altogether being fairly intermediate, as 15 : 15. The whole plant, in form 
and colour, favouring P. barbatum as 382 : 31, or 50°7 per cent. 
(2) (c) P. x Harrisianum III.—A third variety of the same parent- 
age. In form, P. barbatum is prepotent in the habit of growth, leaves, 
and staminode ; in all, favouring that parent as 19:16. Jn colour, P. 
barbatum predominates in the leaves, bract, upper sepal, and staminode; 
altogether favouring that parent as 17:12. The whole plant, in form 
and colour, favouring P. barbatum as 36 : 28, or 56:2 per cent. 
(3) (a) P. x Leeanuwm gigantewm.—A hybrid out of P. Spicerianum 
(Pfitz) by P. insigne (Pfitz), var. giganteum, raised by Messrs. Heath, of 
Cheltenham. In form, the parent P. Spicerianum is prepotent in the 
leaves and upper sepal, while P. insigne predominates in the petals ; in all, 
airly intermediate as 17:17. Jncolour, P. Spicerianum preponderates

in the upper sepal and petals, altogether favouring that parent as 18 : 15. 
The whole plant, in form and colour, favouring P. Spicerianum as 35 : 32, 
or 52°2 per cent. 
(3) (b) P. x Leeanum superbum.—A hybrid of the same specific parent- 
age, raised by Mr. Chas. Winn, of Birmingham ; but in this case P. insigne 
Chantinii was the parental variety. In form, P. Spicerianum is pre- 
potent in the upper sepal, lower sepal, and petals, while P. insigne pre- 
dominates in the habit of growth, leaves, lip, and staminode ; in all, 
favouring P. insigne as 22:17. In colour, P. Spicerianum preponde- 
rates in the upper sepal, while P. insigne prevails in the lower sepal and 
staminode ; altogether favouring P. Spicerianum as 17:16. The whole 
plant, in form and colour, favouring P. insigne as 38 : 34, or 52°7 per cent.
