Queensland. The tree is a member of the Lauracez, and the timber is 
used locally for building purposes. In all fifty plants were found growing 
on this single tree, including seven species of Orchids, nine ferns, the 
semiparasitic Loranthus celastroides in full flower, and upon the latter the 
hyper-parasitic Notothixos cornifolius var. subaureus, or Golden Mistletoe. 
The Orchids were the so-called Rock Lily, Dendrobium speciosum, D. 
tetragonum, D. gracilicaule, D. teretifolium, Sarcochilus teretifolius, 
Sofalcatus, and Cleisostoma tridentatum. The latter grew on slender 
branchlets of the tree, but the others were attached to the trunk or main 
branches. There were several other flowering plants, but the majority of 
the species were made up of ferns, mosses and lichens, and these would 
provide suitable quarters for the other epiphytes. The assemblage of 
Orchids is interesting, and there is the possibility that under such condi- 
tions natural hybrids might occasionally be found, though we do not 
remember records of any that might be found in the above station.—R.A.R. 
T is with much pleasure that we are able to record the flowering of both 
sexes of another species of Cycnoches “on the same inflorescence,” in 
the collection of Mr. C. W. Powell, Balboa, Canal Zone, Panama. 
The females were three in number and the males five, and all are sent 
by Mr. Powell, but detached from the rachis. We believe they belong to 
C. Diane, Rchb. f., a species originally collected by Warscewicz on the 
Chiriqui Volcano, at 3000-4000 feet elevation, and described in 1852 (Bot. 
Zeit. x. p. 636), for the males agree well with two rather imperfect flowers 
of the type which were sent by Reichenbach to Lindley, and are preserved 
in the Herbarium of the latter. Nothing further, so far as we are aware, 1S 
known of the species, and the females have been hitherto unknown, so that 
Mr. Powell’s materials are of more than ordinary interest. This plant was 
received from Mr. C. H. Lankester, Costa Rica, and it is believed to be the 
first time that it has flowered. Reichenbach described the flowers as 
blotched with brown, in which and various other details it agrees with the 
present one. : i 
It will be interesting to give a summary of Mr. Powell’s description, 
which was taken from the living plant. Pseudobulbs about seven inches 
long by one broad. Raceme from the upper leaf axil, arched and pendulous, 
about a foot long, bearing five male and three female flowers. Male flowers 
green, heavily blotched with rosy brown; lip green, with thirteen finger- 
like processes, the basal pair twice as broad as the others, and #8 apex of 
the lip an obtuse triangle with a rosy brown dot at its point; column
