May-JUNE, 1920.] THE ORCHID REVIEW. 7¥ 
called O. crispum nigrescens, of the Black Prince type, several of them in 
bud being easily picked out by their dark colour. Unfortunately the origin 
is uncertain, as the seed parent was purchased as a plant of unknown 
parentage, but in two that were expanded the influence of O. Hunne- 
wellianum could be traced, probably through some form of O. Adriane. 
O. Rolfeze xX Hunnewellianum was also pointed out, being a spike of light 
yellow flowers blotched with brown. The seedlings were an interesting lot,. 
and persevering efforts have been made for a long time to get over the 
difficulty of raising them with certainty, though with the common experience 
of only partial success. Some were germinating on the compost of the 
parent plants, and there were tiny globules in various stages, though others. 
had made no progress. We were also shown a number of glass tubes which 
had been prepared and sterilised after the approved methods, but the seeds. 
did not germinate after sowing, so that the old method was the most 
‘successful. Other seedlings had been pricked off and were in various stages 
up to flowering size. The Disas were an interesting lot, and we saw an 
example of D. Italia with four flowers, anda good batch of seedlings 
obtained from this Disa recrossed with D. grandiflora, the attempt to obtain 
a plant with the vigour of D. Luna and the colour of D. grandiflora having 
been carried forward another stage. Disas were thriving well at one end of 
~ the Odontoglossum house, and D. Luna was in bud. D. sagittalis grows 
very freely here, and there were over a dozen spikes of its pretty white 
flowers. An interesting little Japanese Orchid was pointed out which we 
have not previously seen alive, namely Gymnadenia rupestris, of which there 
were several spikes, and the Orchis-like, lilac flowers just beginning to open. 
The remaining houses were filled with growing stock, largely hybrids of 
the Cattleya group, in the most robust health, and a good number were 
showing for flower, with a few already expanded. Among the latter were 
examples of the richly-coloured Lzliocattleya Dominiana, Lc. H..T.. Pitt 
(Le. bella x C. Enid), a very showy hybrid, Lc. Aphrodite, C. Suzanne 
Hye, examples of Maxillaria Sanderiana, Pleurothallis Birchenallii, near 
P. scapha: but darker in colour, Masdevallia calura and O’Brieniana, and 
other interesting things. 
The plants are grown on open stages, with leaf mould and other 
moisture-retaining materials on a solid stage beneath, and the whole stock 
is clean and in excellent condition. It is interesting-to record that there is 
no scale in the nursery, and this is necessarily accompanied by the 
condition that any new plants have to undergo a period of quarantine to 
prevent the re-introduction of the pest. Messrs. Flory & Black must be 
congratulated on the excellent condition of the plants generally, and on the 
efforts they are making to maintain the reputation of this pioneer establish- 
ment. The work is being continued on progressive lines, and the constant
