Not to be confounded with O. x spectabile, L. Lind. (Liiid. xi. t. 523), 

 which is beheved to be a form of O. x excellens.

1903, 183; 1904, 54.— Vuylsteke, 1902. 



First recorded as a doubtful hybrid between O. triumphans and O. tripudians, 

 but afterwards O. x Denisonar was suggested as the second parent, though the 

 matter requires confirmation.

21. 0. X Wattianum (Harryanum x Lindleyanum), O.R. 1900, 299, 314, 

 323; 1904,235; G.C. 1900, ii. 214, 286, f. 83 (v. Crawshayanum).-Crawshay, 

 1900. 



Originally described in 1890 as possibly a natural hybrid between 

 O. Lindleyanum and O. luteo-purpureum (Rolfc in G.C. 1890, i. 354), and after- 

 wards, in deference to the opinion of the collector, as possibly a distinct species 

 (Reichenb. ser. 2, i. 19, t. 9), though intermediate in habit between O. Lindley- 

 anum and Harryanum. Its real origin, then suspected, has since been proved 

 by iMr. Crawshay.
