Trian drous Flowers. — Magnus * 

 describes a triandrous flower in 

 C^pripedium harbatum ; and I have 

 seen a flower of the same species 

 shown me by Mr. Lowne also with 

 three stamens, viz, Ai, ai, a2. In 

 two flowers of (7. Lawrenceanum 

 (fig. 5), received from Mr. Stevens, 

 the perianth was tetramerous and 

 dicyclic, while the androecium was 

 trimerous, the outer median stamen, 

 Ai, beins; fertile, and the two lateral ^ . -. _ . 



' i. 1 - • Cypripedium superhiens, 



stamens of the inner series, ai, as, plan of flower (fig. 3).— S, 



sepals; P, petals; COL, column 

 ., ,, . ,. or sfcarainode; at, ^2, inner ier- 



nodes, thus exactly reversing the tile stamens.
