diameter when fully expanded. The colour of the sepals and 
petals is light rosy lilac, the apex of the lips richly mottled with 
crimson-purple, and the column is smaller -than in Mossice, and 
has a two-lobed crest, which I have not observed in any other 
of the species. Should this character with the habit of the plant 
prove to be constant, I should think it will be a good specific 
distinction. 
“ The plant was introduced to the Tooting Nursery about 
eight years ago from La Guayra. It is a plant of easy culture, 
requiring to be potted in very fibrous peat, and to be elevated a

as to prevent the lodgement of any superfluous moisture about 
the base of the stems, and should be freely watered while in a 
growing state, but with a considerable reduction through the 
resting season. If it should happen to commence growing in 
the winter months, which some of these plants are apt to do, 
it is better to err in giving too little than too much water, it 
being far preferable to have a small winter shoot than to lose 
its growth in the summer, which is sure to be more vigorous 
and flower finer than any of those made in winter.

ON THE NATURAL ORDER LYCOPODIACEtE, 
By Mr. T. Moore. 
The natural order Lycopodiaceas contains, besides Lycopodium , 
the genera Psilotum and Tmesipteris, to which, by DeCandolle 
and others, is added Isoetes. Their general habit is that of moss¬ 
like plants, with imbricated leaves and creeping stems. In some 
instances they assume the character of stemless plants, having 
erect subulate leaves, and a solid cormus; among those of the
