THE ORCHID REVIEW. 



•95 



Mr. Potter seems to hesitate in using the new compost for Odonto- 

 glossums, and he gives reasons for the same, though he intends to make 

 fresh trials, and remarks " It is quite possible I may yet have all my estab- 

 lished crispums in the new material."' I have no doubt that the result o" 

 Mr. Cookson's experiments will receive careful consideration, and perhaps 

 lead to further developments. 



I am more than ever convinced that an admixture of oak and beech 

 leaves to the compost used in potting epiphytal Orchids is beneficial, 

 because by their gradual decay they supply the necessary plant food, and 

 the experiments now in progress are likely to show us the best way of using 

 them. Argus. 



ODONTOGLOSSUMS FROM STAMFORD HILL. 



Several beautiful Odontoglossums are sent from the collection of H. T. 

 Pitt, Esq., Rosslvn, Stamford Hill, N., by Mr. Thurgood. O. crispum 

 Pittise is a fine form, slightly tinged with pink on the sepal-, which organs 

 bear a number of bright red-brown spots, arranged in two more or less 

 transverse groups, while the spots on the sepals are mostly confluent into 

 one very irregular central group. The lip is rather small and narrow, and 

 bears many red-brown blotches on the disc. O. c. Princess Victoria has 

 broad, beautifully undulate segments, with the red-brown blotches on the 

 petals very regularly distributed, but those on the sepals and lip rather 

 larger and somewhat irregularly and partially confluent. The lip is fairly 

 broad and of good shape. Another form has the markings reddish purple, 

 these consisting of a single blotch just below the middle and several 

 small splashes round it, while the lip is prettily spotted. This, we 

 think, is not yet fully developed. A fourth is a very fine flower, 

 slightly tinged with blush, with a very few small red-brown spots on 

 the segments, chiefly on the lip. O. triumphans, Rosslyn variety, is a very 

 fine form, and remarkable for the very heavy rich brown blotches, the 

 remaining ground colour being bright yellow. O. X loochristiense, Rosslyn 

 variety, has the petals nearly white, with a single large dark brown blotch 

 near the apex, and only a few small ones below, while the sepals are very 

 heavily blotched with dark brown on a light yellow ground. O. X 

 Wilckeanum The Alake is a very large form, with white ground, and the 

 segments long, the sepals being very heavily blotched with deep red-brown, 

 and the much toothed petals and lip bearing smaller blotches. Lastly 

 may be mentioned two pretty forms of O. X Adrian*, having a white 

 ground colour, but one much more heavily blotched than the other. They 

 form a very beautiful series.
