Spica mediocris, lata (160—230 X 80—100), baud dense bracteata. Bursae 

 bractearum parte libera breviores ('/a— ^/ô). apertura lata vix lateraliter 

 compressa. Partes liberae late ellipticae acutae, erecto-patulae apice vix 

 patentes, pallide virides rubro-marginatae + 15 superiores paullum longiores, 

 pro maxima parte rubro-violaceae, basi viridi-striatae. 



Flores médiocres vix protrusi. Bracteolae tubum vix superantes. Calyx 

 corollae tubo dimidio brevior. Corollae tubus elongatus (^s tloris longitudinis 

 aequans), ostio lato. Faux brevis late cupularis basi annulo setorum crasso 

 instructa, basi baud attenuata. Labellum suborbicuiare lobo mediano retuso 

 vix prominente. Staminodia iatissima, flabellato-plicata, obtusissima. Fila- 

 mentum longius quam latum. Antbera crassa brevis, calcaribus validis thecis 

 circiter aequilongis, connectivo dorso minute glanduloso puberulo. 



in all its parts tbis species is distinguisbed by its colossal dimensions. 

 A full-grovi^n tuber is 100 X 80, but often still larger. From tbis tbe rbizomes 

 issue in a small number, sometimes tbree above eacb otber, longSO X 35, 

 witb 6 internodia, 65 X 40 with four iiiternodia, 35 X 30. From the 

 underside a little number of tbinner side-brancbes, wbicb are upcurved and 

 form new tubers. Internally all parts are dark-orange or orange-yellow 

 (151 — 156), sometimes red-orange like tbe roots of Dauern caroia (131). 

 Young parts 161 and 166. Tbe accessory roots, wbicb issue in a great 

 number from tbe wbole tuber, are thick, fleshy (5—10 mm.) about a length 

 of 60 — 70 mm., below they become filiform and form large fusiform pen- 

 dulous tubers on distances from 50 — 300 mm. Tbe length of these is 60 X 20— 

 100 X 25. Tbe roots and root-tubers (the latter about their entire section) 

 are internally deep-orange when old. The young ones however at first 

 milkwbite, afterwards lemon-yellow. 



A well-growing plant attains a beigth of 2 meter. 



In a plant, which bad nearly attained its full growth and about three 

 months old, the spurious stem was to the youngest sheaths 750 high and 60 

 broad (much compressed). Tbe plant had 8 leaves, of which only one bad 

 fallen off. The dimensions of these were: 



The leaves are thus rather narrowly oblong-elliptical, tbe greatest breadth 

 was in the middle, gradually acuminate with short cusp, passing over tbe base 

 without a line of demarcation into the short broad canaliculate petiole. Tbe 

 line between the blade and the petiole above is indifferently taken on a
