EXPERIMENTS IN HYBRIDISATION, &c. 101 
(6) P. x Ashburtome Laforcadei, a hybrid raised by M. Bauer, of 
Paris, out of P. barbatum by P. insigne Chantini. Jn form, the parent 
P. barbatum is prepotent in habit of growth, leaves, lip, and staminode ; 
while P. insigne preponderates in the lower sepal and petals; in all, 
favouring P. barbatum as 20:18. Jn colowr, P. insigne predominates in 
the lower sepal. Altogether the hybrid is fairly intermediate, as 15:15. 
The whole plant, in form and colour, favouring P. barbatum as 35 : 38 
or 51:4 per cent. (Fig. 20.) 
(7) PB. x apiculatum, a hybrid raised by Mr. D. V. Drewett, of Riding- 
Mill-on-Tyne, out of P. barbatum (Pfitz) by P. Boxalli (Pfitz). In form, 
the parent P. barbatum is prepotent in habit of growth, leaves, and 
staminode, while P. Boxalli predominates in the petals; in all, favouring

P. barbatum as 26:21. In colowr, P. Boxalli preponderates in the bract, 
petals, and lip, while P. barbatum prevails in the staminode; altogether 
favouring P. Boxallias 19:15. The whole plant, in form and colour, 
favouring P. barbatum as 41: 40, or 50°6 per cent. (Fig. 18.) 
(8) P. x selugerwm, a hybrid out of P. barbatum (Pfitz) by P. philip- 
pinense (Pfitz), raised by Messrs. Veitch. Jn form, the parent P. barbatum 
is prepotent in the leaves, while P. philippinense predominates in habit 
of flowering, ovary, and lower sepal; in all, favouring P. philippinense as 
20:19. In colowr, P. barbatum preponderates in the lip, while P. philip- 
pinense prevails in the leaves and lower sepal; altogether fairly inter- 
mediate, as 16:16. The whole plant, in form and colour, favouring 
P. philippinense as 36:35, or 50°8 per cent. (Fig. 15).
