ORCHIDS AND HYBRIDIZING. 219 
scarlet, lip pale lilac bordered with amethyst and 
tipped with rosy purple. 
But one natural hybrid has been identified among 
Dendrobes—the progeny doubtless of D. crassz- 
node X D. Wardianum. Messrs. J. Laing have a 
fine specimen of this ; it shows the growth of the 
latter species with the bloom of the former, but 
enlarged and improved. Several other hybrid 
crosses are suspected. Of artificial we have not 
less than fifty. 
Phaius—it is often spelt Phajus—is so closely 
allied with Calanthe that for hybridizing pur- 
poses at least there is no distinction. Dominy 
raised Ph. irroratus from Ph. grandifolius x Cal. 
vestita ; Seden made the same cross, but, using the 
variety Cal. v. rubro-occulata, he obtained PA, pur- 
pureus. The success is more interesting because 
one parent is evergreen, the other, Calanthe, 
deciduous. On this account probably very few 
seedlings survive; they show the former habit. 
Mr. Cookson alone has yet raised a cross between 
two species of Phajus—Ph. Cooksont from Ph. 
Wallichit x Ph. tuberculosus. One may say that 
this is the best hybrid yet raised, saving Ca/anthe 
Veztchit, if all merits be considered—stateliness of 
aspect, freedom in flowering, striking colour, ease 
of cultivation. One bulb will throw up four spikes—
