their deciduous allies, but require warm treatment throughout the year. 
The evergreen species should not be so severely dried off, but should receive 
sufficient moisture to prevent the foliage from suffering. The whole of the 
New Guinea species require pretty similar treatment. 
D. LINGUIFORME (fig. 13) represents a plant of such a totally different 
character that the uninitiated would not recognise it as a Dendrobium at 
all. And its peculiar leaves might very well be taken for pseudobulbs. It 
belongs to the small section Rhizobium, and is a native of Queensland and 
New South Wales. It was originally described over a century ago by 
Swartz, and was introduced to cultivation about the year 1860, by Mr. Hill, 
of the Brisbane Botanic Garden, who sent living plants to Kew, where they 
soon flowered, and the species was figured in the Botanical Magazine 
Mig. 13: DENDROBIUM LINGUIFORME. 
(t. 5249). The present figure is from a plant which flowered in the collection 
some time ago. It succeeds well in a small basket suspended from the 
roof, and flowers annually. The creeping rhizomes are woody, and on 
them are produced alternately the elliptical-oblong, very fleshy leaves, 
in reference to which the name was given. The flowers are borne fn slender 
axillary racemes, and have very narrow pure white segments, with a few 
pink spots on the lip, and a little yellow on the disc. D. cucumerinum, 
Lindl., is a closely allied species, which took its name from the resemblance 
its leaves bear to little cucumbers. It is figured at t. 4619 of the Botanical 
Magazine. D. teretifolium, R. Br., is another nearly allied plant, though
