* The discovery of a new species of Cypripedhim in the Malay PeninsiUa 

 deserves some mention here, as unquestionably the small group of Malay- 

 sian Cyprij)edia is the handsomest of the genus. The new species G. san- 

 derianum is probably the most wonderful-looking flower in an order where 

 wonderful structures are the rule. The leaves are long, broad, and of bright 

 green colour, shining as if varnished. The flower stems are deep reddish- 

 purple, with velvet covering, bearing from three to five flowers. The green 

 bracts are purplish outside, striped with darker purple within and ciliate at 

 the edges ; sepals very concave, triangularly lanceolate, covered with stiff 

 hairs and dark purple veins : petals linear like long dependent thongs some 

 18 inches in length, broader at the base, with transverse lines of rich red, 

 mottled with pale cream colour. The thong-like portions are blackish 

 purple with peculiar rounded, slightly swollen terminations. The long 

 dependent curled and almost snake-like petals, as they are seen emerging 

 from the half-open buds, are very singular and beautiful, and must be seen 

 to be appreciated. The group of Malaysian Cyprlpedia includes only about 

 nine species, namely — C. plutytcenium, glanduliferum, philippiriense (or 

 Icevigatum), haynaldianum, parishii, roebelenii, stonei and lowii. All differ 

 considerably from other Cypripedia, having their counterpart in the 

 Selenepedia of S. America. C. sanderianum is a near ally of C. roebelenii 

 and G. philippinense. (See " Reichenbachia," by F. Sander, Pt. I.May, 

 1886, p. 7).
