swamps. A few shrubs appear on the dunes and a low ridge bearing 
small trees nearly crosses the cape, as may be seen in fig. 5. 
South of Rehoboth the edge of the frontal ridge of dunes passes 
into a rolling plain called ‘“‘a heath,” and, although the growth 
of the shrubs and stunted trees gives the region a more thicket-like 
appearance, the flora has apparently not materially changed. 
3. Hudsonia complex.—North of Rehoboth may still be found 
the region called a ‘“‘Hudsonia complex,” a jumble of small dunes,

held principally by Hudsonia tomentosa, with swamps occupying the 
depressions between them. The flora of these dunes exhibits a 
more heathlike character than it showed ten years ago. South of 
Rehoboth the drying of the Hudsonia complex has progressed still 
farther. Swamps are rather rare, remnants showing in places, 
where Scirpus americanus(?) and Juncus sp. give evidence of former 
swampy conditions. 
4. Swamps and meadows.—As the flora around Silver Lake was
