O.' RUCKERIANUM, Bchh.f. — ^A rare and handsome Orchid, dedicated to the 

 late Sigismund Eucker, Esq., in whose collection it first flowered. It was one 

 of the first to appear of those mysterious plants which are now generally looked 

 upon as natural hybrids, and is quite a gem, probably having 0. crispum for 

 one of its parents. The habit and general character agrees with 0. crispum, 

 but the flowers difEer much in colour. The lanceolate cuspidate s,epals and 

 petals are creamy white with a border of deep violet, and a few oblong spots of 

 brown on the inner surface ; the oblong ligulate acuminate lip, which is angulate 

 on both sides at the base, is yellow in that part, and has two or three chestnut- 

 brown blotches in the centre. The petals havi3 the chestnut-brown basilar lines
