distinct forms of frond, and by the spore-masses being naked 

 that is, without any indusium or covering, and the compound 

 crooked lines of veins. 



DRYNAEIA COEONANS (Crowning). This is another East- 

 Indian Fern, and a noble specimen it makes. The fronds are 

 sessile that is, stalkless, erect, somewhat rigid, pinnatifid or 

 deeply-lobed on each side nearly down to the midrib. These 

 fronds are 3 feet or even more in height. The rhizome, 

 covered with amber-coloured scales, creeps, and has always 

 a tendency to turn in a spiral direction. This is also the case 

 with D. morbillosa ; and both in their native countries grow 

 round the stems of old trees, which may, perhaps, account 

 for it. 



D. DIVEESIFOLIA (Variously-shaped-leaved). A very beau- 

 tiful East-Indian Fern, with once-divided fertile fronds about 

 2 feet in length. These are of a delicate light green colour, 

 and as they droop very gracefully the plant is very suitable 

 for cultivation in a suspended basket. The old fronds turn 

 yellow in August, but there is always a crop of new ones 

 ready to succeed them at once. It makes also sterile fronds, 

 shaped somewhat like the leaf of the oak ; these should be 

 left on the plant even after they are brown and dry, for they 

 contrast beautifully with the other fronds. It may easily be 

 increased by division. 



D. IEIOIDES (Iris-like). See Microsorum. 



D. MORBILLOSA ( ?). This noble Fern, was intro- 

 duced from the Malayan Archipelago. It closely resembles 

 D. coronans in appearance and habit, and, indeed, is often 

 confounded with that species. It has the same kind of rigid, 

 erect, stemless fronds, but is broader, more coarse-looking, and 

 not so elegant as that plant. 



D. MUS^FOLIA (Musa-leaved). A rigid, entire-fronded 

 Fern from the East Indies. The fronds are stalkless, and rise 

 at once from the creeping rhizome ; they are of a pale green, 

 and show the arrangement of the veins beautifully, looking
