first introduced hybrid, others from a different parentage in which 

 P. 8 chiller iana may have participated. There is thence in cultivation 

 a group of supposed natural hybrids, which have originated from 

 P. Aphrodite, P. Schilleriana, and P. rosea. 



Among the experiments undertaken by Seden in hybridising 

 species of Phalgenopsis one has proved to be of exceptional interest 

 from a scientific point of view. He fertilised Phalcenojjsis rosea with 

 the pollen of P. Aphrodite, and the resulting progeny was the 

 P. intermedia, of Lindley. This was the second instance in which 

 the existence of natural hybrids among orchids has been proved by 

 direct experiment.* Subsequent crosses between other species have 

 resulted in adding several beautiful and distinct forms to the list of 

 cultivated Phalaenopses. 



Hybrid Phalaenopses thence fall under two headings, the first 

 comprising those introduced from the habitats of the species from 

 which they have been derived ; the second, those raised artificially 

 in the glass houses of Europe. In accordance with the course 

 adopted in this work, the hybrids derived from the same pair of 

 species are brought under the same name, and deviations from the 

 first described form are described as varieties of that form. 



NATURAL HYBRIDS. 

 Phalsenopsis intermedia. 



Leaves as in PhaUhnopsis Aphrodite, but rarely attaining the dimensions 

 of the larger ones under cultivation. Peduncles usually paniculate, but 

 sometimes simple and racemose. Flowers about 2 inches in diameter ; 

 sepals elliptic-oblong, white ; petals also white, sub-rhomboidal, much 

 broader than the sepals ; lip with an incurved white claw spotted with 

 red, three-lobed ; the side lobes erect, orbicular-spathulate, light amethyst- 

 purple, the front lobe broadly cordate, -with two reflexed cirri at the 

 apex, reddish purple ; crest two-lobed, yellow spotted with red. Column 

 terete, amethyst-purple.
