some shelter, such as a hollow or large piece of driftwood. Next 
in abundance, though but scarce, is the little fleshy, rosette-like, 
annual sea rocket, Cakile edentula (C. americana). Third in abun- 
dance is the low halo-rosette, perennial sea lungwort, Mertensia 
maritima, here seemingly growing as an annual, also mostly in 
places of some shelter. Rarely, and then only in a sheltered position, 
occur tiny radiate-creeping plants of the beach pea, Lathyrus mari- 
timus, growing apparently only as an annual, and sometimes show- 
ing a marked difference in the windward-creeping and leeward-

creeping shocts on the same plant, the former being much shorter 
and smaller-leaved. Even rarer is the radiate-creeping, small- 
leaved, halo-scurfy annual, Aériplex patula hastata. Here and 
there, however, especially in sheltered places, arise the tufted culms 
. the beach grass, Ammophila arenaria, the characteristic sand- 
binding perennial of the dune beaches next to be considered, here 
seemingly growing from seed. I was able to find no other plants 
on the new beach. Thus we see that this vegetation is distinctly 
adjusted to the physical conditions, for it is of great paucity, of small 
and slow growth, annually renewed, closely ground-appressed, and 
Strongly xerophytic.
