Ohs. This is the type of the species. The form from which the 

 character given in the Prodromns was taken--thp one flj^^ured in the 

 ninstrations No. 2. presents n form so distinct that it might t)e consi- 

 dered a difl'erent species did not intermediate forms prove them only 

 varieties.

 tapes fium its back, 



79. Hymenodictyon excelsum "^all Cinchona orcelsa Roxb. Cor. pi.

 ties analogous to those of Peruvian bark)--2. An exnandtMl flower-- 

 3. The corolla split open to show the position of the stamens--4- 

 Ovary and calyx— 5. The capsule burst, dehiscence loculicidal — 6. 

 The same cut transversely, showing the form of the placenta. 



Ohs. The febrifuire properties of the bark of th's plant having re- 

 cently **rigaged the attention of the Drug Committee, I have rerjub- 

 lisheS this fitrure from that now very scarce work, Roxburgh's Coro- 

 mandel plants, in the hope that, malting it generally known to the 

 present medical service may be productive of advantage, hy enabling 

 those favourably situated forgetting it to institute experinit^ints un 

 the bark. 



80. Hymenodictyon obovatum Wall, natural *?>p— TThe figure dif- 

 fers somewhat from the description but not apparently enough, 

 to constitute it a distinct species)— 2. A dissected flower, the corolla 

 separated from the ovary and split open, the calyx superior— 3. Ovary 

 cut transversely— 4. The same cut vertically-l5. A young capsule, 

 natural *?^^--6. The same cut transversely—7. The same cut verti- 

 cally--^. The mass of imbricated seed removed from one cell— 9. 

 A single seed detached, all with the exception mentioned more or less 

 magnified. 



Ohs, This figure is here introduced with the same object in view, 

 as the last, ancf both with the h^ipe that beneficial consequences 

 may result.
