276 OECHIDACEJE. 



The Pyramidal Orchis (O. pyramidalis), I found in moist 

 meadows in the county of Durham. The flowers are small, 

 and arranged in a crowded cone : they have more of a rose tint 

 than any other of our native Orchises. This flower has also an 

 agreeable scent. 



The Marsh Orchis (O. latifolia), is a Swaledale trophy. The 

 spike is large and crowded, and the whole plant very strong. 

 The roots of this species and of the Spotted Orchis are palmate, 

 consisting of several elongated knobs. The Marsh Orchis has 

 pale green, unspotted leaves. 



The Aromatic Orchis (O. conopsea), grows freely in meadows 

 about Thiernswood in Swaledale. Its spike is long, and less 

 crowded than those of the two last-named species. It has no 

 spots on its leaves, and its root also is palmate. It is exceed- 

 ingly fragrant. 



The White Orchis (O. albida), has very small flowers, which 

 are closely packed in a narrow spike. It is scentless. 



The Frog Orchis (O. viridis), has fewer and more scattered 

 flowers ; they are larger, and of a brownish-green. Both these 

 species grow in hilly pastures in Swaledale. 



The Dwarf Orchis (O. ustulata), I found on the Wiltshire 

 downs, where it grows freely. I have also gathered it near 

 Sutton in the Hipon neighbourhood. The flower is white, and 

 the calyx blackened, which gives it a variegated appearance. 



The Brown-winged Orchis grows in the chalky districts of 

 Kent, and the curious Monkey and Lizard Orchises are occa- 

 sionally found in similar districts, but are very rare. All 

 these species have two knobs to their root ; one of these pro- 

 duces the flower, and dies away afterwards ; in the meanwhile, 

 the other knob throws out an offset, which shall produce a 

 flower in its turn, and another knob when the present one 

 shall have performed its oflice in life, and decayed like its 

 predecessors. This peculiarity makes the plant move a little 

 every year, so that after several seasons are passed the place of 

 the Orchis is at some distance from that which it first occupied.
