a salt 
marsh plant, and binervosa , which inhabits shingle. 
The primary root has a diarch or tetrarch plate of xylem ; secondary 
growth sets in early and produces considerable secondary wood (xy., Text- 
fig. 2 6, a) surrounded by a broad zone of secondary phloem ( ph .). The 
secondary xylem is composed of comparatively few large vessels embedded 
in xylem parenchyma ; occasional wood fibres occur, but the wood is dis- 
tinctly ‘ soft * in type, and very different in nature from that of binervosa 
(cf. Text-fig. 27 and Text-fig. 10). Broad primary medullary rays occur 
opposite the protoxylem groups, and wide secondary rays split up the wood 
into segments and still further increase its parenchymatous nature. 
A broad zone of secondary phloem (/A, Text-fig. 26, a) is produced ; the 
bulk of it is phloem parenchyma. The secondary cortex is a wide zone of
