THE ORCHID REVIEW. 139 
intermedia, the first recognised hybrid among tropical Orchids, afterwards 
artificially raised in this country by Messrs. J. Veitch and Sons. 
Vandas, Aérides, and Saccolabiums are equally difficult to obtain from 
seed, though the reward of raising a startling novelty should be tempting. 
Numerous crosses have been effected with Vanda ccerulea, V. Sanderiana, 
V. teres, V. Amesiana, V. suavis, and V. tricolor, and the seed sown in all 
manner of ways, without any success. Wanda X Miss Joachim was raised 
in Singapore from V. teres and V. Hookeriana, and Mr. H. T. Clinkaberry, 
who has charge of the rich collection of the Hon. C. G. Roebling, Trenton, 
New Jersey, has been successful in raising seedlings between V. tricolor and 
Vanda Sanderiana, a most interesting cross. 
Lycastes are good seed-bearers, but seedlings are not so easily obtained 
as one would think when opening the large pod full of seed. When sown 
on a mixture of sandy loam and good fibrous peat they appear to germinate 
freely, but constant attention is required to rear them, and no time should 
be lost by pricking off the young plants if the seed-beds should show any 
signs of turning sour. Lycaste costata, with the beautiful fringed lip, is a 
desideratum for the hybridist, and Maxillaria Sanderiana crosses readily 
with Lycaste. Singularly enough this genus does not seem to have 
attracted much attention from the hybridist, though two seedlings have been 
recorded of Continental origin, namely, L. X schcenbrunnensis, raised at 
the Imperial Gardens, Schonbrunn, Vienna, between Lycaste Skinneri and 
L. Schilleriana, and L. xX Imshootiana, raised between L. Skinneri and L. 
cruenta. 
Zygopetalums are easily obtainable from seed, and have been used by 
various growers, more for experimental purposes than anything else, though 
several desirable hybrids have been obtained. It appears an inexplicable 
fact that seedlings raised from Zygopetalum Mackayi crossed with Odonto- 
glossum have flowered as Z. Mackayi pure and simple, and I can further 
place on record a similar instance which occurred with the Rev. © 
F. D. Horner, who had three seedlings of Zygopetalum Mackayi X 
Oncidium unguiculatum, which to all purposes are nothing else than 
Zygopetalum Mackayi. Z. X Sedeni (Z. Mackayi X Z. maxillare) is the 
first hybrid recorded, and is followed by several others, while the pretty 
Zygocolax X Veitchii (Z. crinitum X Colax jugosus) is of recent date. 
A large number of abortive and hazardous crosses have been made, and 
some quite unlooked-for results may yet be obtained. I may mention 
here a grower who boasted and showed seedlings of Lelia cinnabarina X 
Cypripedium caudatum Wallisii. Numerous experiments have been made 
to cross Cypripediums on Lzlias and Cattleyas, and vice versa, and in some 
instances the results have been astounding. A flower of Lelia cinnabarina 
crossed with the pollen of Cypripedium x Sedeni candidulum, and another
