usque ad prope apicem supra macula lata quasi pinniformi in utraque 

 parte secus cüstam iiotata, parte inferiore semper tota viridi subtus con- 

 colore, glabra, vagina longa puberula, ligula fere striata. 



Scapus brevis vel usque pedalis rare semimetralis, vaginis paucis 

 appressis rotundatis et mucronatis, superioribus binis vel summa tantum 

 bracteiformis basi spicae adnata. 



Spica vulgo laxiuscule bracteata bursis mediocribus vel brevibus 

 convexis, bracteis puberulis vel glabris. Bracteae erecto-patulae, latae, 

 omnes obtussimae vel rotundatae, inferiores rotundato-ovatae vel subo- 

 bovatae parte libera, bursa longiore, latiore quam longa, intermediae paullum 

 longiores, superiores comam sistentes late eliipticae, vel summae steriles 

 oblongae apice rotundato mucronulato, omnes valde induplicati canalem 

 angustam versus apicem dilatatam sistentes. 



Flores inter minores bracteas hand superaiites, bracteolae parvae tubo 

 corollae vix longiores. Calyx brevis apice subtruncatus, dentibus 3 subae- 

 qualibus brevissimis (V2 mm.). Petala ovata cum fauce rubro-brunnea, 

 obtusisima, dorsale valde cucullatum. Corollae tubus brevis, faux brevis, 

 lata. Labellum subrotundum (14X15 — 17X17) parte mediano breviter 

 bilobo vix prominente, vix unguiculatum sulfureum. Staminodia obovata 

 apice rotundato-truncata, lateribus fere rectis filamentum brevissimum, 

 aequilatum, anthera majuscula calcaribus mediocribus; stylodia longa. 



Bulbs large, conical. 



Rhizomes numerous elongate cylindric somewhat inflated in the mid- 

 dle (160 X 30), proceeding at all sides, 2 or 3 one above another, 

 simple or composed of 2 or 3 members forming a sympodium, all 

 as well as their branches (sessile tubers) which are few and long, 

 growing as much as possible in a horizontal direction and faintly incurved, 

 with blunt tips. Externally they are lead-coloured and polished, the tips 

 white (if growing), tinged pink; internally the plerom of bulbs and rhizomes 

 is blue, often with a faint greenish tinge, mostly sordid blue or even 

 blue violet (447 and 467) under the buds, the cortex is white or the 

 inner part blue (428 D, 453 D). The plerom of a young rhizome was 

 between 396 and 396, the cortex almost white or also 353 D, a very 

 diluted „verdigris." 



The pendulous tubers are numerous and large, suspended by not very 

 long (10 — 200) thick fibres; they are 100X20 or 45X25 long, ovate 

 or fusiform, attenuated at both ends, the colour is pearlgrey with a white 

 centre. The stem is (400 - 500) X (30 = 20). The petioles are 0—50— 180 

 mm. The disks of four measured leaves were: 640— 215. 600X^80 (the 

 inner), 550X175, 450X120. (P = 3). 



Of an other plant of 7 leaves the dimensions were 

 Outer leaf 450 X 160 -f 0. P. = 3.
