tent, stigma bilamellate broad, capsule elliptic 

 2valve unilocular, polysperme, seeds scrobicu- 

 late inserted on 4 large placentas. Perennial^ 

 ramose, flowers axil, pedunculate — I now add 

 another beautiful N, (t. to the Gentianides: it 

 is next to Swertia and Narketis, but with the 

 calix and corolla of Sabatin Slc. My JSarke- 

 tis fl. tel. 477 based on various sp. of pentan- 

 drous Stcertias included even several G. this, 

 another my Synallodia japonica, with 2 sta- 

 mens united, formed by Swertia rolata of Thun- 

 berg ; and Gentiana pratensis with very une- 

 qual calix and no appendages ? perhaps another 

 Leimanisa 11. ihe name of this applies to the 

 large bilamellate stigma, it shows beautifully 

 the opposition of stamens essential to the Gen- 

 tianides.
