CYpRIPEDIUM niveum, H. Reichenbach in Gard. Chron. 1869, p. 1038. 
This very singular plant was originally described by 
Professor H. Reichenbach in the Gardener's Chronicle, who 
correctly points out its affinity with the Burmese C. concolor 
(Tab. Nost. 5513), whilst keeping it distinct, an opinion in 
which I entirely concur. Wide as are the limits of variation 
in Orchidee, these less concern the Cypripedia than many 
other genera, and in this case the points of discrepancy 
between C. niveum and concolor affect many parts of the 
structure;—thus in C. niveum the bracts are much smaller 
and of a different form; the ovary is longer; the upper or 
dorsal sepal far broader; the lateral sepals are combined into 
one remarkably small notched blade, not one-fourth the size 
of the upper sepal; the petals are considerably broader ; the 
lip much smaller, of a wholly different shape, with a con- 
tracted instead of an expanded mouth ; and the staminode 
is broader than long ;—to these structural differences must
