314 THE VEGETABLE WORLD. 
The Neorrre# are chiefly indigenous to this country, usually 
fibrous rooted, rarely a fleshy bulb, anthers distinct from the column, 
often parallel to the stigma, pollen-grains loosely coherent, nearly 
powdery. The species are generally small, being 6 to 15 inches 
high in the Bird’s Nest Neottia, flowers and stem palg yellowssh 
brown, on an oblong spike; column notched with two short beaks, 
and lobes of the lip divergent; an inhabitant of chalky, shady 
places. Lady’s tresses, Spiranthes, bear small white flowers on 4 
one-sided spike. Found in bogs in the New Forest. 
The Cypripepie# are singularly beautiful in their foliage. The 
form of the flowers is curious, being slipper-shaped; hence their 
name of Lady’s Slipper, of which we have one native species, 
found in the woods of the North of England, but very rare: 
The sepals are ribbed, of a rich dark-brown colour, the two — 
lower ones united. Lip turned, yellow, and marbled, about an 
inch long, reticulated with veins, and spotted internally. 
The exotic species are also dwarf species, but compact and ever- : 
green, the leaves of many of them being beautifully spotted. ’ 
C. barbatum is a pretty species, with beautifully spotted foliage = 
the colour of its solitary flowers brownish purple and white,” 
C. barbatum grandiflorum the foliage is finely variegated, od . 
the flowers considerably larger than the preceding. C. biflora 8 
an Indian species, with variegated foliage, four inches high. The : | 
blossoms produced on a spike ten inches long, the top petal beng 9 : 
beautiful white, and the other part.of the flower a purplish-brown. 
It will have been observed from the preceding remarks Oo 
besides the physiological differences in accordance with be of Z| 
botanists have arranged them, there is a distinct difference e

stones, and rocks, where they receive little or no support wee ae 
their roots. The first, including such genera as Phajus, Calant 
Bletia, Cypripediums, are known as TERRESTRIAL ORCHIDS: © 
others have sometimes been called Arr-PLans, but with a 
propriety they are now termed Eprpuyres. They gto the
