disc rich deep brown, and the third is primrose-coloured, with a light maroon 
disc. The difference incolour is remarkable. A light rosy variety of D. x 
Ainsworthii is the result of crossing D. nobile virginale with D. aureum. 
Mr. Black asks where the rosy colour has come from as it does not appear 
in D. aureum. A correct answer would solve many difficulties, but we 
consider it to be another case of reversion, like that recorded at page 57, 
excepting that in this case the cross has been reversed. 
Four hybrid Paphiopedilums are sent from the collection of H. T. Pitt, 
Esq., Rosslyn, Stamford Hill, by Mr. Thurgood, three of which are forms 
of hybrids already known. P. X nitens giganteum x villosum aureum is 
a very handsome form of P. Colossus, and has regained much of the 
villosum character, from which it is three-fourths derived. The dorsal 
sepal, however, is broader, and green with a lighter margin and some large 
dark brown blotches. The broad petals, as well as the lip and staminode, 
strongly recall P. villosum. A second is from P. x MHarrisianum x 
villosum, and thus is a form of P. x conspicuum. This also is three- 
fourths derived from P. villosum, with which it most agrees in shape; the 
dorsal sepal, however, is much suffused with deep shining brown, in which 
the character of P. barbatum is seen. The third is said to have been 
derived from P. insigne Brownii X nitens var. Almos, which would make 
it a form of P. Romulus, but from the general shape of the flower and 
the colour of the dorsal sepal it might well be a form of the preceding. 
The fourth is said to be from P. exul x Calypso, and bears a general 
resemblance to the seed-parent in shape and colour, in fact the influence 
of P. Spicerianum and P Boxallii is scarcely apparent. The parentage of 
the two last seems to require confirmation. 
A flower of a brilliantly-coloured form of Odontioda Bradshawiz is 
sent from the collection of R. G. Thwaites, Esq., Streatham, having 
rather broader segments than the original form, and with distinct crimson 
markings on a yellow ground. Mr. Black remarks: ‘‘ The pollen parent 
was a full rosy Odontoglossum crispum, and it is curious to know where 
the marbling has come from, as it resembles in this respect the original 
Odontioda Vuylstekez. Had a blotched crispum been used the markings 
would have been readily explainable.” 
VANDA x MOOREI, - 
ANOTHER plant of this very interesting natural hybrid has appeared, a 
flower having been received for determination from Messrs. Sander & Sons, 
St. Albans, though without any note of its history. The hybrid originally 
appeared in the establishment of Messrs. J. W. Moore, of Bradford, nearly 
twelve years ago, in an importation of V. Kimballiana, and was described 
by the writer (O.R., v. p. 329). It received an Award of Merit from the
