or reddish flowers towards the end of Summer. The Bee Orchis, 
Ophrys apifera; Fly Orchis, O. muscifera; and the Spider 
Orchis, O. aranifera, are so named from the resemblance their 
flowers bear to those insects. The Helleborines, Cephalanthera, 
have leafy stems and white or rosy flowers. C. grandiflora, 
with large white flowers, is a very conspicuous plant in copses 
on a chalky soil. A very common species is the Twayblade, 
Juistéra ovata, a plant about 18 inches high, with two opposite 
oval ribbed leaves, from between which springs a long slender 
raceme of yellowish-green flowers. None of these plants are 
of easy culture, and perhaps the terrestrial less so than the 
epiphytes, of which there are no hardy species. But still some 
careful gardeners contrive to grow some of them successfully, 
such as the Lady’s Slipper, Cypripedium Calcéolus (fig. 226), 
a rare indigenous plant with reddish-brown and yellow flowers, 
found in two or three localities only in the North of England. 
There are several more showy North American species; as 
C. guttétum, purplish-violet spotted and edged with white; 
C. céndidum, white; C. spectdbile, white tinged with purple, 
etc.

The species of Banana, Musa, are employed in the open air 
during Summer in sheltered localities for the sake of their 
broad effective foliage. They are stemless or caulescent herbs 
with large simple sheathing leaves often several feet long and 
spathaceous flowers which are not produced without the aid of 
artificial heat. MM. Sinénsis, M. coccinea and M. Enséte, ete. 
are the species in general cultivation. But these are so rarely 
seen that detailed descriptions would be of little service. 
Orver VIIL.—MARANTACEA, 
This is another order of almost exclusively sub-tropical plants 
recently come into vogue for Summer bedding, which on account 
of their smaller stature, annual stems, and tuberous roots, are 
better suited for that purpose than many other tender plants. 
The structure of the flowers is somewhat singular. Perianth 
superior, composed of 6 segments in two series, the 3 outer 
forming a 3-lobed calyx, and the 3 inner a tubular irregular
