Monoecious. Rhizome hypogaeous, short, thick, shortly ra- 

 mose into volvas and irregularly lobulatc, very minutely granu- 

 lar in surface; not pastulate, about 3.2-lcm. in diameter in my 

 specimens. Volvas not large, shortly and irregularly few-lobed 

 at mouth; lobes erect, depressed-deltoid. Scape one to each 

 volva, erect, rather elongate, terete, more or less striate, 

 glabrous, loosely covered with scales throughout, about 

 8cm. long, |— lcm. across. Scales rather many, scattered- 

 imbricated (the scape visible superficially among scales), usually 

 incurved-crect-patent, lato-ovate, elliptical, or suborbiculato- 

 ovate, obtuse, entire, smooth, concave within, thickish towards 

 the centre, membranaceous towards the margin, about §— 2Jcm. 

 long, J— 2 J cm. broad. Peduncle short, thick; bracteal scales 

 placed under the head, numerous, unequal in size, very short, 

 minute, usually lunate or deltoid, frequently connate. Heads 

 erect, globose or ovoid, about 13— 18 mm. in diameter, bisexual. 

 Male flowers annulately looser-disposed in width of 5-7 mm. in 

 2— 3— rings at the base of the head, 4-5 J mm, across, pedicellate; 

 pedicel a little longer than the perianth, thickish, terete, straight, 

 2l-31mm. long. Perianth-lobes 3—6, patent or slightly reflexed, 

 subequal, elliptical to oblong, obtuse or acutish, thickish, con- 

 cave and longitudinally 1-2— elevato-lineate within, 2— 3 mm. 

 long, 1-2 mm. wide. Stamens united into one, shorter than 

 the perianth, erect, short, about 1J-1§ mm. long; column thick, 

 often somewhat angulatc; anthers 3-5, capitate, depressed- 

 globose ; authcr-cclls doubly and parallelly hippocrepiform. 

 Female flowers exceedingly numerous, densely packed, minute, 

 disposed in the circumference and at the lower portion of spa- 

 diceous bodies ; ovary shortly stipitate, ellipsoid or subglobose; 

 style filiform, long, about 2-1-times as long as the ovary, often 

 somewhat exceeding the spadieeous body. Flavescent-carneous.

This differs from the type by having the globose head, 

 smaller male-flowers, elongate scape, loosely imbricated scales, 

 and more minutely granulated rhizome.
