Tue discovery of this new species adds another to that. small group of Eastern Cypripedia which are justly regarded as 
the handsomest in the genus. Before the introduction of the subject of our present plate, there were eight species of the 
group known. These are C. platytenium, glanduliferum, Stonei, Parishii, philippinense (lavigatum), Roebelenii, Lowii 
and Haynaldianum. All of these differ materially from the other old world Cypripedia and have their counterpart in the 
Selenipedia of South America. : 
From Reichenbach’s description of the plant we take the following. He regards C, Sanderianum as a near ally 
of C. philippinense and the recently introduced Roebelenii, but having more affinity with the latter on account of the 
narrower sepals, which, in C. philippinense are broadly deltoid. The leaves are long, broad, and of a bright green colour, 
and shine as if varnished. The flower stems have a deep reddish-purple velvety covering, and bear from three to five 
flowers. The green bracts have a purple hue outside, are ciliate at the edges, and striped with darker purple. The sepals 
are very concave, triangular lanceolate, with dark purple veins, and beset with stiff hairs. The petals are linear and tail-like, 
and grow 18 inches in length; they are broader at the base, where they are of a rich reddish-purple mottled with a light 
hue; the tail-like portions of the petals are blackish purple, and their tips are quite blunt. The pouch is similar in shape 
to that of C. Stoneiand is of a dark brownish-red hue. As to the staminode it is distinct from that of any of the other 
species. : 
Plants which have flowered with us have borne as many as three flowers on a stem, hence it may be expected that 
when they become well established they will produce strong, many-flowered spikes. The plant from which our plate was 
prepared had an extremely fine appearance and remained in flower for a considerable time; the tails of the petals, the most 
remarkable part of the flowers, continued to increase in length for several days until they reached fully 18 inches. 
C. Sanderianum is a native of the Malayan Archipelago, therefore needs a warm house, like its near allies C. Stonei 
and others. So far as we have been able to judge it is of free growth, and from the fact that several plants flowered 
simultaneously in February, soon after we received it, we presume that it is more free in flowering than others of the 
group. It should be grown in pots in a mixture of fibrous peat and loam, with sufficient sand to keep the compost open. 
Like all Cypripediums, it requires plenty of water during growth, but the leaves must be kept dry during winter, as owing 
to their great substance, they are liable to rot spots. It should be well guarded against sun rays, and be grown shady all 
the year round. We regard C. Sanderianum as one of the most extraordinary, and, at the same time one of the most 
beautiful, of the genus. It is a discovery of our collector, J. Férstermann.
