all characters except color of the blossoms winch were 
bright, not pale yellow. These plants were growing in 
very rich soil in low shady woods. A portion of the plant 
was pressed and three flowers from it are now in my her- 
barium. Mr. Billings transplanted part of the cluster into 
his garden, putting them into less rich soil and masun- 
nier spot than where they naturally grew. In 1905the 
characters of these plants were so far changed that they 
would pass very well for the small-flowered plant, Cyprt - 
pedium parviflorum. The whole plant had become shorter 
and slenderer with narrower foliage, the lips of the flow¬ 
ers less than an inch in length (some were two inches at 
the time when transplanted), lips not appreciably flat¬ 
tened laterally and in fact not any longer possessing the 
characters of the large-flowered plant.” 
Knight continued by saying that for some few years 
he had annually transplanted into his garden clumps ol 
plants which agreed in all essential characters with t. 
parviflorum , although some superficial differences were 
noted, such as various shades of color in the lip. A er 
five years he found that the plants, with regard to foliage 
and flowers, had increased in size to the extent that they 
resembled C.pubescens. The plants, which were originally 
found in moss in a cold bog and had flowered later than 
the middle of June, after being transplanted into very 
rich soil in a sunny exposure were seen to flower as ear y 
as the third week in May. Nearly all the stalks bore wo 
flowers, whereas they had originally borne rarely more 
than one flower. He also made the interesting observa¬ 
tion: “One season two stalks from the same plant ore 
flowers whose lip on one stalk was laterally compresse 
while on the other it was strongly compressed from a- 
bove, there being one flower on each of these sta * , 
(Professor Ames tells me that he has observed both ° 
the above-mentioned types of flowers growing on
