broad margin of light yellow-green ; lip white, blotched and spotted with

rolled over the column, the anterior lobes spreading, with crisped and 
undulate margin.

ODONTOGLOSSUM LAUDATUM.—Many of the blotched crispums of years 
ago were natural hybrids between that species and O. luteopurpureum, and 
to-day recognised as varieties of Wilckeanum. The blotching derived from 
luteopurpureum was the principal feature of attraction, although along with 
it also came much of the yellow ground colour, frequently giving a cloudy 
appearance to the flower. One or two rare instances were seen in which 
the blotching occurred ona white ground, and the effect was then much 
more pleasing. In the early days of artificially produced Odontoglossum 
hybrids, a fine result was produced in O. laudatum (Wilckeanum x arden- 
tissimum), first raised by Mons. Vuylsteke in 1907. During the last few 
weeks an excellent variety has been in flower in the collection of Geo. A. 
Wood, Esq., of Harrogate. The large flower has all the segments hand- 
somely blotched with brownish-red on a white ground, the spiny crest on 
the base of the labellum strongly indicating the luteopurpureum influence.
