44 THE ORCHID REVIEW. [FEBRUARY, 1922, 
ODONTOGLOSSUM CRISPO-SOLON VAR. CARMINETTA. 
HE name O. crispo-Solon indicates that this plant is the result of crossing 
‘ti O. crispum with O. Solon, the latter an artificially raised hybrid 
between Adrian (crispum x Hunnewellianum) and ardentissimum (crispum 
X Pescatorei). A first glance at this parentage does not indicate that 
more than the three species, crispum, Pescatorei, and Hunnewellianum 
are involved. But to these must be added the species luteopurpureum, 
for to it the blotching of the early-day “crispums” is due, and in the 
making of the above-mentioned ardentissimum a heavily blotched variety of 
“‘crispum ” was surely used. These so-called crispums are really forms of 
0. Wilckeanum, or, in other words, natural hybrids between crispum and 
luteopurpureum, inheriting the white ground of the former parent and the ~ 
spotting of the latter. 
About the year 1898 imported plants of O. crispum from a new locality 
began to flower. Spotted varieties again made their appearance, and were 
at first also described as crispums, but it was not long before the spotting 
was found to be due to the effect of a second species, in this instance O. 
Hunnewellianum. All these natural hybrids between crispum and Hunne- 
But with the raising artificially of blotched Odontoglossums greater oppor- 
tunities than in former times presented themselves. It is a remarkable fact 
that O. crispo-Solon is actually a combination of the two methods that 
Nature herself adopts in the production of blotched “crispums,” namely, 
surrounding area. The portion of the flower in t
