collected it there. It has since been imported in quantity from some 
neighbouring locality, and is now one of our most popular garden Orchids. 
D. FirzGEraLp! is a very curious plant. It was described by F. Mueller 
in 1884 (Melbourne Leader), Feb. 1884), being based on a plant figured by 
Fitzgerald as D. superbiens (Austral. Orch. ii. pt. 1, t. 5), but which is not 
Reichenbach’s plant of that name. It is said to have been obtained from 
Northern Queensland, and flowered in the Greenhouse of the late Sir W. 
MacArthur. It has almost exactly the habit, drooping inflorescence, and 
undulate flowers of D. undulatum, but the petals are rather broader, and 
the colour is rose-purple. The plant appears to be a hybrid between D. 
undulatum and D. superbiens, and Fitzgerald himself remarks that its 
characters would almost lead to the supposition that it had arisen from 
hybridisation between D. undulatum and D. bigibbum, or some other of the 
lilac-flowered species found in Australia. It is still only known from the 
original unique specimen. 
D. X LEEANUM was described in 1891 (O’Brien in Gard. Chron., 189gI, 
li. pp. 640, 641, fig. 88), as a handsome new species imported with D. 
Phalznopsis var. Schroederianum by Messrs. Sander. It was described as 
having pseudobulbs about three feet high, and sprays of flowers arranged 
after the manner of D. superbiens, but different in all points, more especially 
in the open form of the lip. It received an Award of Merit from the R.H.S. 
on November roth, 1891. On seeing it I immediately suggested that it 
might be a natural hybrid between D. Phalznopsis and D. superbiens, as it 
was fairly intermediate in character. Soon afterwards two other plants 
appeared, in the collection of Sir Frederick Wigan, at East Sheen; and with 
Mr. H. V. W. Wade, of Singapore, the first of them, called var. 
atropurpureum, being darker in colour than the original. I then pointed 
out the unmistakable resemblance to both parents, and the intermediate 
character of the crest (O.R., iii. p. 334). It remains excessively rare. 
D. x STATTERIANUM.—In 1889 a plant was described and figured under 
the name of D. Phalznopsis var. Statterianum (Retchenbachia, ser. 2, i. p. 
15, t. 7). It had appeared in the establishment of Messrs. Sander at St. 
Albans, in an importation of the typical form. The flowers were rather 
smaller and darker than in the type, and the lip was obtuse. Other plants 
subsequently appeared showing similar characters, and in 1893, noticing a 
distinct resemblance to D. bigibbum, I suggested that this form was a 
natural hybrid between D. bigibbum and D. Phalznopsis (O.R., xi. p. 284). 
I have since discovered that D. bigibbum superbum represents a similar 
anomalous form, characterised by its rich purple colour, generally similar 
floral structure, and the absence of the characteristic white crest on the lip. 
It is said to have been introduced by John Gould Veitch, and received a
