242 Wilson . — The Mucilage - and other 
Examples of species possessing very numerous and large 
glands are: — Statice rosea , fruticans , vS. macrorrhabdos , 
vS\ inacrophylla , vS. tatarica , S. gummifera, S. join-barb a, etc. 
In vS. axillaris > S . pectinata and cylindrifolia they are large 
but few. 
Mucilage-glands appear in the axils of the bracts of some 
species, e. g. 5 . eximia and S. pectinata , and in the axils of 
the leaves of small vegetative shoots on the rachis of 
Gongetiana. In most herbaceous species of Statice the 
mucilage, if not welling up visibly, can be seen by pushing 
the leaves away a little from the axis. 
Armeria. 
Mucilage-glands appear in the axils of all the species of 
Armeria enumerated above. Specimens of A. vulgaris (A. 
maritimd) were examined from Ben Ledi, Cairngorm, and 
other alpine stations, as well as from different maritime ones. 
The conditions of growth obtaining on the summit of a moun- 
tain are very different from those in the mud-flats of an 
estuary, but no differentiation indicative of a particular habitat 
is noticeable in the glands. A portion of a sea-pink, from the 
salt-marshes of the river Eden, in Fife, is figured, as seen in 
the winter season (Fig. 23). It is so deeply placed in the 
damp salt soil that nothing but the rosettes of leaves are 
visible. These terminate branches which are united to form 
considerable patches of the plant. The ‘collars’ and upper 
regions of the branches are protected by a thick felt formed 
of the bases of dead leaves, in the axils of which the remains 
of glands occur. A nucleus and nucleolus were noticed in 
a young fresh secreting cell. The mucilage-glands are of the 
same type as those in Statice ; but the basal cells are com- 
paratively few in number. They are scattered over a narrow 
area close to the axils. The petiole is distinctly amplexicaul. 
The axillary glands of Armeria vulgaris , var. calif ornica , are 
relatively few and fine. In A. chilensis , as grown from seed 
at Kew, the great majority of the glands have only four basal
