THE AQUARIUM, JANUARY, 1895.

we think it would flourish in the room 

 without the ghiss. 



AspJeninm inequalifoliinn is some- 

 what simikir to the last, but the fronds 

 are not so finely cut, and the young 

 plants upon their upper surface are not 

 so numerous. The plant is also larger 

 and much more hardy. As its name 

 implies, the fronds are unequally dis- 

 sected, some being quite coarse and 

 others fine, which gives the plant a 

 singular but not unpleasing appear- 

 ance. This is a desirable addition to a 

 collection. 



Scolopeiidrmiu nredulcdum or Hart's 

 Tongue has thick leathery fronds, 

 which are mostly undivided, eight or 

 ten inches high, and are produced very 

 rapidly. It has a thin creeising stem, 

 much branched, soon fills the pot and 

 reaches over the rim, adhering by its 

 hairy roots to the moist sides of the 

 pot, and throwing up leaves so thickly 

 that the whole vessel is soon completely 

 hidden. 



Scolopendrium oficenarum is similar 

 to the last but grows more slowly and 

 never shows so many fronds at the same 

 time. The edges of the leaves have a 

 wavy appearance. Both of these are 

 very desirable. 



Lomaria gihha is one of the most 

 beautiful ferns known. It is of very 

 regular, graceful and rapid growth, 

 and forms a stem with age. The 

 growth of our specimen has not been 

 interrupted in the least during the 

 coldest weather. Any one who will 

 give this plant reasonable care will find 

 it satisfactory in every respect. 



Xeplirolepis exaJtata is the sword fern 

 so much used in hanging baskets. This 

 is too well known to need description. 

 It is of the easiest cultivation, and in- 

 dispensable, no matter how small youi- 

 collection may be. 



Pteris tremula is another well known 

 and easily managed species. The only 

 objection to it is, that its growth is so 

 rapid, under careful cultivation, that 

 it soon becomes too large to handle con- 

 veniently. It should be placed out of 

 doors in the shade during the summer, 

 and frequently shifted. 



Pteris argyrea is a showy species 

 with fronds from two to four feet long, 

 of a silvery white color, with light 

 green margins. It is a rapid grower, 

 but rather tender. 



Pteris cretica alba lineata is a very 

 attractive fern, with fronds about a 

 foot long, very bright green, with a 

 broad white stripe running through 

 each penuce. It is very easily managed. 



Pteris serulata. This old Chinese 

 fern, with its grass-like foliage, will 

 thrive under almost any kind of treat- 

 ment. Nothing seems to kill it except 

 frost or red-hot mid-summer sunshine. 

 It is indispensable in a collection. 



Pteris serulata cristata is similar to 

 the last, but has broader and more 

 erect fronds, with the apices beautifully 

 crested. It is equally hardy. 



\ye might go on to enumerate many 

 others no less beautiful and desirable, 

 but we only promised to mention a few 

 of the most common and easily culti- 

 vated as a sfuide to beginners. 



THE LATTICE OR LACE PLANT. 



( Ouviranda Fenestralis. ) 

 One of the most curious plants which 

 have recently engaged the attention of 

 those who are interested in floriculture 

 and kindred growth, is a specimen 

 known as the lattice plant, of aquatic 

 habits, and brought from Madagascar 

 as a rare acquisition. Its existence has 

 for a considerable time past been 

 known to botanists through a few
