CHLORANTHY IN ANEMONELLA THALICTROIDES. — From Miss Emily 
T. Fletcher I have recently received an interesting specimen of 
Anemonella thalictroides, Spach. It has eight flowers in the usual 
umbelliform inflorescence, the central one being much shorter-stalked 
and somewhat larger than the rest. In all the flowers the sepals 
are small (2 to 4 mm. long) and green, instead of white and petalloid 
as usual. The stamens are all converted into sessile elliptic-oblan- 
ceolate green and sepaloid structures. They are 1.7 to 2.4 mm. 
long and rounded at the apex. "The carpels are of the usual number 
and shape and are provided with stigmas of normal appearance. 
Miss Fletcher writes that the specimen was collected on the Bunce 
Farm at Westford, Massachusetts, where this peculiar form of the 
plant has been known to grow for six or seven years. 
In the Gray Herbarium I find a specimen from Waterbury, Con- 
necticut, collected and sent to Dr. Gray by Mr. W. H. Patton. In 
this plant the inflorescence seems originally to have been 6-flowered, 
although only three flowers have matured. Of these the central one, 
which is long-stalked and larger than usual (nearly 2 cm. in diameter) 
is completely transformed by chloranthy. The sepals are green 
although bordered with white. The stamens are represented by nar- 
row flat elliptic-oblong slender-stiped structures, very different in their 
attenuate stipitate bases from those in the Westford plant. The 
carpels are also modified to very short and sessile but somewhat leaf- 
like members, quite destitute of stigmas.
