scent in some tropical Orchids—indeed, it is an interest- 
ing subject to consider how plants resemble each other in 
this particular. Then there are large numbers of Orchids 
with such delicate odours that some are unable to appre- 
ciate them, but they are specially grateful to those who 
detect them. Again, some Orchids have different odours 
at different times in the day. It is not safe, therefore, to 
declare a plant scentless unless it has been tested repeatedly 
at different times. 
Variation in odour has been noticed. We remember 
flowering the first Odontoglossum hebraicum, and on. test- 
ing it its odour was of cinnamon. It passed to Sir Trevor 
Lawrence’s collection, and we asked the late Mr. Spyers to 
test the odour, and he replied that it was of Hawthorn, like 
others of its class. He tested it several times with the same 
result, but for some time before it passed off he reported 
to us that it smelt exactly like cinnamon. Then there are 
odours in Orchids about which opinions are divided as 
to whether they are pleasant or not. Oncidium ornitho- 
rhynchum is an example ; some like the odour of it very 
much, while it is disagreeable to others. The same applies 
to Anguloas, some Lycastes and Stanhopeas with strongly 
aromatic scent, which are pleasant at a distance, but not 
so when too closely approached. But the majority are 
distinctly pleasant, Cattleya Dowiana and its hybrids, C. 
Eldorado and others, being delicately fragrant. 
A very few are malodorous, Bulbophyllum Beccari not 
being tolerable under any circumstances, the flowers smell- 
ing like some of the Stapelias,
