164 THE ORCHID REVIEW [Juty, 1916 
ans] 
MONG tthe seedling Odontoglossums which have become so numerous 
during recent years is a type of albino of the O. crispum xanthotes., 
set, of which examples have frequently appeared in the choice groups 
staged by Messrs. Charlesworth & Co. at our horticultural meetings, and 
we recently had the pleasure of seeing a charming little group of them in 
their fine establishment at Haywards Heath. They are among the most 
beautiful of recent acquisitions, the purity of the white ground colour and 
the clear yellow blotches giving a very charming effect. They represent 
a quite distinct type of albinism, for while both the rosy tinge of the sepals 
and the brown markings of the column and lip are suppressed, the blotches 
are almost invariably present in the sepals and lip, affording a pleasant 
contrast to the numerous blotched forms. From a decorative standpoint 
they are comparable to some extent with the beautiful Phalaenopsis 
amabilis, with the advantage, as Mr. Charlesworth well pointed out, that 
they can be grown in a greenhouse temperature, a quality that ensures for 
them an increased popularity in the future. 
The original O. crispum xanthotes appeared many years ago. as an 
imported plant, the colour being white with an occasional clear yellow spot 
on the sepals and lip. Subsequently others appeared, of better shape and 
with more numerous yellow spots. It was one of these, united with an albino 
of O. Pescatorei that gave the charming O. armainvillierense xanthotes, and 
this, crossed with O. crispum xanthotes Charlesworthii, gave the equally 
beautiful O. .eximium xanthotes.. Messrs. Charlesworth also raised a 
number of seedlings from O. crispum xanthotes Cooksonii crossed with 
O. c. x. Charlesworthii, and we saw examples of all of them in bloom. 
Some of the two latter batches are very difficult to distinguish. The 
albinism proves constant, for Mr. Charlesworth remarked that in no case 
was there any reversion to purple. It is a triumph of hybridisation, 
representing years of perseverance, and it says much for the improved 
methods of culture now in vogue. 
We also saw a beautiful series of the blotched hybrids in the the raising 
of which the firm has been so successful, and a brilliant lot of Odontiodas, 
some of which appeared at Chelsea a few days later. One particularly 
interesting batch of seedlings was Odontioda Charlesworthii recrossed with 
Odontoglossum Harryanum, showing a remarkable range of variation, the 
most extreme of which closely resembled O. Harryanum in the pattern and 
colour of the markings, while the shape was that of ordinary Odontioda 
Brewii. Almost at the other extreme may be mentioned the brilliant 
es ORCHIDS AT HAYWARDS HEATH.
