THE NEW PLANTS OF 1870.

Sieboldii is a hardy perennial, with an erect spike of pretty yellow flowers ; and in 
Cypripedium vexillarium and C. Dominianum we have two interesting hybrid 
acquisitions to the Lady’s Slipper genus, the first obtained between 0. Fairrieanum 
and C. barbatum, the latter between 0. Pearcei and C. caudatum, and both of 
them presenting an intermediate character. 
Palms and Cycads are coming very much into vogue, and form beautiful 
decorative objects while of moderate size. Amongst the many which have been 
brought forward, the following, namely, Cocos Wallisii , Calamus cinnamomea , 
Dcemonorops plumosus , Ptychospernia Alexandras , and Zalacca Wagneri are the 
most important among pinnate-leaved palms, and Pritchardia pacijica among 
fan-leaved palms—these all being new or very little known. Rhapliis humilis , too, 
is another remarkably pretty greenhouse Palm, throwing out its short-stalked, 
small flabellate leaves one above the other so as to give a columnar outline to the 
plant. Lepidozamia Perofiskiana , an Australian Oycad, known also as Macro- 
zamia Denisoni, is a noble greenhouse species, with long, pinnate, spreading 
leaves ; while Cycas Armstrongii and Macrozamia magnified , both Australian, are 
greenhouse species of an ornamental character, the former with bold, the latter 
with slender pinnate leaves. 
Comparatively few new Ferns can be credited to the year 1870, but some of 
the few that have been added rank in the very highest class. Thus Adiantum 
peruviahum is the noblest of all the maidenhairs, and has large drooping fronds 
made up of broad trapeziform pinnules'; it is, as its name indicates, Peruvian. 
Adiantum sessilifolium is another beautiful and very distinct tripinnate species 
from Peru; it is sometimes called A. Henslovianum. The charming Davallia 
Mooreana , a Bornean species of large size and most elegant conformation, had, it 
appears, been previously named D. pallida. In the Peruvian Gymnogramma tartarea 
aurata we have the finest of all Gold Ferns, with large, stout, arching, broad- 
pinnuled fronds, densely aureo-ceraceous beneath. Todea Wilkesiana is a charming 
miniature tree fern, with filmy fronds, and has been introduced from the Feejees. 
All these are stove ferns. Of greenhouse ferns, two handsome and extremely 
useful varieties of Pteris serrulata have appeared ; the one vigorous-habited and 
beautifully multifid-crisped, called P. serrulata major cristata ; the other slender, 
weeping, and remarkably narrow in its segments, called P. serrulata gleichenicefolia. 
A new Lycopod called Selaginella Martensii divaricata albo-lineata is exceedingly 
pretty, the stem near the curving points as well as the stipular leaves being white, 
so as to show, in a good light, a white longitudinal stripe. 
Stove plants are much more numerous, and comprise many useful subjects 
which we are compelled to pass over. Among the most remarkable we note the 
following :— Posoqueria fragrantissima , a Brazilian Cinclionad, with bold leaves., 
and panicles of fragrant white flowers, having a slender tube 6 in. in length. Ixora 
Williamsii is a fine garden variety in the way of I. javanica, with large, compact, 
cymose heads of rich salmon-coloured flowers. Solatium venustum is a Brazilian
