100 GREENHOUSE FERNS. 



TRICHOMANES RENIFORME (Kidney- shaped), J?%. 72. Native 

 of New Zealand. Fronds about 6 inches high, shining dark 

 green, smooth and semi-transparent, simple, kidney-shaped. 

 Hhizome slender, creeping, and wire-like. It may be increased 

 by division. For the mode of treatment see what is said of 

 the Stove kinds. 



T. RADICANS (Rooting). So named by Swartz ; Willdenow, 

 however, called it T. speciosum, and E. Brown T. Irevisetum. 

 It is not only a native of Ireland, as the popular name 

 (Killarney Fern) would lead us to believe, but is found also 

 in many other parts of the world in fact it grows almost 

 everywhere where a warm and moist atmosphere is to be 

 obtained. Fronds triangular, many-times-divided, light green 

 and almost transparent, growing about 9 inches or a foot long ; 

 ribs of the frond winged. Stalks having narrow brown scales. 

 This elegant Fern is always in request with Fern-growers. 

 It was formerly considered very difficult to manage, but 

 recently we have seen some most magnificent specimens of 

 it. It is perfectly impossible to grow it out of doors, and it 

 even likes the stove better than the greenhouse. There is 

 a variety with narrower fronds named after Mr. Andrews 

 (Andrewsii], an enthusiastic lover of Ferns in Dublin. 



All the species of this genus need to be covered with 

 glasses, and during summer to be kept constantly moist. 



WOODWAEDIA. 



A commemorative name in honour of Mr. Woodward, a 

 rather eminent British botanist. The characteristics of this 

 remarkable genus consist in the spore-masses being much 

 sunk in the leaf with a cover that is hollow like a vault, and 

 by the veins being very much divided into small irregular 

 polygons. 



WOODWARDIA BADTCANS (Rooting), Fig. 73. Very nearly 

 hardy. Native of the warmer parts of North America. It is
