Lip obovate with a narrow claw and a broad somewhat protruding midlobe, 

 sidelobes very broad upcurved ; 16 X 15 (with the claw), length of the labellum 

 with the faux 24. Filament 4X2, anther 4 mm. long with 2 mm long 

 straight spurs grooved distinctly on the face by a prolongation of the 

 thecae as in Paracurcuma. 



"Flowerbracts bright green, coma bracts purple. Petals pink, labellum 

 bright yellow". 



West Sumatra, garden of Sibulangit in grassy and shrubby wastes on 

 fertile ground. (Lörzing 1248, 20 th Feb. 16). 



This species has a striking resemblance to C. siimatrana Miq. by the 

 broad very obtuse, or even truncate or subretuse bracts which in the 

 lower portion of the spike are adnate far more than halfway, like those 

 of C. petiolata. Miquel however describes the spike of C. suniatrana as 

 central while, trusting Lörzing, here the spike is lateral. 



Among the lateral species, this species comes nearest to C. Mangga, 

 which has also rounded flowerbracts, and the flowers and anthers are very 

 similar; but the separated protruding midlobe of the labellum of C. mangga 

 is wanting here, the antherspurs are not furrowed in C. mangga, the stami- 

 nodes more plicate etc: By the rigid, fleshy structure of the leaves it is 

 only to compare with C. xanthorhiza, and by the pale seegreen colour of 

 the leaves below, it differs from all other species here described.

Herba fere metralis. Buibi médiocres (60X50) vulgo congregati. Rhi- 

 zomata pauca brevia crassa horizontalia internodiis brevibus, apice sursum 

 geniculato-reflexa et statim bulbum novum formantia ramis primariis et 

 secundariis paucis irregularibus, omnibus gemma acuta incurva terminatis 

 et gemma ultima sequentis ordinis eodem tempore cum gemma terminali 

 evoluta, quasi bifurcationem sistente. Omnia extus pallide sordide flava, 

 intus dilutissime flava. Gustu amaro. 



Tuberi filipenduli forma sat diversi, partim oblongofusiformes basi in 

 radices attenuati, partim parvi fere orbiculares hand longe stipitati. Omnes 

 intus albido-grisei. 



Folia dimorpha, caudato-acuminata, omnia concoloria viridia, supra 

 secus venas minute appresse puberula, patentia. In herba luxuriante florente 

 omnia late rotundato-ovata vel subcordata, maxima, latissima, omnia breviter 

 petiolata. In herbis serins florentibus, altioribus, folia sensim longius petiolata et 

 basi minus rotundata, summa (intcriora), sub inflorescentia, lamina oblongo- 

 ovata basi attenuata subacuta sensim in petiolum longum decurrentia. P. 

 in fol. inferioribus 1.5 — 2, in superioribus 2.7.
