H ABE N ARIA (from habena, a thong or strap ; spur 

 long, strap-shaped). STN. Sieberia. ORD. Orchidece. A 

 genus of about 400 species of terrestrial stove, greenhouse, 

 or hardy plants with the habit of Orchis, many of which 

 are highly ornamental, and well worthy of a place in any 

 garden. They are found in almost all temperate and 

 warm regions. Among the numerous genera which are 

 now included under Habenaria are : Cceloglossum, Gymna* 

 denia, Phyllostachya, and Platanthera. The species de- 

 scribed below are hardy, except where stated otherwise, 

 and form very pretty plants for boggy places, or other 

 situations, in moist, peaty soil. For culture of stove 

 species of which few are now grown see Bletia. 



FIG. 165. FLOWER OF HABENARIA BIFOLIA CIILORANTIIA. 



H. bifolia (two-leaved). Butterfly Orchis, fl. white, numerous ; 

 lip lanceolate, entire, about half the length of the very long, 

 filiform spur. June. Stem angular, 1ft. high. Britain. Accord- 

 ing to Bentham, this species varies much in the breadth of the 

 leaves as well as of the parts of the flower, and the extreme 

 forms have been distinguished as species, the name of H. chlo- 

 rantha (see Fig. 165) being given to those in which the flowers 

 are large, and the anther cells much more broadly diverging at 

 the base. Darwin, however, regarded H . chlorantha and H. bifolia 

 as distinct species, and states that they require different species 

 of moths to fertilise them.

 fringed, in spikes. May and June. North America, 1820.

 acute, nearly equal, dorsal one horizontal ; petals undivided, 

 galeate, obtuse ; lip entire, ensiform ; spur pendulous, twice as 

 long as ovary, two-lobed at apex. August, h. 1ft. Sierra Leoue, 

 184?. Stove.

 little hardy herbaceous perennial, not unlike a miniature 

 Gloxinia, and with a tufted habit. For culture, see

 HABLITZIA (named in honour of C. von Hablitz, 

 a distinguished Prussian author and traveller). ORD.
