101 FEKNS AS DKCOUATIVK OBJECTS. 



DiCKSONIE/E, 



70. Davallin elegans. — This species, which is generally dis- 

 trihiited over the East Iiulies, as well as tropical New Holland, 

 has tall siib-coriaceous fronds, three or four times divided. It 

 is, in fact, a highly compound Fern of considerable size, and 

 really very elegant when grown to perfection as a pot-plant. 

 Being a tropical species, it requires a tropical climate under arti- 

 ficial cultivation. 



GliEICHENIACE/E. 



71. Gleirhcnia microplnjUa. — This is an Australasian species, 

 with dichotomously-divitled fronds, the branches pinnate, and 

 the pinnae divided into small close segments. The habit is sin- 

 gular and interesting. It should be cultivated in a warm close 

 greenhouse. 



ScHIZEACEiH. 



72. Lygodium scandens. — A climber, extending 10 or 12 

 feet in lengtli. The stems throw off opposite branches ; these 

 branches are decompound, the divisions being mostly ovate, and 

 on the fruitful parts of the frond fringed round the margin with 

 even, oblong, projecting, teat-like masses of fructification. It 

 is a most elegant climbing plant, native of the East Indies, and 

 requiring a tropical climate. 



73. A?iemia Phyllitidis. — A very distinct Fern, forming a tuft 

 of stems, growing from 1 to 2 feet high, or more according to the 

 strength of the plant and the circumstances of its growth. Each 

 perfect stem bears a barren branch or leaf, and a fertile branch, 

 ■which latter looks somewhat like the close panicle of some 

 grass. The leafy branch is pinnate, with a few large, ovate 

 leaflets, so that the branch has something the appearance of a 

 leaf of the common ash- tree. A good mass is, however, effective, 

 from its distinct appearance. It is a native of tropical South 

 America, and requires a tropical climate. 



74. Mohria thurifrofja. — This is also a distinct-lookingspecies. 

 It forms a pretty pot plant. The fronds are elegantly cut, narrow- 

 lanceolate, sub-bipinnate with short alternate pinnae, and from 

 six inches to a foot long. The pinnae on the barren parts of the 

 fronds bear little oblong piimules, which are deeply lobed, and 

 these lobes are.again cut into several linear segments. The pin- 

 nules of the fertile pinnae are not incised, but bear the sori along 

 the margins. A native of the Cape of Good Hope, and requires 

 a sub-tropical climate. 



75. Osmunda regalis. — A truly noble object, when in a high 

 state of development. It is indigenous, growing in boggy situ-
