"I don't know for certain, but I don't _think_ there are any orchids I
know that have aërial rootlets quite like that. It may be my fancy, of
course. You see they are a little flattened at the ends."

"I don't like 'em," said his housekeeper, suddenly shivering and
turning away. "I know it's very silly of me--and I'm very sorry,
particularly as you like the thing so much. But I can't help thinking
of that corpse."

"But it may not be that particular plant. That was merely a guess of
mine."

His housekeeper shrugged her shoulders. "Anyhow I don't like it," she
said.

Wedderburn felt a little hurt at her dislike to the plant. But that
did not prevent his talking to her about orchids generally, and this
orchid in particular, whenever he felt inclined.

"There are such queer things about orchids," he said one day;
"such possibilities of surprises. You know, Darwin studied their
fertilisation, and showed that the whole structure of an ordinary
orchid-flower was contrived in order that moths might carry the pollen
from plant to plant. Well, it seems that there are lots of orchids
known the flower of which cannot possibly be used for fertilisation in
that way. Some of the Cypripediums, for instance; there are no insects
known that can possibly fertilise them, and some of them have never be
found with seed."

"But how do they form new plants?"
