144 GREENHOUSE FEENS. 



Chili and New Zealand, and other cool parts of the world, so 

 that we shall soon have quite a group of Filmy Ferns ; and we 

 hope then to see our horticultural societies offering special 

 prizes for them, which will much encourage their cultivation. 



HYPOLEPIS. 



A genus of Ferns separated from Polypodium and Cheilan- 

 thes by Bernhardi. Name derived from hypo, under, and lepis, 

 a scale :* the spore-masses being partly covered by a scale. 

 The genus may be distinguished by that character, and by the 

 situation of the spore-masses, which are placed in the hollow 

 or sinus of the frond. There is only one species in the genus 

 in cultivation that will thrive in the greenhouse. 



HYPOLEPIS RUGULOSA (Rather rough). From Yan Piemen's 

 Land. Fronds 2 feet high, thrice-cut; pinnae lance-shaped. 

 Spore-masses round, and covered by a reflexed crenule of the 

 frond. Rootstock very rough with scales, much lengthened, 

 and creeping. Increased readily by division. 



LASTREA. 



Mr. Moore, one of the ablest writers upon Ferns, says 

 that this name was " given in honour of M. Delastre, of 

 Chatelheraut, a zealous botanist and microscopist." This 

 group is one of the best known, but is not generally a favourite 

 for in-door culture. 



LASTREA CANARIENSIS (From the Canary Islands). A 

 strong-growing and rather distinct Fern, with light green 

 fronds, twice-divided, about 2 feet high, with stems covered 

 with light- coloured scales. 



L. DECOMPOSITA (Much- divided). A native of Australia 

 and New Zealand. Fronds triangular in outline and nearly 

 as wide as they are long, repeatedly divided, dark green, 

 spreading horizontally not more than a foot above the
