The various secondary crosses of the 

 Harryanum hybrids when coupled have an 

 extraordinary similarity, as naturally they 

 should have. I have just bloomed Rolossa, 

 and have open at the same time a plant of 

 Prince Edward (Rolfea; x crispo-Harry- 

 anum). Except for colour and size of spots 

 and markings on the lip, one description would 

 fit them both. They are not out of the same 

 pod, as I did not raise this particular Prince 

 Edward. 



As pedigree is interesting, and fast 

 becoming impossible to remember, I am 

 manufacturing names to indicate as much as 

 possible the parents which last were used to 

 produce crosses, but this will not be possible 

 for long. In a few generations more I expect 

 that we shall produce crosses that will appear 

 to have been the result of totally difterent 

 parents than those we have used, or, in other 

 words, many crosses will produce the same 

 permutations. The IMendelists will have a 

 very difficult skein to disentangle. 



Rolossa has a white ground on which are 

 clearly arranged the deep jjlum-purpie 

 blotches and spots. Those on the sepals are 

 in three whorls, the outermost one being 

 " islanded," as m Rolfea?, the ti|)s being 

 coloured at the back, showing through to the 

 front. The petals are similar, but " eye- 

 browed," and have a central Ijasilar 

 longitudinal blotch (akin to Smithii, but not 

 so solid) the length of the column. The 

 pandurate lip carries the basilar spotting of 

 nobile, and is also spotted round the edge. 

 \ he crest is orange, and the column white. 



Unfortunately, this, the first of the cross to 

 bloom, is of open form, but when the good 

 one comes it will be a fine thing. Harryanum 

 has gone down before the influence of nobile 

 on each side of the parentage, showing 



always how strong and pure a species it is 

 compared to crispum.

 Mr. Armstrong has commenced mtroducing 

 hybrid Odontoglossums of a very high 

 standard, these " half-brothers " being 

 exceedingly fine. When at Orchidhurst 

 recently I was delighted to see the early ones 

 of these two crosses opening in such fine 

 varieties. 



Of course, they vary from flowers of 

 absolutely solid crimson-brown and also of 

 bluish purple hue to complete absence of 

 colour. In form the best ones are perfect, 

 being almost as round as a pansy, and in 

 some cases are too round (to my mmd) to be 

 beautiful, as the hexagonal outline proper to 

 an Odontoglossum becomes a smooth 

 circular outline. 



The lip in most cases is white, carrying a 

 central blotch and some basilar spots. The 

 cohinms of the solid-coloured forms are deep 

 crimson-brown. 



Owing to the almost identical parentage, 

 the description of one applies to the other.
