To the Museum of Economic Botany : — From Mrs. Miller, Edin- 
burgh Castle; William Ivory, Esq., St. Roque; W. H. Macfarlane, 
Esq. ; Thomas Hay, Esq., Prospect Bank, Leith; Miss Yule, Inver- 
leith Row; Dr. Balfour; Professor Treviranus, Bonn; the Oregon 
Association; Rev. Mr. Waddell; Dr. Greville ; Mr. David Kerr. 
Professor Balfour announced the presentation to the Herbarium at 
the Botanic Garden, of aset of the specimens recently received by 
the Oregon Association, from their collector Mr, Jeffray. 
Exhibitions. 
Professor Balfour exhibited the male cone of a Cycadaceous plant, 
sent by Dr. Stanger from Natal, and named conditionally by Mr. 
Smith, of Kew, Stangeria paradoxa. The cone had been sent under 
the name of Lomaria eriopus, picked by Gueinzius at Port Natal, and 
details in regard to it and the plant have been recently given by Mr. 
Smith in Hooker’s ‘ Kew Miscellany.’ The leaves have a fern-like 
appearance, and are very like those of a Lomaria or Danza. The 
vernation is inflexed and involute, and the forked veins come from a 
true mid-rib. Mr. Smith remarks that the latter circumstance shows 
the untenable nature of the characters distinguishing fossil Ferns and 
Cycads. 
Professor Fleming noticed the occurrence of a remarkable white 
fungoid production on the roof of a dark cavern excavated for 
fire-clay in the sandstone quarry at Joppa, near Edinburgh. It 
seemed to be the mycelium of a fungus originating in the wood which 
propped up the roof of the mine. The white mass was seven feet in 
diameter. Some of the threads were pendant from the roof, and 
others had dropped on the floor of the mine. Dr. Macbean had 
examined the substance with a microscope, and found it to be com- 
posed of numerous cells arranged in a bead-like manner, but he was 
not able to detect fructification or spores. 
Mr. M‘Nab exhibited specimens of Lathrza squamaria collected by 
Mr. Peter Paisley, in a wood about a mile from Galashiels. 
Professor Balfour exhibited, from Messrs. P. Lawson & Son, speci- 
mens of glass labels for plants. 
Mr. G. Lawson exhibited, under the microscope, preparations of the 
colouring matters of the flower of Strelitzia Regine, and drawings of 
the same. This plant is interesting as presenting examples of both 
the xanthic and cyanic series in the same flower, but still more 
remarkable in the microscopical peculiarities of its colouring matters, 
which are referred to by Mohl in the ‘ Vegetable Cell,’ (p. 44). Mr.
