Ci Pap he Lindenia has already figured several remarkable varieties of S. cau- 
ba b EY datum. This superb Orchid, described for the first time by Linp ey after 
la dried flower from the herbarium of Ruiz and Pavon, was introduced 
into culture about the year 184g or 1850. As regards elegance, peculiarity of 
form, and size of the flowers, it is certainly the most beautiful of the Seleni- 
pedium genus, and of the Cypripedium tribe. 
The Wallisi variety was discovered in 1872-73 by Gustave Watts, whose 
name it bears; it is characterised by the much paler coloration of the flowers, 
notably of the lip, which has pure white lateral lobes. 
This variety is a native of the Ecuador, and has also been found in the 
Huanuco district, in Peru; the type is most frequently met with in New Granada, 
and in the Peruvian Andes. There are several geographical forms existing, 
variable both in form and coloration. 
The plant we now figure bears undoubtedly some affinity with the Wallisi 
variety, but may be distinguished from it by the coloration of the flowers; the 
lip is tinged with rose towards the apex, outside and inside, and bears, along 
the orifice formed by the recurvation of the lateral lobes, a narrow brownish- 
yellow band. The sepals are tinted with brighter green than in the common 
form, and the petals, striped longitudinally with green, are tinged with rose from 
the part were they grow narrow. 
This curious and very distinct form has appeared to us worthy of being 
dedicated to the distinguished French Orchidist, Madame VANDERSTRAETEN. 
As regards culture, the Selenipedium may be considered as the most nisile 
and vigorous of the representatives of the Cypripedium tribe. S. caudatum is
