292 THE ORCHID REVIEW [OcTOBER, 1915- 
The fact is the Law of Priority is only one of several rules that have 
been imposed for the purpose of securing an orderly nomenclature, which 
must be applied together in order to be effective, and it is the adoption of 
one rule while ignoring the others that makes all the mischief. Clearness 
and brevity are the first objects of a rational nomenclature, and ever since 
the time of Linnzus the rule has been that specific names should consist 
of a single word. Of course it did not prevent synonymy arising, and 
with this came the practice of selecting what was considered the best name, 
and sometimes of substituting a new one that was thought to be more suit- 
able. This led to protests, and in course of time the Rule of Priority was 
added. It has always been a vexed point as to how far the rule should be 
applied, and the climax came when it was extended to names that are not 
in accordance with other rules. The difficulty arises from the fact that 
some people apply the rule to everything, not even excluding specific names 
consisting of as many as six words, or of an unspecified number of 
syllables, while others refuse to apply it at all. At all events they say it 
should never be used to preserve ugly names, or to displace those that are 
suitable, and this is the view taken by our correspondent. 
But this is treading on dangerous ground, for when once the principle 
is admitted one never knows where to stop. The name Leliocattleya 
luminosa is so admirably descriptive that one cannot help wishing the 
plant had never been called L.-c. Truffautiana. As to which was the 
earlier name, see page 252 of our tenth volume. 
ANGULOA BREVILABRIS, Rolfe.—At the last Holland House Show an 
Anguloa that had been imported with A. Cliftonii was exhibited by Messrs. 
Sander & Sons, St. Albans, under the name of A. Ruckeri, together with a 
natural hybrid that appeared in the same importation (see p. 243). A plant 
from this importation has flowered in the collection of Walter Cobb, Esq., 
Normanhurst, Rusper, which proves to be very different from A. Ruckeri in 
the shape of the lip, and Messrs. Sander believe that the one they exhibited 
isidentical. The same thing, labelled A. Ruckeri, also occurs in the collec- 
tion of Consul Lehmann, and is localised as collected in September, 1891, 
between Cativo and Buritica, Western Andes of Antioquia, at 1,400 to 1,600 
metres altitude (n. 7235). On soaking out a flower the lip is seen to be 
identical in structure. The flower bears such a resemblance to A. Ruckeri 
that the difference was not noticed until looking inside and seeing the very 
different lip, this being about half as long as in A. Ruckeri, and having 
very broad truncate side lobes, and a small oblong fleshy front lobe. :., The 
parentage of the natural hybrid, Anguloa Rolfei, Sander (p. 255), now 
requires to be amended to A. Cliftonii x brevilabris.—R.A.R.
