MAIDENHAIR GROWING ON THE PERPENDICULAR SIDE OF A LIME SINK 



The shady or southern side of lime sinks often harbors such a luxuriant growth of this graceful fern that the eroded 



rock wall is completely hidden by drooping masses of brilliant leaves, giving the appearance of a green water fall. 



This plant grows as well on the horizontal hammock floor, concealing from view the numerous little well-like 



sinks. It thus makes walking in the hammocks dangerous. Scattered among the maidenhair may be 



seen a few leaves of the halberd fern, and in the shadow in the left-hand corner are a few leaves 



of the creeping wood fern. On the hammock floor, about the edge of the sink, is a plant of 



the strap fern with erect leaves, and to its right a cluster of leaves of the sword fern
