86 THE ORCHID REVIEW. 
There is one other variety which deserves to be distinguished, namely 
that with the shape of C. x s. flavescens, but the colour ivory-white, which 
appeared with Messrs. B. S. Williams and Son. It almost combines the 
Shape of C. macrocarpum with the colour of C. Bungerothii, and may be 
called C. x s. eburneum. 
Distinct as are some of the varieties named, it is probable that their 
limits will be somewhat obscured in future by the appearance of intermedi- 
ate forms, a few of which have already appeared. Several of them are very 
handsome, and it is to be hoped that they will help to popularise this very 
remarkable genus. All the flowers which have hitherto appeared have been 
males, but it is quite possible that females. may also turn up on a future 
occasion. It would be rather interesting if some one would make the 
experiment of hybridising the two species artificially.

PHAIUS x AMABILIS AND P. x MARTHA. 
Flowers of these two beautiful hybrids, both of which have received First- 
class Certificates from the Royal Horticultural Society, have been sent by 
Messrs. F. Sander and Co., St. Albans, and afford evidence of the value of 
Phaius tuberculosus to the hybridist. PB. x amabilis is a seedling from P. 
grandifolius, and was raised both by Messrs, Veitch and Messrs. Sander, 
the former flowering it first. The’ sepals and petals are blush-pink in front 
and white behind, while the lip, which most resembles P. tuberculosus in 
shape, is rich reddish purple, with a yellow line down the centre and a pale 
throat. P. x Marthe was derived from the allied P. Blumei, and _ has 
lighter yellowish pink sepals and petals, a similar front lobe to the lip, but 
the side lobes and the throat broadly striped with reddish purple. The 
allied P. x Cooksoni, the first of the group, is an equally brilliant form, and 
has received a similar award—in fact, the three form a very charming trio. 
It was raised in the collection of Norman C. Cookson, Esq., from P. 
Wallichii, the pollen parent being P. tuberculosus, as in the two preceding 
cases. The miffy habit of this species is eliminated in the hybrid offspring, 
while the size and vigour of the other parents are brought down within 
reasonable limits, and the colour greatly enhanced. This is a particularly 
promising field for the hybridist, and we anticipate the advent of many.other 
beautiful forms. Already we have P. x maculato-grandifolius, with its 
unique colour, and the brilliant P. x Owenianus, derived from P. bicolor 
and P, Humblotii, and when these are further intercrossed, and the blood of 
some of the brilliant Calanthes introduced into the group, some striking 
results may have to be recorded.’ And as-they are so easily raised and 
cultivated; and. so quickly reach the flowering stage, there is all the more 
inducement to take them in hand. Oe 3 ret ng ail
