286 THE ORCHID REVIEW. [SEPTEMBER, IQII- 
the name of G. Tracyana, Rolfe, has been given. It was unanimously 
resolved to recommend the award of a Botanical Certificate, on the ground 
of novelty. 
‘MALFORMED ODONTOGLOssSUM.—A spike of a form of Odontoglossum 
crispum from Sir Julius Wernher, of Luton Hoo, bearing several malformed 
flowers, as well as others of a normal character, was referred to Mr. 
Worsdell, who reports as follows: ‘‘ The balance of the spike is quite upset. 
Most of the flowers are normal, however. The peculiar structure present 
is due to a compromise between two tendencies, (1) that making for 
reduction or fission, and (2) that making for multiplication of parts. 
There is no evidence at all for actual synanthy or for the ‘ passing of one 
part of a flower into the next,’ as the spatial distribution of the flowers on 
the spike appears to be normal. On the other hand there is an equal 
absence of evidence that an increase in the number of flowers on the spike 
is occurring. In one flower there is a remarkable case of ‘ positive dedouble- 
ment’; four sepals, uppermost (posterior) forked; four ordinary petals 
(which might have resulted from forking of the lateral ones); one of these 
four lies exactly in the median plane (anterior); two labella forming with 
the column a whorl of three within the four ordinary petals; the column is 
double below, but triple above (there being three anthers). One anther is 
becoming petaloid. Owing to the causes above mentioned the flower 
comes to havea larger number of members than usual, and the composition 
of the. whorls is altered, owing to the fact that, under the circumstances, 
the members must be more or less re-arranged, so as to obey the law of 
alternations. In the second flower there are three normal sepals, but the 
anterior one is, in structure and appearance, intermediate between a sepal 
and a petal, as it has the brown blotches of the former; but it is lighter in 
colour than the sepals, and has a slight tendency to be fringed at the 
margin like a petal; there is no present evidence as to its origin, but it 
perhaps arose by division of the normal sepals, two labella forming with 
the double column or whorl of three. In the third flower the reductive or 
fusion tendency has overpowered the other (or multiplicative). The two 
lateral sepals have fused into a single one in the anterior median plane, but 
this sepal is triple, and the middle lobe may represent the third sepal-like 
petal of the second flower referred to, and this is very likely, in which 
«ase it would not be accurate to speak of fusion of two sepals. Two 
labella, one of which is much smaller than the other and has its stalk 
completely fused with the column. The column is double, but the anthers 
are much more closely approximated than in the last two flowers (an 
interesting fact as showing the fusing process). The sepals are more petal- 
like and larger than usual, as is natural. In the fourth flower the reduction 
and fusion tendency is all-potent; the flower is 2-merous. It has two
