' Phaius  Marthae. Hybridus inter P. Blumei et P. tuberculosum artificiosa fecundatione productus. 
Phaius X Marthae Horr., Fourn. of Hort., 1894, I, cum ic. 
yy, his beautiful hybrid first appeared in public at a meeting of the Royal 
ee) Horticultural Society, London, on March 13, 1894, when it attracted 
much attention and was unanimously awarded a First Class Certificate. 
The Society’s Yournal described it at that period as having the form of 
P. x Cooksoni (P. Wallichii x P. tuberculosus) but a different colour of a pale 
nankeen yellow, with the base of the lip striped with purple, the front lobe being 
washed with bright rose. In P. x Cooksoni the sepals and petals are clear rose 
longitudinally shaded with a brownish yellow median band; the basal portion of 
the lip is yellow, while the anterior portion is suffused with rose on each side and 
stained with carmine rose. 
The resemblance between P. x Cooksoni and P. x Marthae is readily explained 
by the close relationship which marks their origin. In fact the two hybrids have 
one parent common to both, namely P. tuberculosus, and the two other species 
which have assisted in their production are very near to each other. REICHENBACH 
expressed the opinion that P. Blumei and P. Wallichii, as well as P. grandifolius, 
might well be regarded as forms or sub-species belonging to the same type. 
The editor of the Botanical Magazine when describing P. Wallichii expressed a 
similar opinion. The following differences may be noted: P. Blumei has wider 
segments than P. Wallichii, and of a deeper shade and somewhat marbled. These 
differences, however, are not absolutely fixed as the three forms just mentioned 
are very variable. As to the other parent, P. tuberculosus, it is perhaps the most 
highly valued and the finest of the genus, and is already known to the subscribers 
of the Lindenia, having been figured in the seventh volume. 
In a word, it may be seen from our plate that the hybrid now pour- 
trayed is quite intermediate between the parents, and favours more particularly 
P. tuberculosus in form, and P. Blumei in colour. The plant from which our artist 
prepared the painting was exhibited by Mr. A. Van Imscuoor at a meeting of the 
ORCHIDEENNE on Jan. Io last, when it achieved a great success, the Judges 
unanimously awarding it a First Class Certificate of Merit. 
By comparing it with the descriptions cited above, it will be seen that 
it comes somewhat nearer P. X Cooksoni, but this is not astonishing, considering 
O32.
