C. cf. nurii 'Bintan'

My friend located C. cf. nurii 'Bintan' two weekends ago and passed me some specimens with unopened spathe (as usual, haha, do note that I have only managed to "bloom" C. pontederiifolia and C. wendtii from scratch up till now :-p). The spathe opened yesterday and below are some photographs to share with you.

If you search on the internet, you will realised that these plants have been considered as C. nurii 'Bintan' by many, probably due to its elongated leaves with undulated margin and faint leaf veins. However, the spathe is slightly varied from that typical of C. nurii (i.e heart-shape limb being perpendicular to the tube). More checks and verifications are required to confirm if they could indeed be identified as C. nurii.
