superantibus, sepalo dorsali ovato-lanceolato acuto rubro-purpurascente, 
lateralibus in laminam ovato-oblongam obtusam labello eequilongo supposi- 
tam connatis carneis, petalis sepalis duplo longioribus horizontaliter 
patentibus anguste linearibus pallidis rubro-marginatis, labello oblongo 
‘flavo-viridi, ore amplo margine auriculato, staminodio triangulari-cordato 
- margine purpureo-villoso, ovario 3-loculari.

The nearest ally of this magnificent species is undoubtedly 
C. longifolium (Tab. nost. 5970), which differs in its much 
smaller stature, narrower leaves, spreading sheaths of the 
purple scape, shorter, more obtuse dorsal sepals, and colour 
of the flower. In all essential characters they agree very 
closely indeed, and the almost identical structure and form of 
the lip and sexual apparatus suggest the possibility of their 
being races-between which intermediates will be found. For 
horticultural purposes C. Roezli is incomparably the finest of 
the two, not only in colour, but on account of its size, it 
being by far the largest of the genus hitherto discovered. 
Probably these species would hybridise with facility, but I 
see nothing to be gained by such a proceeding, C. /ongifolium 
presenting no one superiority but the bright red colour of its 
scape. : 
Cypripedium Roezli is a native of New Grenada, where it 
was found by Roezl on the banks of the Dagua river, which, 
according to Regel, occupies a valley between two ranges of 
the Andes. I find, however, no such river on the map, but 
a small town of Dagua on the western declivity of the Andes,
