4 THE ORCHID REVIEW. [JANUARY, 1922. 
epiphytic Orchids, when these have an upright infloresence, but if the 
latter is pendent; as in Stanhopea Devoniensis, no twisting takes place, as 
the lip is already pointing downwards. IE, however, a young spike of 
Stanhopea be fixed in. an erect position, the ovaries will twist in 24 hours 
(Kerner, Pflanzenleben, ii. 224). It would be an interesting experiment to 
‘See whether terrestrial Orchids, if placed with the spike in a reversed 
position, would refrain from twisting their ovaries. 
The twisting of the ovary is not a genuine morphological character, but 
a biological function securing the correct position of the flower in respect 
to visiting insects. It appears to be of little, if any, value from a systematic 
oint of view. 
ORCHID COLLECTING IN THE EAST. 
By T. SoMa, ToKyoru, JAPAN. 
EAVING my home about the middle of February, 1921, I travelled 
{ through Shanghai, Hongkong, Canton, the Philippine Islands, 
British North Borneo, Singapore, Burma, India and Java, the journey 
occupying over six months. While in the Philippines I went to Tayabas 
Province, a famous locality for Phalenopsis Schilleriana. Here there is 
thick virgin forest, and many savage people, called Ayetas, live in the 
jungle. The Ayetas are one of the lowest classes among over sixty tribes 
in the Philippines. They are a small black people, always naked, and they 
live in houses made of palm leaves and constructed on the branches of high 
trees. By means of the primitive wooden bow they shoot animals with 
hhateful poison. A few years ago, an American dealer of Philippine Orchids 
‘was killed in the jungle by their fearful shooting when collecting Phalz- 
nopsis Schilleriana and P. leucorrhoda. | went into the virgin forest with 
my attendant, two guides and several Ayetas, and also collected these 
Phalznopsis, as well as P. amabilis, P. Lueddemanniana, and others. 
The Ayetas climb up any high tree, just like monkeys, so long as there 
are strong vines hanging from it. They do not require money in return for 
their work, but want tice, tobacco, spirits, matches and red cloth. And 
this because they do not know how to use money or even to count any 
numbers. My guide told me that if a man could calculate the numbers 
from one to ten he is considered a great and wise person among them. 
I found that Phalzenopsis Schilleriana is now very scarce in this locality, 
and.will probably become more so in the near future. . When climbing up 
the mountain, about 8,000 feet high, I saw Cypripedium Argus, Dendro- 
bium Victoria Reginz, many kinds of Ccelogynes, Dendrochilums, Aérides, 
and others. On the lower part of this mountain there are many Dendro- 
biums, such as D. superbum, D. aureum philippinense, and Cypripedium
