or the adjacent islands. ‘Then we have D. bigibbum, D. superbiens, and 
D. Goldei, all having very attractive purple flowers... D. speciosum is a well- 
known white flowered species which makes an imposing display when well 
grown, and between this and the pretty little rose-coloured D. Kingianum 
there seems to be a curious set of natural hybrids whose history has already 
been given (O.R., xvi. p. 88). D.undulatum is a very robust species bearing 
long pendulous racemes of bronzy flowers, while in D. Johannis the spikes 
are erect, and the flowers of a dusky blackish brown. Somewhat 
approaching the latter in habit but differing in colour, we have D. 
canaliculatum, which is sometimes met with, also the dwarfer D. 
gracilicaule. D. emulum has short racemes of white flowers. D. 
tetragonum is a remarkable species, and rather rare in gardens, while

D. Smilliz is the single representative of the Pedilonum section, and has 
dense spikes of white flowers, tinged with rose, and the lip green. D- 
teretifolium is a very graceful plant, bearing long whip-like leaves and 
pendulous spikes of white flowers with very narrow segments, and when 
well grown is very effective. Lastly we may mention the remarkable little 
D. linguiforme (fig. 30), and D. cucumerinum (Bot. Mag., t. 4019), i0 
which the leaves have been well compared to little gherkins. Plants of 
this remarkable species are in the collection of Sir Jeremiah Colman, Bart., 
at Gatton Park. 
Sarcochilus Fitzgeraldii and S. Hartmannii are both pretty little 
representatives of a rather large genus, whose members are not often met 
with in cultivation. Phaius grandifolius and Calanthe veratrifolia are tw0
