892. *D. nigro-paleaceum, Kunze ; D. arborescent, J. Sm. ; 
Asplenium arborescens, Metten. — A beautiful Fern, growing some- 
what plentifully on both sides of the central ridge, and scarcely 
found below alt. 2- 8. Its graceful fronds, six or seven feet long, 
having the lower part of the stalk thickly coated with black hair, 
are easily recognised amongst the Blackberry-bushes, along the road- 
sides on the high land. It is exceedingly difficult to preserve in a 
dry state, as it fades almost immediately it is gathered, and turns 
black. Hk. & B. Syn. Fil. 1868, p. 240.

893. *G. Haughtoni, Hk. — A beautiful little Fern, commonly 
called the Barn Fern, from the circumstance of its having been first 
discovered on the Barn rock. It dies away in the hot weather, and 
soon after the winter rains in June or July makes its appearance 
again, growing on the cliffs of the basaltic rocks on the barren out- 
skirts of the Island, where it lias little if any soil ; but exposed to 
the wind and rain, and sheltered from the scorching sun, its roots 
retain sufficient moisture, while heat is conducted to them by the 
rock. It is somewhat rare, mostly confined to the North and 
North-Eastern parts of the Island, such as the Barn, Bupert’s Hill, 
Ladder Hill, High Knoll, and High Point, its alt. varying from 
1-2 to 3-2. Hk. & B. Syn. Fil. 1868, p. 381. 
Hymenophyllum, Smith. 
894. *H. capillaceum, Boxb. — A beautiful little slender Fern, 
found on the stems and branches of the trees and larger ferns at 
Diana’s Peak, where it appears to thrive well in the moist atmo- 
sphere of that region. Hk. and B. Syn. Fil. 1868, p. 58. — Parasitic 
on Tree-ferns and indigenous Cabbage-trees. Alt. 5 ’4. 
Monogramme, Schk. 
895. *M. graminoides, Baker; M. furcata, Desv. — This Fern 
has been included with those found at St. Helena.
