42 THE ORCHID REVIEW. 
expanded the accuracy of M. Warpur’s observations was fully realized, 
so difficult was it to distinguish them from those of the epiphytal species 
represented in the Botanical Magazine, and this led to an examination of 
all the available materials, including an authentic flower from M. Thouars 
himself, preserved at the British Museum. This investigation resulted 
in the surprising discovery that the plant introduced by M. Warpur 
was none other than the original P. tuberculosus, and the one which 
has been known in gardens under this name for the last twenty years 
is something different. 
Phaius tuberculosus was originally figured by Thouars in 1822, under 
the name of Limodorum tuberculosum (Thouars, Orch. Iles Afr., t. 31), 
the figure being prepared, as the author informs us in the preface, from 
nature, though it. represents only the inflorescence, with analytical 
details of the flowers; and the details of the stem and leaves are: not 
added in the brief synopsis of species. Fortunately, however, information 
which. is sufficient for our present purpose is supplied in the synopsis of 
genera. Here the author established a new genus for the plants 
represented in his plates 31 and 32 (the latter called Limodorum 
villosum, a native of Bourbon), under the name Gastorchis, which he 
placed in the division Terrestres, as opposed to the other division which 
he termed Parasites. Any doubt that might have arisen about the _ 
correctness of Thouars’ observations under this head are removed by an 
examination of his original figure and an authentic flower, for the details 
of the crest are markedly different in the two species. Gastorchis, it may be 
added, was afterwards reduced to Phaius by Blume, and the present speci2s 
became Phaius tuberculosus (Mus. Bot. Lugd. Batav., ii, p. 181). It is 
therefore clear that the name has been transferred from the terrestrial to 
the epiphytal species. : 
The confusion began with Reichenbach, as may be seen from the 
following note which appeared in the Gardeners’ Chronicle, in 1881 
(xv., p. 428) :— , 
“This is a very novel beauty. I have at hand a newly developed 
peduncle with only six fine flowers, in a few years no doubt there will be 
seen under Box Hill racemes with twenty flowers. They have rather 
stellate sepals and petals of. fine white, and an exceedingly fine lip with 
wide yellowish lateral lobes, covered over and over .with brown blotches 
on an anterior, obcordate, wavy middle lacinia, white, with mauve marginal 
spots. Three callous orange plates with numerous 
centre, directed towards a tuft of light sulphur- 
suffice to embarrass many small inserts. They are perhaps attracted by 
similar small hairs which stand scattered on the side lacinie. The column 
is white, with some light purple tint in front. 
impressions stand in the 
coloured hairs which must
