152 THE FLORIST. 



L. oreopteris apart from the original, and 1 believe I may say the 

 same of L. thelypteris. The stations for L. oreopteris are very 

 limited in the south of England, though very plentiful in the north, 

 as well as in Scotland. 



ASPIDIUM. 



It is necessary here to observe that the genus Lastrsea is very 

 justly established on the ruins of Aspidium, in consequence of the 

 marked difference in the structure, &c. of the indusium or involucre. 

 In Aspidium it is nearly orbicular, whereas in Lastraea it is orbicu- 

 lar-reniforme, which was also, I believe, the origin of the genus 

 Nephrodium ; and as the shape, substance, and position of the invo- 

 lucre, where present, form an essential part in the generic charac- 

 ter of most of our Ferns. The division, therefore, I consider to be 

 highly necessary ; besides, the two genera are, in general habit, very 

 different. 



1. A. LONCHiTis. The habitats of this pretty Fern are mostly 

 the clefts of rocks in mountainous countries, notwithstanding which 

 it is not particularly difficult to cultivate, if planted in light sandy 

 loam and peat, and removed at the commencement of the growing 

 season ; for if left until the resting state, it is but too often inclined 

 to remain so for a long time, and then damp oflf ; but if potted in the 

 early spring, and shut close under glass, it will soon adhere to the 

 fresh soil, and send up beautiful fronds, at which time it is best to 

 plant it out where it is intended to remain. I find the above mode 

 of culture suits this Fern extremely well. The fronds are pinnate, 

 and the pinnae eared above.

NEW PLANTS. 



Figured in the Botanical Magazine for May. 



Mangifera indica. An evergreen stove-tree, principally known for its fruit, 

 which is universally eaten, and esteemed the best in India : jellies, preserves, 

 tarts, pickles, &c. are made of it before it is ripe. The tree attains the height 

 of from thirty to forty feet in its native country, and from ten to fifteen feet in 

 circumference ; it bears a profusion of small yellowish flowers of but little beauty. 



Gynoxys fragrans. a coarse-growing soft-wooded climbing stove-plant, of 

 but little beauty ; well adapted for covering rafters or trellis-work ; it has a thick 

 fleshy root of the nature of a tuber ; flowers rather large and fragrant, (something 

 similar to a Senecia). It is a native of Guatemala, and was imported by Ure 

 Skinner, Esq. 



Veronica Formosa. A very pretty half-hardy evergreen shrub, of a neat 

 appearance, growing about two feet high, having flowers of a light blue colour, 

 produced from the end of almost every branchlet : it flowers copiously during the 

 summer months, and forms an interesting object for a greenhouse or conserva- 

 tory. It is a native of Mount AVellington, in Van Dieman's Land. 



IxoRA BARBATA. This is an erect slender rather straggling-growing stove- 

 shrub (something near I. laxiflora), about six feet high, having large spreading 

 subcorymbose panicles of very fragrant delicate white flowers. It was imported
