Jury, 1913.] THE ORCHID REVIEW. 209 
is a very charming form, and we suggest for it the name of O. crispum var. 
Fletcheri. Figure 37 shows a seedling raised from O. crispum Jeanette 
crossed with the pollen of O. armainvillierense (ardentissimum).. This also

has an excellent shape, and broad segments, with a white ground colour, 
slightly tinged with rose, and numerous’ large claret-coloured blotches on 
each, while the lip has one large blotch in front of the crest, and a few 
smaller spots at the base. This we propose to call O. eximium var. Clarki. 
Both are charming acquisitions.

CONTINUOUS ORIGIN OF UNIT-CHARACTERS.—The brilliant progress in 
heredity of the last nine years, beginning in 1903 with the rediscovery of 
Mendel’s law, should not blind us to the four.broad inductions from 
paleontology, that transformation is a matter of thousands or hundreds of 
thousands of years, that to the living observer all living things may be 
delusively stationary, that invisible tides of genetic change may be setting 
in one direction or another observable only over very long periods of time, 
that discontinuous mutations or saltations may be mere ripples on the 
surface of these tides.—Dr. H. F. OSBORN
