36 THE ORCHID REVIEW. [ FEBRUARY, 1907. 
Dendrobium X Ainsworthii, Cattleya x Iris, &c., to which varietal names 
can be added without complication whenever necessary, is what the Vienna 
Congress recommends, and these rules should be as binding on horticul- 
turists as on botanists. If they are loyally adopted we shall soon be able to: 
answer a question which the Gardeners’ Chronicle once asked—‘ Shall we: 
ever have a universal language ?’—in the affirmative. 
I am very glad to see that the Vienna Congress adopts some of the 
very points which I long ago urged—or, to put it in another way, we have 
both urged the necessity of adopting a system of nomenclature for which we 
have to thank a long line of patient and clever men, and which can be 
understood throughout the civilised globe, which no mere vernacular system 
could accomplish. Let us not forget a very pertinent remark that the 
Gardeners’ Monthly once made.—*‘‘ VERNACULAR NAMES.—We have a 
suspicion that common names made all that trouble at the Tower of Babel.” 
I will conclude by remarking that if raisers and others will ascertain what 
the Vienna Rules do require, and proceed to adopt them, it will be better 
for all concerned.

HABITAT OF ODONTOGLOSSUM CRISPUM. 
By Fiorent Crags. 
THE habitat of Odontoglossum crispum extends over a considerable 
expanse of mountains, which can be divided into four regions, as. 
follows :— 
I. Fusagasuga. 3. Chiquinquira. 
2. Pacho. 4. Velez, 
I. FUSAGASUGA REGION.—This is already too well known for the 
very poor quality of the species found in it, the flowers being starry and 
without substance. The plants from this region are easily recognisable by 
their long pseudobulbs, generally bright green in colour, and very succulent ; 
they become dull and wrinkled some days after collecting. O. crispum 
grows here in company with O. luteopurpureum, O. gloriosum, and 
O. Lindleyanum. Here one finds also O. Lindeni growing generally on the 
ground, on the mountain sides, among the grasses and small shrubs, but 
at a higher altitude than O. crispum. 
2. PacHo REGION.—This is the grand region, producing the plants 
known in commerce under the name “ Pacho type.” Owing to its extended 
area, I have subdivided it into two divisions. The first is composed of the 
district properly calied Pacho, and is isolated by the high plains of 
Facatativa and Lubachaqué. It comprises the group of mountains which 
stretch from Agua-Larga in the direction of La Vega, and from that last
