Bulbus conoideus, pleroma pallide caesium sub gemmis ad violaceum 

 tendens apice in pallide fiavum transeuns, cortice albido; vel etiam viridi- 

 flavum cortice caeruleo; rhizoma elongatum crassum teres leviter curvatum 

 apice attenuato-obtuso annulis latis, plumbeum, nittidulum; pleroma piope 

 bulbum pallide viridicaesium vel etiam viridi-flavum, cortice tota sordide 

 aibo, ceterum totum pallide flavidum. 



Gaulis et vaginae foliorum pulchre rubrofusca quasi polita, puberula, 

 habitu C. xanthorhizae et C. aeniginosae. 



Folia elliptica maxima suberecta basi et apice acuta, juvenilia fere a 

 basi, adulta a media usque versus apiceni macula intense atro-purpurea 

 vel obscure purpurea ad costam mediam notata, versus basin sensim angus- 

 tiore et delitescente, consistentia valida, intense virridia. 



Scapus semipedalis vel pedalis, vagina summa bractei-formis, ovata, 

 obtusa mucronata apice pallide purpurea basin spicae involucrans. Bractea 

 fertilis externa ceteris parum longior, cum bursa brevi paullum convexa, 

 parte libera apice rotundata marginibus leviter incurvis, Bracteae inferiores 

 fere ad medium adnatae, parte libera obovata, breviora quam lata apice 

 rotundata, acuta, br. intermediae (pleraeque) parte libera oblongo-ovata 

 acuta et mucronata valde convexae. Bracteae comae 4; 7 steriles auguste 

 oblongae apice obtusae vel subacutae insigniter mucronatae.

 totae albae, apice macula purpurea coloratae. 



Bracteolae maximae, tubum coroilae valde superantes. Calyx magnus 

 dorso breviter fissus, subtruncato 3-dentatus. Coroilae tubus brevis ostio 

 lato, faux lata. Stamdia latissima obovata ovato-obtusa. Filam. brevissimum, 

 anthera magna calcaribus elongatis curvulis baud patulis. Stylodia 3 a 4 mm. 

 Corolla inde ab ovario ad apicem labelli 45 mm. longa. 



Bulb 70X40. Rhizome elongate, with long internodes and rare branches 

 but litle curved, fleshy, the top obtuse, outside lead coloured quasi polished, 

 the colour of the internal parts varies between blue, greenish yellow, white 

 and pink. A young and vigorous bulb has mostly a blue pleroma (403 C et 

 D) and a whitish cortex tinged with pink (462) near the upper end is 

 yellowish-white; but sometimes the pleroma is greenish-yellow (287) and the 

 cortex blue (442). The adult rhizome is blue intermally only near its issue 

 from the rhizome and yellow for the most part, but young branches 

 are often more or less blue intermally. 



The stem is dark brown (78 et 83), as for the rest quite resembling 

 C. aeruginosa and the sheaths finely puberulous just as there. 



The leaves are very long, first elliptic, afterwards oblong lanceolate 

 having a cloud along the midrib resembling that of C. aeruginosa, but
