Raised by Seden at our nursery. It is one of the comparatively few 

 hybrid Cypripedes in which the characteristics of the seed parent pre- 

 dominate in the flower, and those of the pollen parent in the foliage ; 

 the influence of Cypripedium superbiens is seen only in the spotting 

 on the basal half of the petals and in the large helmet-shaped lip and 

 in the staminode. 



C. Madame Van Houtte. 



Parentage doubtful; probably Cypripedium niveum and one of the species 



of the C. venustum group (C. barbatum, &c). 



Upper sepal folded at the mid-vein, pale vinous purple with a broad 

 white margin and yellow-green veins; lower sepal milk-white with bright 

 green veins ; petals light vinous purple, paler on each side of the deep 

 purple mid-veins, the other veins yellowish green ; lip dull rose-purple, 

 the infolded lobes ivory-white. Staminode ivory-white tinted with rose 

 and with a yellow stain in the centre. 

 Cypripedium Madame Van Houtte, supra.* 



Supposed to have originated in the horticultural establishment of M. 

 Louis Van Houtte at Ghent ; but although so little is known of its 

 origin, it is far too distinct and handsome to be omitted from these 

 pages. The only plant raised has been acquired by M. Hye Leysen, of 

 that city, the possessor of one of the choicest collections of Cypripedes 

 in Belgium. 



0. marinorophyllum. 



G. HooJc&roB X G. barbatum . 



Leaves handsomely tesselated with dark and light greyish green, the 



latter predominating. Upper sepal green passing into white at the 



margin, and with a pale purple stain on each side of the mid-vein 



which is dark purple, the other veins dark green ; lower sepal pale 



* We are not aware of the name having been previously published. Our Belgian informant 

 who brought the flower from which the above description was taken, believed it was the 

 intention of the owner of the plant to give it the name under which it is described above.
