OSMUNDA—PLA TYCERIUM. 



67 



Nothochljsna. — Elegant stove and greenhouse ferns. N. chrysophylla, N. nivea 

 and N. trichomanioides are stove species ; N". Eckloniana, N. Marantoe, N. Newberryi and 

 N. rufa succeeding in a greenhouse. Pot in equal parts of loam, peat, leaf-soil and 

 sand, adding charcoal and small lumps of sandstone. Shady position. Propagated by 

 spores, and by division of the plants at potting time. 



Onychium. — 0. auratum (Fig. 109) is a handsome stove species ; 0. japonicum can 

 be grown in a greenhouse. 

 Pot in equal parts of loam, 

 peat, leaf-soil, and sand. 

 Shady position desirable. 

 May be planted in rock- 

 eries. Increased by spores 

 and by division of the 

 plants. 



Osmunda. — Eoyal or 

 "Flowering" Ferns. 0. 

 japonica corymbifera, 0. 

 javanica and 0. palustris 

 may be grown in either a 

 greenhouse or conservatory. 

 Pot in equal parts of fibrous 

 loam and peat, adding 

 river-sand. A moist, shady 

 position is necessary, and 

 abundance of water during 

 the summer. Propagated by spores and by offsets from established plants in April. 



Phlebodium. — Nearly allied to Polypodium ; requiring identical treatment. The 

 species principally grown are P. aureum (Golden Polypody) and P. sporadocarpum. 



Platycerjum. — Stag's Horn Fern. Distinct from all other ferns, and some of them 

 quaintly beautiful. P. alcicorne will succeed in a greenhouse or conservatory, but this 

 and its variety, P. alcicorne majus, P. grande, P. Hilli (Fig. 110), and P. Willincki are 

 found to make the best progress in a stove. All ought to be grown on blocks of wood 

 suspended from the roof or sides of a house. Cover the roots with a good thickness of 

 peat and sphagnum moss, and secure with copper- wire. Propagated by offsets.
