NOTES: 
DENDROBIUM CRUMENATUM.—In the Philippine Islands the yellow 
stems of this plant are used for purposes of ornamental weaving. In the 
economic plant collection of the Bussey Institution of Harvard University 
there is a riding whip, the handle of which is covered with interwoven 
strands taken from the stems of Dendrobium crumenatum and from a 
Species of fern, probably from Lygodium circinnatum.—OakeEs AMES, -in 
Orchidacea, 1922, 96. 
LYCASTE FULVESCENS.—The peculiar drooping habit and the uncommon 
colouration of the flowers of this species are among the prominent 
distinguishing features. It was discovered by Linden in 1842 on the 
eastern Cordillera of Colombia, at 6,000 feet elevation, near Ocana, and 
afterwards collected by Schlim and Wagener. It was first cultivated in this 
country by the Rey. John Clowes, of Manchester, in whose collection it 
flowered in 1845. 
SOUTH AUSTRALIAN OrcuHIvs.—At the meeting of the Linnean Society, 
held at Burlington House on May 4th, Mr. Edwin Ashby exhibited pressed 
Specimens of Orchids from South Australia, including a number of the 
spider-like members of the genus Caladenia, and the green-hooded forms of 
the genus Pterostylis: ° many of these have a sensitive labellum, which, on 
the entrance of an insect, closes up the entrances for a short period; Mr. 
Ashby suggested that this was for the purpose of fertilisation. A species of 
Thelymitra, which only opens its bright-coloured petals during hot sunshiny 
days, and two species of Caleana were exhibited, both provided with a 
sensitive labellum, which, on being touched, folds up in two separate 
movements. A species of Diuris intermediate between D. maculata and D. 
longifolia, although now a fixed form, seems certainly to have been derived 
by hybridisation. For many years before it was described by Dr. Rogers as 
Diuris palachila, Mr. Ashby had known it under his own name of D. 
hybrida, thinking it could hardly deserve specific rank. A very beautiful 
form known us Caladenia tutulata, intermediate between the genera 
Glossodia and Caladenia, was also shown and its characters explained.
