52 THE ORCHID REVIEW. (Marcu, 1917 
unmanageable.” Inhabit the plant recalls a dwarfed state of E. Peetersiana, — 
the scape being about three feet high, and bearing sixteen flowers and buds. 
The flowers are over 2} inches across; the sepals and petals bright rose- — 
purple, and the three-lobéd lip white inside, tipped with purple, and having © 
seven rows of crested yellow keels on the disc. It is said that the time from — 
the fertilisation of the flower to the development of the ripe capsule and 
the germination of the seeds was three months, and we do not recall any ; 
other epiphytic Orchid which develops so quickly.

T the meeting of the Linnean Society held on February 15th, Sir © 
David Prain, K.C.M.G., F.R.S., in the Chair, a series of Orchids, — 
flowers, and paintings was exhibited by Mr. R. A. Rolfe, A.L.S., to show 
variation and segregation of hybrid character. There were three series of 3 
Odontioda, all seedlings from O. Charlesworthii (Cochlioda Neetzliana X 
Odontoglossum Harryanum), the pollen parents being Odontoglossum 
crispum, O. Phoebe (cirrhosum X crispum), and O. Harryanum, giving 
respectively Odontioda Madeline, O. Patricia, and O. Brewii. Of the first 
there were living flowers of thirteen seedlings out of the same capsule, 
showing various shades of crimson and red, these having been sent by 
Messrs. Armstrong & Brown, Tunbridge Wells. The other two series 
were paintings from Messrs. Charlesworth & Co., Haywards Heath, also 
varying greatly. Of five forms of Odontioda Patricia from the same 
capsule one showed a considerable amount of reversion towards the Odonto- 
glossum parent, both in shape and colour, while of seven forms of Oda- 
Brewii one closely resembled Odm. Harryanum in colour, though not in 
other details. Paintings of all the parents and grandparents were included. 
Lycaste Janetz (Rossiana X Skinneri) was represented by paintings, by 
Mrs. Janet Ross, of four out of a batch of twelve seedlings from the same 
capsule, raised in the collection of the late Mr. H. J. Ross, Poggio Gherardo, 
Florence, these showing various shades of cream and pale yellow in the 
ground colour, with or without rose spotting on the sepals, and with or 
without a maroon blotch at the base of the lip, thus showing segregation 
(due to incompatability) in what is presumably a primary hybrid. 
The next case was that of a hybrid sporting, also from the collection of 
Mr. H. J. Ross. Cypripedium Dauthieri (barbatum x villosum) is 4 
hybrid fairly intermediate between the parents (which were also shown)- 
This sported successively to an irregularly striped form (var. Rossianum), 4 
much paler form (var. Vanninii), a harlequin-coloured form, green 0? 
one side and purple brown on the other (var. Janet Ross), and to a form
