the right, — all the foregoing magnified about 3 diameters; 6, 7, column, 

 magnified ; 8, a petal from Culcer's no. 45, magnified 3 diam. ; 9, petal, 

 and 10, lip of var. Tysoni, from Tyson's 1068. 



Erect, from a span to a foot or more in height. Stem rather 

 straight and rigid, covered from the base with subulate acuminate 

 leaf-like bracts ; leaves 2, radical, appressed to the ground, 

 orbicular with a short acute point, the lower 4-6 cm. long, the 

 upper smaller, spike densely many-fl., cylindrical, 3-5 cm. long; 

 side sepals obliquely lanceolate acuminate spreading, about 7 

 mill, long ; odd sepal erect ovate acuminate concave, equally 

 long ; petals bipartite nearly to the base, ciliolate, the posterior 

 segment adherent to the margin of the odd sepal, lanceolate, 

 anterior segment linear spreading, shorter than or as long as 

 the anterior ; lip 3-partite or 3-lobed, rather fleshy, the middle 

 lobe linear-subulate, usually longer than the similar or narrower 

 and sometimes ciliolate side lobes, spur filiform pendulous some- 

 what inflated towards its apex, about 1 cm. long ; clinandrium 

 somewhat hooded, short, very obtuse, rostellum short with 

 ascending arms, furnished with a rather large tubercle on either 

 side at base ; stigmatiferous processes straight, protruding, 

 longer than the rostellary arms. 



Described from several living and dried specimens. Colour of 

 the flowers pale green, the anther greenish-yellow. A well- 

 marked though variable species, one of its extreme forms being 

 that which I formerly described as H. Tysoni, but which, after 

 seeing and dissecting a larger number of specimens, I now 

 believe should be regarded as a variety merely. The fine closely- 

 set segments of the petals and lip give the spike a mossy 

 appearance, or, as was suggested by another observer, the look 

 of a number of those green web-less spiders which await their 

 prey at the bottom of flowers.
