These particular varieties were possibly 

 further crosses with the white parent, a known 

 example ol which wc ha\c in hcllciuensc 

 (ioocliristiense x crispuin). A noteworthy 

 occurrence is the manner in which the yellow 

 colour IS lessened by the influence of the white 

 parent ; one would expect it to gradually lose 

 its intensity, but this is not so, only the central 

 area of each sej^ment becomes whiter, while 

 the outer portion retains the yellow in a 

 marked degree. 



Not content with Nature's productions, the 

 hybridist set about making superior varieties 

 by crossing the best parents procurable. The 

 adjoining illustration shows a remarkal:)ly 

 fine variety of harvengtense (triumphans x 

 crispum) — the loochristiense of early days — 

 raised by Mr. de Barri Crawshay. The ground 

 colour is primrose-yellow, while the markings 

 are also characteristic of triumphans, especially 

 the large blotch on the labellum. 



Although the varietal name aureum has 

 been applied to varieties in which some of 

 the characteristic blotching is absent, thus 

 exposing a larger area of dull-yellow ground 

 colour, there is quite another meaning to this 

 descriptive term, and one which must always 

 be remembered. It is to be found in 

 triumphans aureum, a rare variety with the 

 ground colour of honey-yellow on which 

 deeper yellow blotches are superimposed. In 

 the one form of aureum the blotching, without 

 any change in itself, is merely reduced m 

 area ; in the other form the whole of the 

 blotching remains, but is changed from the 

 normal brown into a deep yellow tint, which 

 appears indistinctly on the honey-yellow 

 ground, and produces to all intents and 

 purposes an albino or xanthic variety of the 

 species. In 1914 Mr. F. Menteith Ogilvie 

 flowered a xanthic variety of O. Jorisianum 

 (triumphans x luteopurpureum), a most inter- 

 esting result obtained by him through the use 

 of yellow varieties of these two well-known 

 species, and fully described in the ORCHID 

 World, Vol. IV., p. 199. 



Of the garden raised hybrids of triumphans 

 probably Vuylstekei is the best known. The 

 result of crossing harvengtense (crispum x 

 triumphans) and Wilckeanum (crispum x 



Odonloglossum harvengtense Crawshayanum. 



luteopurpureum), it produces richly blotched 

 flowers, the large percentage of crispum 

 ensuring" fairly round shape. By adding 

 Harryanum to Vuylstekei we obtain Vuyl- 

 stekese, an improvement both in vigour and 

 coloration. In Vulturia (Vuylstekea; x 

 triumphans) we have a very handsome flower 

 of chestnut-red colour, with bright golden- 

 yellow tips to the segments, and of which an 

 excellent example received a First-class 

 Certificate, Manchester Orchid Society, 

 May 13th, 191 5, when exhibited by Mr. Philip 

 Smith, of Haddon House, Ashton-on-Mersey. 



Amongst the primary hybrids of triumphans 

 that have turned out successfully are Queen 

 iVlexandra (triumphans x Harryanum), the 

 outstanding feature of which is the immense 

 labellum with its bold blotching and rich 

 coloration, and Leao (triumphans x Hallii), in 

 which the two yellow grounds have made a 

 brightly coloured flower. Quite a large 

 number of hybrids have been recorded in 

 which triumphans, crispum, Pescatorei and 

 Harryanum are included m the parentage. Of 

 these mention may be made of Wiganianum 

 (Rolfeas x harvengtense), Tristan (triumphans 

 X crispo-Harryanum), Catherine (harveng- 

 tense X eximium), Telemachus (excellens x 

 harvengtense) and Queen of Gatton 

 (triumphans x percultum), of which an 

 illustration appears on page 158.
