the disease. In the case of slugs or snails, these 

 oftentimes get brought in with the Sphagnum Moss. 

 This is frequently the case with the little Onion- 

 snail {Zonites allairia). These must he watched for 

 at night after dark, traps of Lettuce-leaves, sUced 

 Turnips, Potatoes, and such-like things being also 

 laid about for them. The cock-roach {£latta orien- 

 talis) is the great destroyer of the roots of Orchids. 

 There is, however, 

 no reason why this 

 beetle should be 

 more plentiful 

 amongst these 

 plants than any 

 others, and if 

 almost any of the 

 numerous pastes, 

 which are offered 

 for sale to destroy 

 them, be used per- 

 sistently, the house 

 can easily and 

 speedily be cleared. 



AcanthepUp- 



pium. — The name 



signifies " Spiuy- 



hoise," but how it 



bears upon the 



plants comprising 



this genus we £ire 



unable to say. 



They are terrestrial 



in habit and love 



the shade, and 



although not ap- 

 preciated by Or- 



chidologists of the 



first water, they 



are sufBciently ia- 

 teresting to deserve 

 a place in the most 

 recherche collection. 



As a genus, Acanthephippium is neaily allied to 

 Bletia, and is characterised by its short stout pseudo- 

 bulbs, and large broad-plaited leaves. The flower- 

 spikes seldom exceed the pseudo-bulbs in height, 

 but are very numerous. These bear from three to 

 seven or eight large, fleshy, ventricose flowers, 

 which are more or less bluntly spurred at the 

 base. They thrive best when planted in a some- 

 what closer soU than is usually considered suitable 

 for members of this order. Pot in rough peat, 

 leaf - mould, and loam. During the period of 

 growth water abundantly, but afterwards a good 

 season of rest will tend to the production of an
