hairs including the rachis of the raceme, with 2 membranaceous adpressed 

 sheaths at the base. Leaves 2, placed in the middle of the whole plant, 

 oppositely approximate, patent, orbiculato-snbreniform, obtuse or acutish at 

 the apex, broadly truncato-subcordate below and very slightly jiroduced at 

 the sessile base, entire and more or less crispulate on margin, membranaceous, 

 glabrous, 18-25 mm. long, 25-30 mm. broad, 7-nerved, the outer nerve 

 with an external branch ; reduced leaves few (about 2), loosely disposed on 

 the stem between leaves and raceme, adpressed or erect-patent, subulate, 

 acuminate, squamiform, glabrous, viridescent, about 2^ mm. long. Raceme 

 erect, loosely about 11-flowered, about 4-5 cm. long ; rachis filiform, straight; 



bracts erect-patent, apparently shorter than 

 pedicels, ovato-subulate, deltoid-subulate, or 

 lato-ovate, acumiuato-acute, membranaceous, 

 1-nerved, 1^-2 mm. long. Flowers small, 

 luteo-viridescent ? ; pedicels erect-patent, 

 gracile, pubescent, about 3^-4 mm. long. 

 Perianth equal in length, obtuse, mem- 

 branaceous, 1-nerved, about 2J mm. long. 

 Sepals : the superior one {Fig. III. 1.) 

 ovato-lanceolate ; lateral ones {Fig. HI. 2.) somewhat oblique in form, 

 lanceolate-oblong. Petals {Fig. III. 3.) linear. Labellum {Fig. III. 4.) 

 twice as long as the perianth, lato-linear below, divergent with 2 short- 

 oblong obtuse and slightly oblique lobes above, with a minute point in the 

 bottom of the open sinus, the median vein thick, veins which run to the 

 lobes 3 and simi)Ie or sometimes forked ; basal teeth very minute and obsolete. 

 C'olunin about 2 mm. long ; anther lato-ovate, obtuse and very shortly bifid 

 at the apex ; rostellum orbicular ; stigma roundish. Ovary oblong, glabrous,

This has a resemblance to Listera puberula Maxim, from Western 

 China, but differing from it by the form of leaves and sepals, and the length 

 of the labellum. It comes also near to /.. Savatieri Maxiu)., but also differs 

 from the latter by the ioYU\ and position of leaves, and the form of the labellum.
