January, 1922.] THE ORCHID REVIEW. 5 
Haynaldianum. In another place I collected Vandas, Aérides and Dendro- 
biums. In Mindanao and British North Borneo I could not go to the deep 
jungle, but I obtained Vanda Sanderiana, Phalenopsis Sanderiana and 
Aérides Savageanum in the former place. When in Burma I collected 
many kinds of the Orchids seen growing on high trees, including Vandas: 
and Aérides, while on the ground I found Cypripediums. 
At the time of my visit, Dendrobium chrysotoxum, D. formosum,, 
D. Pierardii and D. Devonianum were flowering profusely in the jungle. 
Others also in bloom and equally effective were Aérides affine, Saccolabium 
curvifolium, Vanda Bensonii and V. Parishii, as well as many species of 
botanical interest. The sight of these Orchids flowering naturally was to 
me an indescribable picture of elegance and beauty. And especially so was- 
Phalenopsis Schilleriana in the thick jungle. 
In northern India, at an elevation of 3-4,000 feet, many botanical 
species were flowering in the forest. A beautiful Coelogyne had flowers as 
white as the Himalayan snow. I visited Darjeeling (6,800 feet), but time 
did not permit me to go as far as Sikkim. When visiting Java I collected 
many flowering plants of Vanda tricolor, also Phalznopsis grandiflora, as 
well as Bulbophyllums. Unfortunately, a telegram calling me home 
prevented my intended visit to the Sarawak side of Dutch Borneo and to 
New Guinea. 
The plants collected by me were despatched to the Japanese Imperial 
Garden and my own home. On my return I at once went to my green- 
house in the garden and inspected the Orchids that had arrived from: 
England during my absence. I cannot express my pleasure in finding how 
healthy they all were, continually making new growths. Not a single one 
was lost.

MOVEMENTS OF THE POLLINIA.—The pollinia of many Orchids undergo: 
a movement of depression, after they have been removed from their places: 
of attachment and have been exposed for a few seconds to the air. This is 
due to the contraction of a portion, sometimes to an exceedingly minute’ 
portion, of the exterior surface of the rostellum, which retains a membranous 
condition. This membrane is likewise sensitive to a touch, so as to rupture’ 
in certain definite lines. In a Maxillaria the middle part of the pedicel, and 
in Habenaria the whole drum-like pedicel, contracts. The point of contrac- 
tion in all the other cases seen by me, is either close to the surface of 
attachment of the caudicle to the disc, or at the point where the pedicel is: 
united to the disc; but both the disc and pedicel are parts of the exterior 
surface of the rostellum. In these remarks I donot refer to the movements. 
which are simply due to the elasticity of the pedicel, as in the Vandex.—
