Aucust, 1908.] THE ORCHID REVIEW. 
living plants and flowers, and was arranged to show the geographical distri- 
bution of O. crispum, its range of variation, the species with which it grows 
intermixed, and the natural hybrids which have been found in importations 
of it. Numerous examples were shown in illustration of the fact that in 
what may be called the Pacho and Velez districts O. crispum was remark- 
ably variable, and included a large and varied series of blotched varieties, 
while in the Popayan district, where the variety Lehmanni grows, very little 
variation occurred, and there was an absence of the blotched varieties found 
in the other districts. The latter was illustrated by two sheets of specimens 
selected by the late Consul Lehmann, and the two former by a series of 
dried specimens and numerous coloured plates from M. Goossen’s Diction- 
naire des Orchidées. Next came the five species which are known to grow in 
company with O. crispum, namely, O. gloriosum, O. Lindleyanum, O. 
luteopurpureum, O. Hunnewellianum, and O. triumphans, the two latter in 
the Velez district only, all of which were known to hybridise with O. 
crispum, followed by the respective natural hybrids (in the same order), O. 
x Andersonianum, *O. X Coradinei, *O. X Wilckeanum, *O. X Adriane, 
and *O. xX _ harvengtense (loochristiense). Then came the four known 
combinations between these other species, namely, O. X mulus (gloriosum 
Xx luteopurpureum), O. X acuminatissimum (Lindleyanum  X_ luteopur- 
pureum), O. X previsum (gloriosum X Lindleyanum), and O. X Hudsoni 
(gloriosum X Hunnewellianum). Lastly came five artificial hybrids of O. 
crispum, namely, O. X armainvillierense (with O. nobile), O. X crispo- 
Harryanum (with O. Harryanum), O. X Lambeauianum (with O. X 
Rolfe), O. x Thompsonianum (with O. Edwardii), and Odontioda Brad- 
shawiana (with Cochlioda Neetzliana), to show the intermediate nature of 
the hybrids, and the way the characters of the parent species were com- 
bined. The living plants exhibited were O. crispum, O. Lindleyanum, O. 
luteopurpureum, O. Hunnewellianum, O. triumphans, O. nobile, and O. xX 
harvengtense, and there were cut flowers of O. X Wilckeanum, O. xX 
Adriane, and O. X armainvillierense. 
In a short paper accompanying the exhibit attention was called to the 
fact that O. crispum has been artificially crossed with three of its hybrids, 
yielding the secondary hybrids O. X Fascinator (with O. x Adrianz), O. 
X crispodinei (with O. x Coradinei), and O. X Stewartianum (with O. x 
Andersonianum), some, at least, of which can be fairly matched among wild 
plants that were formerly considered as blotched forms of O. crispum. The 
remarkable variability of O. X Fascinator was also pointed out, and this 
was held to confirm an opinion long ago expressed that many of the 
so-called “ blotched crispums ” were not simple varieties of that species, but 
hybrids of secondary or of more complex parentage, due to the fact that 
*An asterisk indicates wild hybrids that have also been raised in gardens.
