Har. Circa Portum Jackson. Brown. A. et R. Cunning- 
ham. : 
Radix fibrosa, fibris paucis crassiusculis simplicibus: tu- 
bera 2, globosa, magnitudine pisi sativi. Caulis erectus, 
spithamzeus, gracilis, simplex, monophyllus. ` Folium paullo 
supra basin caulis insertum, cordatum, obtusum, reticulatum, 
sinu profundo angusto. Flores racemosi, subspiraliter inserti, 
erecti, bracteati; bracteis subulatis germine brevioribus. 
Perianthii erecti foliola 3 aristata; quorum superius magnum 
ovato-oblongum, valde concavum, subfornicatum ; 2 lateralia 
labello supposita, linearia: 2 interiora minora, lineari-subu- 
lata. Labellum erectum, oblongo-ovatum, acuminatum, disco 
convexo, cujus margines preecipue papulosi. Columna inclusa 
subteres, labello paullo brevior. Anthera hemispheerica: 
Masse pollinis 8, per paria approximata, granulosa. 
On account of the small size of the flowers and the readi- 
ness with which the pollen-masses are disturbed, when the 
anther is removed, I could not satisfactorily detect the arrange- 
ment of these bodies in the cells of the anthers. The Genus 
Mr. Lindley places with his Malazidee, but he considers it 
to hold a middle rank between that tribe and the Arethuse 
on account of the structure of the pollen.
